  • +Enhancement: #1530 polygon from 2 size tuple points
    +The effect of this feature is pretty basic: tuples or lists are used as constructor +arguments for implicitly creating an object in place of them. Hence, "(x,y)" can be +used instead of a vector or a point. In some cases, this leads to ambiguities and +the implicit resolution will fail however. +Specifically a list of size-2 tuples can be passed to the "points" arguments of +Polygon and Path. +

  • +Bugfix: #778 Use system font instead of hard coded "Monospace" +
    • +
  • +Bugfix: DRC "flatten" did not always flatten, but kept layers hierarchically +
    • +
  • +Enhancement: DRC: a couple of new filters on edge pair layers: +
      +
    • with_angle/without_angle: filter by angle of the edges (one or both)
      • +
    • with_length/without_length: filter by length of the edges (one or both)
      • +
    • with_distance/without_distance: filter by distance of the edges
      • +
    +
    • +
  • +Enhancement: Added Edge#cut_point method +
    • +
  • +Enhancement: LEF macro layouts now can be specified in UI +
    • +
  • +Bugfix: full_edge, negative output for fragmented polygon vs. small ones (space, enclosure, overlap).
    +In some cases, only parts of the edges were reported and negative output was +incorrect. In addition, negative output for two-layer checks - such as "l1.drc(sep(l2) > 0.2)" - now +only is produced for the primary layer. With both outputs it was difficult to separate the +components. +

    • +
  • +Enhancements: LEF/DEF reader.
    +Some highlights: +
      +
    • Support for layer map files
      • +
    • More complete spec support (e.g. FILL, MASK, FOREIGN, DO/BY/STEP ...)
      • +
    • Several bug fixes, e.g. routing layer switch for VIAs
      • +
    • Some functions also act on the transient selection (less mouse clicks)
      • +
    +
    • +
  • +Enhancements: Layout editing and rulers.
    +Some highlights: +
      +
    • Object properties now are changed without having to commit the dialogs
      • +
    • Dockable editor options windows
      • +
    • "Recently used" list
      • +
    • A "distribute objects" feature (Edit/Selection/Distribute)
      • +
    • Snap highlighting
      • +
    • Mouse tracking cursor indicates grid- and object-snapped location

      +
    • Bookmarks
      • +
    • Search in page (Ctrl+F)
      • +
    +
    • +
  • +Enhancement: Improved fill tool.
    +The fill tool now also supports skewed fill pattern repetitions +
    • +
  • +Enhancement: Ability to utilize a LayoutView as a Widget.
    +Standalone instantiation of a LayoutView object is +supported now. So it becomes possible to create +custom MainWindow UIs and embed a layout view there. +
    • +
  • +Enhancement: Improved layer and cell list filtering and searching +
    • +
  • +Enhancement: Experimental 3d (called 2.5d) view of layout.
    +For details search "2.5d View" in documentation. +
    • +
  • +Enhancement: Improved performance on sea of instances for OASIS files.
    +Iterated OASIS instances are stored and handled in a leaner way in viewer mode +
    • +
  • +Enhancement: Buddy scripts can concatenate files with "+" for input.
    +Concatenation happens by "blending files". Beware of the risk this implies. +A new option "--blend-mode" has been introduced for supporting overwrite, skip +and variant formation in case of cell name conflicts. See buddy script help. +
    • +
  • +Enhancement: Layer maps now support n:m layer mapping.
    +This allows mapping n input layers to one logical layer (merging) and also +one input layer to m logical ones (clone layer). This applies to the +buddy scripts and layer maps inside KLayout's reader. +
    • +
  • +Enhancement: include mechanism for easy include of files into DRC/LVS scripts.
    +This is a plain text substitution feature. Don't use it for Ruby or Python +scripts (the preferred way is still require/import). But it's a quick way +to include partial DRC and LVS scripts without having to worry about variable +scope. For details see "Including other files" in the documentation under: +KLayout User Manual/Design Rule Check (DRC)/DRC Runsets. +

    • +
  • +Enhancement: #521
    +Enhanced API for ObjectInstPath. +
    • +
  • +Enhancement: #487

    +LVS asserted on MacOS +
    • +
  • +Enhancement: #586
    +As a safety feature, the stream writers now refuse to write layouts +with cells carrying the same names. Writing such layers would result +in corrupted or invalid layout files. +
    • +
  • +Bugfix: #589 (tentative)
    +On Anaconda-based builds for MacOS 10.15 (Catalina) a loss of instances +was observed. This could be traced down to compiler/library incompatibilities +but not further. +
    • +

    +The "adjust origin" feature now allows specifying the target +coordinates for the adjustment. +
    • +
  • +Bugfix: #610
    +An internal error happened for certain hierarchical configurations on +netlist extraction. +
    • +
  • +Enhancement: LVS netlist compare
    +The algorithm was improved to provide better reproducibility. The +detection of matching paths in the presence of ambiguities was +improved. +In addition, the netlist compare now favours net names for resolving +ambiguities. So if nets are named the same in the layout and the +schematic, ambiguities are resolved based on these names. This is +usually more efficient. A new function is available to turn this +feature off: "consider_net_names(false)". +

    • +
  • +Enhancement: netlist object properties
    +User properties can be attached to the following netlist objects +now: Pin, Device, Circuit, Net and SubCircuit. Properties are +key/value pairs (keys and values can be strings can be strings +or numbers). +The property-enabled classes use "NetlistObject" as the base +class now. NetlistObject provides "set_property" to set or reset +a property and "property" to retrieve one. +Properties are persisted in L2N and LVSDB files and written to +layout shapes on "build_nets". +

    +Possibility to copy user property value. +
    • +

    • +
  • +Bugfix: #392
    +Layers "Style" sub-pane was malformed. +
    • +
  • +Enhancement: #394
    +Even bigger font sizes for rulers and labels for the 4k age: +Now there is "XLarge", "XXLarge" and "XXXLarge" as well. +
    • +
  • +Enhancement: #393
    +DRC syntax errors are now shown in their original code line +of the DRC script. +
    • +
  • +Bugfix: #400
    +Snap feature wasn't working for deep regions in certain use +cases. +
    • +
  • +Enhancement: new "scale_and_snap" methods
    +These methods allow scaling and snapping of layouts. Scaling +is supported by a rational factor. After scaling, snapping can +be applied to an integer grid. There are two incarnations. +Region#scale_and_snap (or Region#scaled_and_snapped): this is +a flat implementation which allows anisotropic scaling/snapping +as well. +And there is Layout#scale_and_snap which is a fully +hierarchical scale-and-snap feature. The latter does not support +anisotropic scaling/snapping, but works hierarchically without +opening gaps. It operates on a top cell and on all layers. +
    • +
  • +Enhancement: new Region#pull_* methods and DRC features
    +"pull_*" is a class of methods that allows rehierarchisation +of shapes. These methods act similar to "interacting", but +the other way around: instead of delivering interacting +shapes of the first argument, it will deliver shapes of +the second argument. For example, "a.pull_interacting(b)" +will deliver polygons of b which interact with polygons +of a. As a side effect, the polygons of b will be stored +hierarchically close to the polygons of a. This provides +a way to "re-hierarchise" layout. +The full class of methods and DRC functions involve: +Region#pull_interacting, Region#pull_inside, Region#pull_overlapping +and the same functions for DRC. +"pull_interacting" is also available for the Edges class +and edge layers in DRC. +
    • +
  • +Enhancement: Net tracer bug fix for heavily decomposed polygons
    +The net tracing feature now can operate on heavily decompose +polygons as well. Such layouts can be created by using a low +max. vertex count on GDS write. The problem were small +triangles with an area of 0.5 square DBU. +
    • +
  • +Enhancements: General fixes of deep DRC mode
    +Some inconsistencies with merged/raw mode have been +removed. Performance was enhanced in a few places. +Multithreaded mode now works more reliably. +
    • +
  • +Enhancements/bugfixes: various LVS improvements
    +The backtracking algorithm should work more reliable +in cases of ambiguities and floating nets or pins. +Performance should be better in some cases. +LVS script structure is less rigid now. "cheats" to +forcibly ignore hierarchy interactions for some +cells (useful for SRAM layout for example). +Still there is some work to do. +

    +Ruler properties editor: swap points and snap to object buttons +
    • +
  • +Enhancement: #343
    +Dockable bookmark window +
    • +
  • +Enhancement: Hierarchical mode for DRC ("deep" keyword)
    +DRC can be put into hierarchical mode with the "deep" +statement at the beginning of the file. +In hierarchical mode, most operations are performed +in a hierarchical fashion - i.e. trying to maintain +as much from the original hierarchy as possible. +
    • +
  • +Enhancements: Antenna checks for DRC
    +DRC now got an antenna check feature. Netlist extraction +is the basis for this feature. +
    • +
  • +Enhancement: Hierarchical mode in XOR tool and "strmxor"
    +The XOR tool and the "strmxor" buddy tool provide +switches to enable hierarchical mode. These options +are considered experimental currently as XOR between +two different layouts was not the implementation goal. +
    • +
  • +Enhancement: Netlist extraction
    +KLayout supports extraction of netlists from a layout. +This is the first step towards LVS. This feature includes +an infrastructure providing netlist data structures +(with Ruby/Python bindings), Netlist readers and writers +(Spice format), device recognition and a netlist browser. +
    • +
  • +Enhancement: LVS
    +The LVS feature is based on the netlist extraction capabilities. +It adds netlist vs. netlist compare and the corresponding +infrastructure. +LVS is a new script environment that is based on the DRC feature +and extends the DRC script language by LVS elements. +
    • +
  • +Enhancement: Command line option -mn to open netlist database +
    • +
  • +Enhancement: Net tracer "trace all nets"
    +Based on the netlist extraction feature, an alternative mode +for net tracing is provided. With "trace all nets", no a single +but all nets are traced at once. Probing then happens in the +final nets extracted rather than providing the seed shape. +"Trace all nets" operates in hierarchical mode and therefore +usually is faster and has a smaller memory footprint when +extracting huge nets such as power nets. +
    • +
  • +Enhancement: Library browser
    +The library browser is a dockable tool window which shows +all libraries installed. Use drag and drop to place a library +cell from the library browser in edit mode. +
    • +
  • +Enhancement: Layout query enhancements
    +Layout queries (aka "Search and replace") now allow specification +of Variables when using the script API. The performance of queries has been +enhanced in the case of cell tree recursion. +
    • +
  • +Enhancement: Gridline colors
    +The grid lines (or dots, depending on the style) can now be given +different colors for axes, grid lines and the ruler inset. +
    • +
  • +Enhancement: Multiple files on import
    +The "File/Import/Other files into current" feature now allows +importing multiple files into the current layout. +
    • +
  • +Enhancement: Python standalone module
    +KLayout supports production of standalone Python modules +which provide the same features than the "pya" module but +for use without the KLayout binary. If installed properly, +"import klayout" will pull in all modules. "import klayout.db" +will pull in the database part. +Deployment on PyPI is supported. +
    • +
  • +Enhancement: Modal help dialog from modal windows
    +When using Assistant links in the UI, the assistant now is shown +as a modal window when called from a modal dialog. Before, the +Assistant window wasn't usable in this case. +

    • +
  • +Bugfix: 8 bit indexed GIF images can be used for package icons now +
    • +
  • +Enhancement: Provide a way to specify the type of a macro
    +This feature is mainly useful for command line arguments. +If you run KLayout with "klayout -b -r myscript" +it will not be able to determine the type of macro without +a suffix. +You can now explicitly specify a certain type by +giving the suffix implicitly like: "klayout -b -r myscript[rb]" +This will read "myscript" but pretend it was "myscript.rb" +and execute it as Ruby script. +This feature is handy if you need to run a file with a +specific interpreter but cannot modify the file name. +
    • +
  • +Enhancement: Selection now shows PCell display names
    +Before, the internal name was shown for instances +
    • +
  • +Enhancement: There is an option in the View menu to show or hide markers
    +Markers may hide layout under them. With this feature you can +quickly disable all markers and the layout becomes visible. +

Features:

+ +
    +
  • +Enhancement: Compile option to use libcurl instead of QtNetwork
    +This workaround enables builds on the native CentOS6 +configuration with the package manager functional. +
    • +
  • +Enhancement: Pass label (text) layers through DRC script
    +The "labels" method now allows copying labels from a layer +to the output. +
    • +
  • +Enhancement: New "split" method for polygons
    +This method will fragment the polygons into two or more +smaller parts for reducing their vertex count. +
    • +
  • +Enhancement: New "dtrans" method for RecursiveShapeIterator
    +This method delivers the transformation in micron unit space +
    • +
  • +Enhancement: New "insert" methods for Shapes
    +Shapes can now insert from another Shapes container and +from a RecursiveShapeIterator. Possible applications are +fast flattening and fast region selection. +
    • +
  • +Enhancement: New method to generate RDB items from shapes
    +RdbItem#add_value from a shape, RdbDatabase#create_items +from a shapes container or recursive shape iterator and +RdbDatabase#create_item from a shape. +
    • +
  • +Enhancement: DXF and CIF "keep layer names"
    +If this option is set in the reader options, layer names +are not translated into GDS layer/datatype pairs. +Specifically a layer called "L5" for example is not +translated to 5/0 and to "L5D0" on output correspondingly. +The buddy script option is "--keep-layer-names". +
    • +
  • +Enhancement: DXF contour joining accuracy
    +On the DXF reader's options, a contour joining accuracy +can be specified. Small gaps smaller than this accuracy +will be closed when forming joined contours from edges. +The buddy script option is --dxf-contour-accuracy=value. +
    • +
  • +Bugfix: DXF display issue
    +In some cases, DXF cell instances did not trigger bounding +box update and the cells only got visible after save and +load. +
    • +
  • +Bugfix: XOR progress is more realistic
    +The progress is updated after the layer has been computed, +not before. +
    • +
  • +Bugfix: #117
    +DTrans#itype was broken. +
    • +
  • +Bugfix: #116
    +Fixed a polygon decomposition bug when writing GDS files +with big polygons with many holes. As a side effect, the +polygons with many holes computed by a NOT operation for +example are less complex and spikes in the cutlines are +avoided. +
    • +
  • +Bugfix: #115
    +Reader options were not persisted. +
    • +
  • +Bugfix: #114
    +Custom line styles not loaded from tech's layer properties +file. +
    • +
  • +Enhancement: #113
    +The XOR tool has an option now to heal result shapes which +cross tile boundaries. The result shape count of tiled +and non-tiled mode should basically be the same then. +
    • +
  • +Bugfix: #112

Features:

+ +
    +
  • +Enhancement: Menu customization
    +Menu items can be disabled or enabled now. The former +"Key Bindings" configuration page has been turned into +"Menu Customization". Check boxes allow enabling or +disabling of menu items.

    +with dark background. +
    • +
  • +Enhancements: Forward and backward navigation buttons in the main window.
    +These buttons jump to the previous or next display state: +zoom window, hierarchy depth, etc.. +
    • +
  • +Enhancements: A Package manager is provided. Packages are add-ons for
    +KLayout and can include macros, script libraries, fonts +for the TEXT PCell, technologies, DRC scripts etc. +Packages can be published on GitHub or any server +supporting WebDAV. After registering a package, users +can install or update packages with a few clicks. +For more information see %GITHUB%/wiki +or "About Packages" in the "Various Topics" area of the main +documentation. The package manager is found in the "Tools" +menu under "Manage Packages". +
    • +
  • +Enhancements: LEF/DEF reader: +
      +
    • Compatibility fixes with version 5.8
      • +
    • Regions and Groups are supported now
      • +

  • +Enhancement: DXR reader supports variable path widths now +
    • +
  • +Enhancement: XOR provides graphical progress +
    • +
  • +Enhancements: Libraries can be associated with a technology. Only libraries
    +associated with the selected technology are shown in the selection +dialog. +
    • +
  • +Enhancements: Overlapping instances are easier to select now (instance
    +selection cycling). +
    • +
  • +Enhancements: Many more methods in RBA/pya. For example: +
      +
    • Ability to directly insert "D" types (such as DBox +into layouts and cells.
      • +
    • RBA::RecursiveShapeIterator now supports complex (non-rectangular) +search regions
      • +
    • A more consistent type framework (consistent complex transformation +types, vectors)
      • +
    • More intuitive interface in certain objects (i.e. CellView, +LayerPropertiesNode, Annotation etc.). Changing an attribute +usually has an immediate effect on the respective property now +("live objects")
      • +
    • Hash functions for certain objects - Box, Edge, Trans, Polygon, +and other objects can be used as dictionary keys now.
      • +
    • New import methods for Region, EdgePairs and Edges
      • +
    • New features for LayerMapping and CellMapping
      • +

+ +

Features:

+ +
    +
  • +Enhancements: New method CellView#is_dirty?
    +This method indicates that a cell view needs saving +
    • +
  • +Bugfix: DEF reader was not able to read routing
    +Routed segments with vias plus continued wiring +were not read. Instead an error message was shown +saying "Invalid orientation specification" +
    • +
  • +Bugfix: Setting "technology-data" configuration property did not work
    +Reading or writing the "technology-data" configuration +property is the only way to access technology data from +a script. Hence it's important that this property can +be set. With this patch, "technology-data" can be set +to an XML string which has the same format than the +one stored within the configuration file. +
    • +
  • +Bugfix: Reader issues with some RVE files
    +The RVE reader could not read files with cell names +containing hyphens (like "A-B"). +
    • +
  • +Bugfix: Inplace operators are now working in Python too
    +For example "r1 += r2" was not working where r1 and r2 +were pya.Region objects. +
    • +
+ +

Version 0.24.9

 + +

Release date: 2016-11-28

+

Download links

+ +

Features:

+ +
    +
  • +Enhancements: The RBA::Region#smooth function was enhanced to
    +give somewhat better results +
    • +
  • +Enhancements: DXF's circle approximation can now also specified
    +through an "accuracy" parameter: if less than the number of +specified points is required to achieve the given accuracy, the +number is reduced accordingly. This also applies to the polygon +interpolation of spline and arc curves. +
    • +
  • +Enhancement: RBA integration now is compatible with Ruby 2.3
    +which allows building on Ubuntu 16 as well. +
    • +
  • +Enhancement: OASIS files with instance angles >360 were rejected
    +before. Now, this has turned into a warning. +
    • +
  • +Bugfix: DEF reader was failing to read MASK/via combinations. +
    • +
  • +Bugfix: The marker browser's "show only rules with errors" option
    +was enabled again on sorting of errors. +
    • +
  • +Bugfix: Using Layout objects for inputs didn't work +
    • +
  • +Bugfix: Copying Hierarchy treets containing PCell's made the
    +PCell's being turned into static cells. +
    • +
+ +

Version 0.24.8

 + +

Release date: 2016-06-19

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: XOR and different or big database units:
    +With tiling, XOR between two layouts with different database +units was still not working correctly. Also, when the database unit +was larger than 1nm, the XOR feature was dropping results sometimes +when tiling was on. +
    • +
  • +Enhancements: progress bar shown also for "-z" mode scripts:
    +The solution of 0.24.7 has been modified to avoid annoying +progress bar windows popping up in background-window mode: +Now, progress bar windows will only pop up if an active main +window is present. This will enable progress bars for scripts that +open their own main windows but still keep the application GUI-less +when the script does not do so. +
    • +
  • +Bugfix: Crash on empty panel:
    +When "New/Panel" is used a view without a layout is created. +An attempt to create layout on such panels crashed the application. +
    • +
  • +Bugfix: LEF reader now can read PIN statements including VIA +
    • +
  • +Bugfix: Polygon smoothing was not working properly in some cases
    +Previously the smoothing function was sometimes dropping vertexes +from the polygons. +Smoothing now does also guarantee not to exceed the given +distance. +
    • +
  • +Bugfix: Sorting cells by area now sorts cells by name as second choice
    +In the previous version, cells with identical area were +grouped but the order was arbitrary. Now the name is used as +the second-level sorting criterion which keeps such cells +sorted by name. +
    • +
+ +

Version 0.24.7

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: XOR and different database units:
    +With tiling, XOR between two layouts with different database +units was not working correctly. +
    • +
  • +Enhancements: progress bar shown also for "-z" mode scripts:
    +Scripts running in KLayout with the "-z" option (don't +show main window) were not experiencing progress reporting +before. Now a small modal window is shown during long-running +operations that indicates the progress and provides a Cancel +button to abort the operation. +
    • +
  • +Bugfix: Crash on using "Edit/Make cell":
    +This happened sometimes if the selected objects contained +instances. +
    • +
  • +Bugfix: Invalid behavior of paths with reflecting segments:
    +For example a path made of the points (0, 0), (0, 1000) +and (0, 0) had a reflecting segment which cause some +computations (for example the bounding box) to return +invalid results. +
    • +
+ +

Version 0.24.6

 + +

Release date: 2016-03-22

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: Early delete of plugin object when returning a new object
    +from PluginFactory#create_plugin. The returned object was +not held, so in Ruby the GC could destroy the object. This +could lead to crashes in applications employing the Plugin API. +
    • +
  • +Bugfix: It was possible to edit read-only macros.
    +For example, it was possible to enter new lines in macros +marked as read-only. However, these changes were not saved. +
    • +
  • +Bugfix: Shift+Tab not working in macro editor.
    +On some platforms, Shift+Tab was not working as expected. +This key combinations was supposed to left-shift a selected +block an undo indents. +
    • +
  • +Bugfix: Wrong scaling of layers when doing XOR's with layouts
    +with different database units. +This happened when the layouts had different layers and +"summarize missing layers" was disabled. +
    • +
  • +Bugfix: "Search & Replace" was not working properly if named
    +layers were present. Specifically the shape search was not +working due to an incorrectly formed query. +
    • +
  • +Bugfix: Sizing produced incorrect results in case of slowly
    +varying polygon contours. The effect was a contour with +spiky distortions where two "almost parallel" edges +connected. +
    • +
  • +Bugfix: The diff tool was not reporting differences correctly when
    +layers were present in one layout while they were not present +in the other. This happened specficially when "Summarize +missing layers" was disabled. +
    • +
  • +Enhancement: New context mode in marker browser: "Current or Any".
    +In this mode, the markers are displayed in the context of the +current cell. If that is not possible because the markers are +given for cells outside the cell tree of the current cell, the +fallback is to show the markers in the current cell as in "Any" +mode. +
    • +
  • +Enhancement: More consistent behaviour of cell and category filters
    +in the marker browser. For example, the category filter is +now also applied when selecting a node for a certain cell in +the cell branch and if nested categories are present, the +category filter is applied smarter - not just on each category. +
    • +
+ +

Version 0.24.5

 + +

Release date: 2016-02-26

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: Instance browser was messing up array instances sometimes.
    +After browsing instances, in some cases array instances got +messed up. This specifically happened with OASIS files. +
    • +
  • +Enhancement: Diff tool does not care about text alignment and
    +font properties unless in "exact" mode. Previously alignment +flags and font properties were compared in non-exact mode too +causing some confusion for example when comparing OASIS vs. +GDS. +
    • +
  • +Enhancement: XOR on layouts with different database units.
    +Previously, the XOR tool refused to run on layouts with +different database units. +
    • +
  • +Bugfix: The OASIS writer's S_TOP_CELL standard property now will
    +correctly use an "n-string" value in strict mode. +
    • +
  • +Bugfix: The OASIS writer bailed out on 1x1 cell arrays.
    +Now these pseudo arrays are written as single instances. +
    • +
  • +Bugfix: GUI type support for QVariant.
    +RBA/pya did not provide constructors for QVariant from +GUI types like QColor and QFont. These have been added now. +The corresponding conversion functions to QColor, QFont etc. +are provided as well. +
    • +
  • +Bugfix: Problems with QVariant constructor: some feature were not
    +usable. For example, a double value could not be passed to +the constructor. Disambiguators have been provided to solve +these issues. +
    • +
  • +Enhancement: Cell/Category filter for marker browser. The marker
    +browser now has a filter entry box to select specific cells +or categories. +
    • +
  • +Enhancement: Images are cached now for faster image update.
    +Specifically the "fit" image will be cached and if "fit" is +selected again, the image is restored rather quickly (provided +the window is not resized). The cache depth can be configured +in "Setup/Display/Optimization". +
    • +
  • +Bugfix: "Read all other layers" option in LEF/DEF reader was
    +potentially assigning GDS layers which have been defined in +the layer mapping. Now, layers used in the layer map for +targets are blocked and not used for automatic assignment. +
    • +
  • +Enhancement: The database unit can be configured now in LEF/DEF
    +import options. Previously it was fixed to 1 nm. +
    • +
  • +Bugfix: RBA::LayerProperties#id was not always unique as stated
    +by the documentation. Specifically not after a file was loaded. +
    • +
+ +

Version 0.24.4

 + +

Release date: 2015-12-17

+

Download links

+ +

Features:

+ +
    +
  • +Enhancement: Layer colors are iterated for named layers without
    +layer numbers as well. Such layers are created when reading +DXF files for example and all layers had the same color +initially. Now, these layers will be assigned different colors. +
    • +
  • +Bugfix: RBA::TilingProcess#threads was not working properly
    +when assigning a value of 1. +
    • +
  • +Bugfix: The perimeter computation now has changed to 64 bit numerics
    +reducing the risk of numerical overflow. In earlier versions, +the perimeter computation of integer type shapes (polygons, +boxes, regions) was performed with 32 bit length which is +not sufficient to represent total perimeters of full layouts. +
    • +
  • +Bugfix: The OASIS writer's S_TOP_CELL standard property now is
    +set to the correct value when using "Save cell as". +
    • +
  • +Bugfix: Some patches are provided for enhanced compatibility with
    +MacOS. One MacOS-only bug was related to a crash when re-registering +of PCell's while developing then. +
    • +
  • +Bugfix: PCell guiding shape parts could not be selected in partial
    +editing mode using a drawn selection box. +
    • +
  • +Enhancement: The color of the guiding shapes can now be configured
    +individually. +
    • +
  • +Bugfix: OASIS reader was not properly associating CELLNAME properties
    +with cells as the standard requires. Instead CELLNAME properties were +ignored. +
    • +
  • +Bugfix: Strict mode compatibility issues in OASIS writer:
    +File level PROPERTY records were not put right at the beginning of the file, +empty tables were not listed with 0 position, property value strings were +not referenced by ID and the property modal variables were referenced +sometimes after name records (specifically CELLNAME with standard +properties enabled). According to the specification, the name records +reset these variables so this is not correct. Other readers may report +errors for such files. +
    • +
  • +Enhancement: OASIS writer file size reduction. Now, the OASIS writer
    +will opimize the arrangement of cell array instances so that +modal variables can be used for a better compaction. +
    • +
  • +Enhancement: During script debugging now the Assistant window is active
    +even while the debugger is executing a script. The main window is +still inactive however to avoid fatal cross-interactions between +the debugger and the user interface. +
    • +
  • +Bugfix: The Python PCell sample was broken. +
    • +
  • +Bugfix: slowly bending paths have not been displayed correctly. +
    • +
  • +Bugfix: coordinates might have been swapped in the box properties
    +page when switching from local to absolute coordinates and +back. +
    • +
  • +Bugfix: certain ruler styles with independent x and y axis have not
    +been displayed properly when using a global transformation. +
    • +
  • +Enhancement: the performance of "Flatten cell" is enhanced significantly
    +in cases of many instances. +
    • +
  • +Bugfix: DRC output was producing new layers with an empty layer name
    +selector (no major issue, but confusing). +
    • +
+ +

Version 0.24.3

 + +

Release date: 2015-11-05

+

Download links

+ +

Features:

+ +
    +
  • +Enhancement: PYTHONPATH does not mess up the Windows installation any
    +longer. If you want to set the PYTHONPATH for KLayout, use +KLAYOUT_PYTHONPATH. +
    • +
  • +Bugfix: The oasis_write_std_properties attribute of RBA::SaveLayoutOptions
    +did not work as described. To maintain backward compatibility and +enable the cell bounding box feature, a new attribute called +oasis_write_cell_bounding_boxes was introduced. +
    • +
  • +Bugfix: "Hide all" only hides the top level layer properties, not the
    +members of layer groups. +
    • +
  • +Bugfix: S_BOUNDING_BOX standard properties now appear after CELLNAME
    +records in OASIS files as required by the OASIS specification. +
    • +
  • +Bugfix: The unintuitive behavior of the "Writer Options" has been changed.
    +Now, the writer options are applied to the saved layout always, not +just on the first save. Previously, the program remembered the options +and reused the previous options on following saves. This was quite +unintuitive since changing the properties did not necessarily affect +the way files were written. +
    • +
  • +Enhancement: The starting directory for files dialogs is the "Documents"
    +folder on Windows now. Not the current directory which is the +installation directory usually. +
    • +
  • +Bugfix: Signal names are property set for RBA::QListWidget and other
    +objects. This enables the use of "indexesChanged" signals and eliminates +Qt runtime warnings. +
    • +
  • +Bugfix: Library cells were not properly loaded again after reloading
    +a layout which used libraries which itself referred to other libraries. +
    • +
  • +Bugfix: The program crashed sometimes when using report databases with
    +properties. +
    • +
  • +Bugfix: Layers with a single box rendered wrong results in the DRC's
    +size function with strong undersize. The boxes did not vanish as +expected but instead were inverted. +
    • +
  • +Enhancement: The build now is compatible with Python 2.6. +
    • +
  • +Bugfix: Reading OASIS files in strict mode with cell names consisting
    +of a "$" character followed by an integer number (like "$1") sometimes +messed up the cells. +
    • +
  • +Bugfix: RBA::TilingProcessor could not be used both with tile size and
    +tile count set since setting the tile size was resetting the tile +count and vice versa. +
    • +
+ +

Version 0.24.2

 + +

Release date: 2015-10-02

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: Flip and Rotate function did not work as expected when the view
    +was descended into the hierarchy. +
    • +
  • +Enhancement: RBA::BrowserDialog now also accepts a parent parameter
    +which are important to better integrate such dialogs into the +application. +
    • +
  • +Bugfix/enhancement: "klayout_vo.exe" now is a pure viewer application
    +again. By calling this executable, the edit functions cannot be +enabled and the save functions are disabled as well. Under Linux, +renaming the binary to "klayout_vo" switches KLayout into this +mode as well. +
    • +
  • +Bugfix: The zoom and selection rectangle can now be dragged outside the
    +visible area and still define the zoom or selection rectangle. +
    • +
  • +Bugfix: expressions were not coercing floating-point values consistently:
    +The expression "to_i(2)+1.4" rendered 3 instead of 3.4 as expected. +The sum was treated as an integer sum because the first operand is +an integer. Now the integer is converted into a floating-point value +as expected. +
    • +
+ +

Version 0.24.1

 + +

Release date: 2015-08-26

+

Download links

+ +

Features:

+ +
    +
  • +Enhancement: switched to -O2 instead of -O3 to avoid issues with certain
    +gcc versions for which -O3 appears to be broken. +
    • +
  • +Bugfix: fixed a backward compatibility issue in scripting. Specifically
    +"view.each_object_selected { |s| s.shape }" will work again. +
    • +
  • +Bugfix: the layer matching algorithm in the .lyp file layer assignment
    +is compatible with the previous version again. This specifically applies +to "wildcard" specifications. In 0.24, named and unnamed layers were +considered different even if GDS layer and datatype numbers were identical. +The effect was that if a named layer was present, a .lyp file specification +without that name was not matching the named layer and with "add other layers" +the named layer was produced again. +
    • +
  • +Enhancement: "Apply all" in the object properties dialog behaves somewhat
    +more intuitive now. Specifically changing the path endcap styles now +works as expected. For the other properties, a choice was provided +between applying changes in a relative or absolute way. For example, +when the left edge of a box is changed, the left edges of all selected +boxes are shifted by the same amount in relative mode. In absolute mode, +the left edge will be set to the specified position for all selected boxes. +
    • +
  • +Bugfix: Python iterators will keep a reference to the source object now.
    +This avoids problems when fetching iterated properties (typically "each..." methods) +from short-living objects. +
    • +
  • +Bugfix: Python's StopIteration exception does no longer appear in the debugger
    +now. This is an exception used internally to mark the end of an iteration +sequence. +
    • +

Features:

+ +
    +
  • +Enhancement: Python support: Scripts and PCells can now be coded in Python as well. Python and Ruby
    +scripts may coexist in the same application and they can be debugged together. The macro +IDE features a Python tab in which Python scripts can be managed. +The language features of Python and Ruby are very similar, so the features of the +integration are highly comparable and easy to translate. The Python module +name is "pya". +
    • +
  • +Bugfix: When using a layer with special hierarchy level settings (i.e. #*), the ruler did not snap to that shapes. +
    • +
  • +Bugfix: Qt item ownership is now transferred on some methods. For example, "QTreeWidget#insertItem" now will
    +transfer ownership of the item to the tree widget. Hence, when the variable holding the item goes out of scope, +the tree item will not be destroyed. +
    • +
  • +Enhancement: The shape selection can now be manipulated through scripts (new LayoutView methods "object_selection=",
    +"select_object" etc.) +
    • +
  • +Enhancement: New edge vs. region operations are supported (edge AND region and edge MINUS region) +
    • +
  • +Enhancement: RBA/pya objects now in general feature a "_manage" and "_unmanage" method will allows releasing
    +the ownership over an object in cases where object lifetime control is important (specifically when passing +objects around in Qt applications). +

      • +
    +
    • +
  • +Enhancement: Qt API is aligned better with C++ Qt notation. Several bug fixes, new features and stability enhancements.
    +For example: +New: RBA::Qt::white or RBA::Qt::GlobalColor::white +Old: RBA::Qt_GlobalColor::white +
    • +
  • +Enhancement: the debugger can now be disabled in the macro editor IDE for enhanced
    +script execution performance with IDE window open and less interactions between +Qt code and Macro IDE +
    • +
  • +Bugfix: DRC crashed when outputting shapes to a layer that was used as an input
    +in further parts of the script but has been declared as input befor the layer +was output. +
    • +
  • +Bugfix: ".lyp wildcard replacement" now honors transformations as well +
    • +
  • +Bugfix: Gerber import issues fixed: Zero-diameter circular apertures moves are translated into lines,
    +Zero-length moves must not be clear for G1 and circular apertures. +
    • +
  • +Bugfix: The technology button now applies the technology even if the technology did not change. +
    • +
  • +Enhancement: Polygons with holes are better supported now (for example in partial editing). Such
    +polygons cannot be written to GDS or OASIS (they will be converted to ones without holes), but +they may be created in DRC scripts. +
    • +
  • +Bugfix: "Reload layout" now doesn't forget the technology that was attached to a layout. +
    • +
  • +Bugfix: Box side setters now behave more consistently in scripting. Before this fix, it was not possible to
    +assign the sides of a box this way: "b = Box::new; b.left = 100; b.right = 300". +
    • +
  • +Bugfix: recursive library references (library referencing itself indirectly) made the application
    +crash. +
    • +
  • +Bugfix: Subclass mapping sometimes failed in certain cases. This was particular annoying in Qt's event
    +handlers since "QKeyEvent" (or similar classes) only showed up "QEvent". +
    • +
  • +Enhancement: "Move selection to" function available in "Edit/Selection/Move To". With this function,
    +the selection (shapes are instances) can be moved to a specific position. You can specify the +reference point to use. For example the center of the bounding box. +
    • +
  • +Bugfix: Menu icon assignment was not working in some cases within scripts. +
    • +
  • +Bugfix: Readonly (global) macros could be edited but not saved. +
    • +
  • +Bugfix: Instances could be selected even if they had only invalid layers. +
    • +
  • +Enhancement: The application now features a crash handler. This handler gives some debugging information
    +about the crash which you can send together with a bug report. In some cases, the crash handler will +allow continuing to work with the application although it's highly advisable to save and close. +
    • +
  • +Bugfix: Registering plugins through the script's plugin API sometimes disabled view features. +
    • +
  • +Bugfix: The macro IDE is not automatically put in the foreground any more. This sometimes interfered with
    +modal dialogs shown from a macro. +
    • +
  • +Enhancement: The macro IDE now features watch expressions which are automatically evaluated when in a
    +breakpoint. +
    • +
  • +Enhancements: The "Save Layout" options are now separated from the save function. That means they can
    +be configured once and the dialog will not pop up always when saving. This way, "Save All" is provided +which will save all open files with the current options. +
    • +
  • +Enhancement: A "Close All" function to close all open layouts. +
    • +
  • +Enhancement: In scripted layout loads, multiple files can be loaded into the same layout object. In that
    +case, the content of the files are merged. This worked so far with GDS. Now this also works with OASIS. +
    • +
  • +Bugfix: OASIS int-typed properties now as written as such. Before, they have been written as strings. +
    • +
  • +Enhancement: sizing code and path to polygon translation now will better maintain 45-degree edges. +
    • +
  • +Enhancement: DRC support for edge/polygon booleans ("edges AND polygons" will select the edges inside the polygons,
    +"edges MINUS polygons" will remove the edges inside the polygons) +
    • +
  • +Enhancement: Global layout properties supported as well. Layout properties can be edited by selecting
    +"User Properties" in "File/Layout Properties". They are written to OASIS. Writing to GDS2 is optional since +that may create compatibility issues with other tools. +
    • +
  • +Enhancement: The OASIS writer will now produce some standard properties: "S_TOP_CELL", "S_BOUNDING_BOX",
    +"S_CELL_OFFSET", "S_MAX_SIGNED_INTEGER_WIDTH", "S_MAX_UNSIGNED_INTEGER_WIDTH" and "S_BOUNDING_BOXES_AVAILABLE". +
    • +
  • +Enhancement: User properties of cells are available in cell context menu too: this way there can be
    +browsed in non-editable mode too. +
    • +
  • +Enhancement: "Degenerated" polygons (one or two points) can be created in scripts now when using "raw" mode.
    +Such polygons are useful in the context of Minkowsky sums for example. +
    • +
  • +Bugfix: The application crashed when the macro currently running was deleted. +
    • +
  • +Enhancement: "Search & replace" now is available in viewer mode too, but without the ability to replace or
    +delete. +
    • +
  • +Enhancement: In menu paths, appending a "+" to the path means to add something after that item. +
    • +
  • +Bugfix: Guiding shapes are only selected if the PCell corresponding to them is visible. +
    • +
  • +Enhancement: there is a clearer indication now that 'Show layers without fill' is on. +
    • +
  • +Enhancement: a new mode is available in which PCell content can be selected too. When editing things inside
    +PCells however, PCell recomputation may revert these edits. +The mode is found in "File/Setup", "Application/Selection" page. +
    • +
  • +Enhancement: Edge set boolean operations have been too selective with respect to almost-parallel edges.
    +Now a tolerance is applied allowing edges to deviate by ~1 dbu. +
    • +
  • +Enhancement: Search & replace: texts, paths and boxes are exported into report databases.
    +Shapes and instances are shown in micron coordinates and as seen in top. +
    • +
  • +Enhancement: "Apply all" in properties dialogs: with this function, a specific change is applied to
    +all shapes or instances of the same class. For example a path width change is applied to all other selected +paths. The change will be applied smartly (hopefully), so that the intention of the change is preserved. +For example a left edge shift for a box will be turned into the same shift for all other selected boxes. +
    • +
  • +Enhancement: multiple categories can be selected in the marker browser now. +
    • +
  • +Enhancement: the instance properties page now shows the cell dimensions (which are not editable of course). +
    • +
  • +Enhancement: box property editing is less tedious - the left and right coordinates will now swap if the order
    +changes and the mode (width/center or coordinates) is maintained. +
    • +
  • +Enhancement: Report databases now support "tagged values" (values with a name) which are shown in the marker
    +list. The markers can be sorted by these values, provided they are string or numerical values. +RVE properties are read as tagged values. +

+ +

Features:

+ +
    +
  • +Bugfix: partial edit mode - a cell could be selected even if not visible
    +With the new version, the selection behavior of normal selection +and partial selection are somewhat more consistent. +
    • +
  • +Bugfix: The CIF reader was not able to read CIF files with line breaks
    +Commands with line breaks separating arguments were not read +correctly. +
    • +
  • +Bugfix: Printout now considers global transformation correctly
    +Previously, the global transformation was ignored on printout +and for screenshots. +
    • +
  • +Enhancement: Partial edit mode now also supports polygons with holes
    +Polygons with holes are rare since they cannot be represented +in GDS or OASIS files. But they can be generated in DRC scripts. +Now, such polygons can be edited in partial edit mode too. +
    • +
  • +Bugfix: LEF/DEF reader now correctly uses half the path width for path extension
    +Previously the default value was 0. +
    • +
  • +Bugfix: Library update was not working properly for OASIS reader
    +OASIS files with library references had as issue when updating +the library cells: cell deleted in the library were not deleted +in the layout. +
    • +
  • +Enhancement: Warning, when drawing on invisible layers
    +Previously there was not feedback: the shape was drawn, but not +visible. Now, a warning pops up when trying to draw on invisible +layers. This warning can be disabled. +
    • +
+ +

Version 0.23.10

 + +

Release date: 2015-03-07

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix/Enhancement: CIF compatibility. The reader was not fully
    +compatible with the specification. For example, lower-case +characters have not been ignored as specified. This has been +fixed among other compatibility issues. +
    • +
  • +Enhancement: The CIF writer now has an option to use blank characters
    +as x/y separator. Some tools apparently don't like comma +characters for separators (that is still the default). +
    • +
  • +Enhancement: The CIF writer now has an option to emit dummy cell
    +calls on top level to reference the top cells. The top-level +entity is unnamed and does not correspond to a cell. Despite +that some tools require these entities not to be empty and +hold dummy references to the real top cells at least. +
    • +
  • +Bugfix: Key bindings to default grid menu entries were not working +
    • +
  • +Bugfix: When a layer was deleted and a shape on that layer was
    +selected, the application crashed +
    • +
  • +Bugfix: Search and replace sometimes gave an internal error, for
    +example with the following query: +'with * do cell.name = "A" + cell.name' +
    • +
  • +Bugfix: Search and replace was crashing when trying to delete
    +instances. +
    • +
  • +Bugfix: Net tracer bug: the first selected shape was always taken as
    +a whole even if parts were disabled through boolean NOT +operations. +
    • +
  • +Bugfix: Net tracer was using the wrong origin when working in
    +"descend" mode. +
    • +
  • +Bugfix/Enhancement: The technology setup now features "read all" and
    +"add other layers" flags for the reader mapping table and +the layer properties. Before, the global flags were used +causing some confusion. With the new options the behavior +can be configured consistently. +
    • +
  • +Enhancement: The file dialogs now remember the file type chosen. +
    • +
  • +Bugfix: The application issues a error message when trying to
    +write very big images instead of crashing +
    • +
  • +Enhancement: Two new Ruby methods to write image files. These new
    +methods are LayoutView#save_image_with_options and LayoutView# +get_image_with_options. These methods allow configuration of +more features for the image generation like box to draw, +oversampling etc. +
    • +
  • +Enhancement: DXF reader now converts ATTDEF entities to texts too. +
    • +
  • +Bugfix: The application crashed when the top cell was deleted. +
    • +
+ +

Version 0.23.9

Release date: 2014-12-28

+

+ +

Features:

+ +
    +
  • +Bugfix: DEF reader: E and W pin orientation was swapped. +
    • +
  • +Bugfix: DEF reader: PIN definitions are read correctly even if
    +the PLACED statement comes before the LAYER statement. +
    • +
  • +Enhancement: LEF reader: deprecated keyword TOPOPSTACKONLY is
    +ignored for VIA statements now instead of giving an error. +
    • +
  • +Enhancement: DEF reader: the reader now is able to read BLOCKAGE
    +definitions. Currently, routing and placement blockages are +supported. The layers they appear on can be configured the +in the same fashion than for the other elements. +
    • +
  • +Bugfix: Typing in the Macro Editor was slow if many macros were
    +bound to menus. +
    • +
  • +Enhancement: GDS AREF's with pitches not a multiple of the database
    +unit are split into individual arrays rather than simply +rounding the pitch. The disadvantage of the rounding solution +was an accumulation of rounding errors over the array instances +leading to a substantial deviation from the target location. +
    • +
  • +Bugfix: Paths have sometimes not been displayed properly,
    +specifically paths with a small segment length and sharp bends. +
    • +
  • +Bugfix: DXF reader: bulges have not been ignored on the last vertex
    +of a non-closed POLYLINE as they should. +
    • +

    +broken +
    • +
  • +Bugfix: LEF/DEF reader: VIA PATTERN support was broken +
    • +
  • +Enhancement: LEF/DEF reader: Support for LEF/DEF Version 5.8 syntax +
    • +
  • +Bugfix: The Tab order of certain dialogs was weired +
    • +
  • +Bugfix: Multi-layout layer properties files in technology setups behaved
    +strangely. Now, the behavior of layout properties files (.lyp) is +the same in the technology context and the usual application context. +
    • +
+ +

Version 0.23.7

 + +

Release date: 2014-10-11

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: DRC was crashing on second run if it was overwriting an input file. +
    • +
  • +Bugfix: RBA::InputDialog::ask_double was not accepting negative numbers. +
    • +
  • +Bugfix: With a net highlighted in the net tracer, so view zoomed to show
    +the whole net if a layer was shown or hidden. +
    • +
  • +Bugfix: Ruler snapping was disabled for moderately complex hierarchies.
    +The threshold has been increased. Now snapping of the ruler to objects +also works for denser and more complex layouts. +
    • +
  • +Bugfix: Some signals were not available to Ruby (i.e. QIODevice signals). +
    • +
  • +Enhancement: When using "Hide empty layers", the layer list will scroll to
    +keep the selected layer visible (unless it is empty and hidden therefore). +
    • +
  • +Enhancement: A "split view" for the cell trees. When multiple layouts are
    +loaded in a panel, you can choose split view (right mouse in cell list, +check "Split View"). In split view, up to 5 cell trees are shown at the +same time. +
    • +

Release date: 2014-08-20

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: A DRC issue was fixed. Sometimes errors were reported too many times.
    +This happened for big polygons wrapping smaller ones. +
    • +
  • +Enhancement: Now, macro key bindings can be edited on the key binding page
    +of the setup dialog too if the macros are shown in the menu. +Before, those changes were reset when the program was closed. +
    • +
  • +Enhancement: The DXF reader now also considers thin (width = 0) POLYLINES
    +as mergable edge contributions in the "merge edge" modes if the +POLYLINES are closed ones too. +
    • +
  • +Bugfix: The float function in the OASIS writer was fixed.
    +This is a code cleanup, and did not have effect on functionality (yet). +
    • +
+ +

Version 0.23.5

 + +

Release date: 2014-07-04

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: DXF polyline mode could not be set in reader options in Ruby.
    +A value of 3 and 4 was not allowed. +
    • +
  • +Enhancement: CIRCLE AND ELLIPSE objects are treated as thin lines in DXF reader's
    +"merge edges" mode. Hence they participate in region formation. +
    • +
  • +Enhancement: A warning is displayed when an ambiguous keyboard shortcut is triggered +
    • +
  • +Bugfix: An assertion in the boolean processor was fixed. +
    • +
  • +Bugfix: The following command caused the program to crash on the Ruby console:
    +"require 'net/http'; uri = URI('xyz')". +
    • +
  • +Bugfix: The "cell" function in DRC scripts was creating a new cell if is was not existing
    +yet. In general, the DRC function is not supposed to change the layout's hierarchy. +
    • +
  • +Bugfix: The macro editor now can distinguish between the same file with different suffixes.
    +Before, "test.rb" and "test.lym" were not presented as different files. +
    • +
  • +Enhancement: The marker browser now indicates if the number of markers exceeds the
    +specified maximum and the list is shortened. +
    • +
  • +Bugfix: The "browser.rb" sample was not working any longer because of a backward
    +compatibility issue. +
    • +
+ +

Version 0.23.4

 + +

Release date: 2014-03-15

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: UTF8 encoding in XML was ignored - special characters have not been
    +read properly. This in particular caused issues in the .lym macro files +when UTF8 characters are employed. +
    • +
  • +Bugfix: Backward compatiblity issue: layout files with PCells written with 0.23
    +could not be read with 0.22 and vice versa. +
    • +
  • +Bugfix: Label text centering and right-alignment was not working propertly
    +with the default font. +
    • +
  • +Bugfix: A segmentation fault occuring when rerunning a PCell macro has been
    +fixed. +
    • +
  • +Bugfix: PCell layer parameters can be set to "no layer" now. This was possible
    +before, but caused some issues - i.e. creation of dead layers. +
    • +
+ +

Version 0.23.3

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: DRC bug fixed: "@x" notation was not working for layout, source and
    +target. +
    • +
  • +Bugfix: A boolean processor bug was fixed that cause an internal error in
    +some rare cases with certain edge configurations. +
    • +
  • +Bugfix: Image documentation was wrong about the offset meaning: it's the center,
    +not the lower left corner. +
    • +
  • +Bugfix: Layer table tab names were lost when sorting or regrouping a layer
    +list. +
    • +
  • +Enhancement: The net tracer now can be configured to auto-color the nets with
    +a set of predefined colors. 8 colors can be configured in the +configuration dialog or the net tracer setup page in the setup dialog. +
    • +
  • +Enhancement: The net tracer now has a "Redo" button which will trace all
    +nets in the list again using the original start and stop (for path +tracing) locations. +

    +processor receiver and multi-threaded tiling. +
    • +
  • +Bugfix: Layout move function was using database units instead of micron. +
    • +
  • +Bugfix: Search & replace markes where not shown in a reasonable context
    +for search in "All cells", instance markers are not shown +correctly. +
    • +
  • +Bugfix: DRC now also handles the case of different database units for
    +multiple inputs. The database unit of output files is now taken +from the input. +
    • +
  • +Enhancement: Search & replace layer selection combo boxes now show display
    +string +
    • +
  • +Enhancement: Unexpected elements are ignored in XML files. +
    • +
  • +Enhancement: Options are provided for making boolean operations not
    +optimize the "single empty input" case for XOR tool +and DRC (strict handling mode). +

Features:

+ +
    +
  • +Enhancement: Net tracer: Nets can now be colored individually. +
    • +
  • +Enhancement: The OASIS writer now uses CBLOCK compression also for tables. +
    • +
  • +Enhancement: Transparency is now supported for images (as a mask only - not a real
    +alpha channel, but close to). +
    • +
  • +Enhancement: The layer/datatype assignment for purely named layers originating from
    +DXF or CIF has changed. It's now no longer done when reading DXF or CIF but when +writing the file. This solution is more general and allows some level of control, +i.e. by scripts. +
    • +
  • +Enhancement: "http:..." URLs are now allowed as file names - such files are loaded
    +from the URL instead. Such URL's can be used from the command line or within scripts +for example. Drag and drop of HTTP URLs is also support. This allows dropping of +URLs from the browser into KLayout. +
    • +
  • +Enhancement: Menus have been rearranged:
    +The "Tools" menu was split into "Tools" and "Macros", "Verification" menu has been +resolved into the "Tools" menu. +
    • +
  • +Enhancement: New command line options are available:
    +"-nn" to load .lyt (technology file) on command line. "-b" for batch mode (implies some +batch-mode specific options), "-zz" for display-less applications. +
    • +
  • +Enhancement: "Adjust cell origin" now adjusts the cell in their parents as well (optional). +
    • +
  • +Enhancement: Cells can have properties now: Cells can now have user properties as well.
    +However, writing these properties to files is subject to some constraints. Cell +properties are fully supported on OASIS and optionally supported on GDS using +an extension feature. +
    • +
  • +Enhancement: Transformations are now available for whole layout (applied to all cells).
    +This is specifically useful for scaling layouts. +
    • +
  • +Enhancement: A function now is available to convert PCell's to normal (static) cells. +
    • +
  • +Enhancement: The printout now has a header and footer. +
    • +
  • +Enhancement: The XOR can now be confined to a region. +
    • +
  • +Enhancement: There is an option now to hide guiding shapes for PCell instances. +
    • +
  • +Enhancement: New option to pan/zoom or do nothing on paste - Option is in "Navigation/Zoom
    +and Pan" in setup dialog. +
    • +
  • +Enhancement: Cells can now be copied in "shallow copy" mode without creating copies of the
    +child cells. +
    • +
  • +Enhancement: A "Tap" function is provided now. The tap function selectes and changes to the
    +layer of the currently selected shape. New shapes will be put on that layer. +
    • +
  • +Enhancement: There now is a function to convert instance arrays to single instances. +
    • +
  • +Enhancement: The instantiation path of an object is now shown in the status bar. +
    • +
  • +Enhancement: An option is now provided for configuring the replacement character for
    +OASIS and GDS. The replacement character is used instead of illegal characters. +
    • +
  • +Enhancement: Some unicode support for texts in default font ("µ" now is available). +
    • +
  • +Enhancement: There is a GDS2 writer option now to eliminate zero-length paths. +
    • +
  • +Enhancement: There are new save options: disable or enable writing of PCell and library cell
    +contexts, drop hidden cells, keep instances even if cells are dropped. +
    • +
  • +Enhancement: Layers can now be made invalid. Invalid layers don't participate in selection or
    +snapping. +
    • +
  • +Enhancement: Multi-selection on 'open layout' allows to open many files at once. +
    • +
  • +Enhancement: DRC functionality: a rich DRC engine was integrated in the tool. The
    +implementation is flat, so performance is limited compared to hierarchical tools. A tiling +approach is available to distribute tasks on multiple CPU's to somewhat mitigate that issue. +
    • +
  • +Enhancement: Search and replace feature plus custom queries: the search & replace functionality
    +is just the tip of the iceberg. "custom queries" are a powerful feature to perform +queries and modifications using a SQL-like language. +
    • +
  • +Enhancement: Some enhancements on LEF/DEF import: i.e. proper default routing rule with octagon
    +ends implementedin DEF, NONDEFAULTRULES for LEF reader +
    • +
  • +Enhancement: Auto-import feature for technologies: technologies can now be imported from
    +the installation folder automatically. +
    • +
  • +Enhancement: RBA enhancements: Tiling processor, fill tool bindings, regions, edge collections,
    +edge pairs and edge pair collections, numerous new methods and classes. +
    • +
  • +Enhancement: More configuration options for macro IDE: stop on exception will ask whether to stop
    +in the debugger when an exception is thrown. The editor font can now be configured. +
    • +
  • +Enhancement: The diff tool now has an option to disable smart cell matching and enable
    +name-only cell matching. +
    • +
  • +Enhancement: cells can now be dragged and dropped from the cell list to the canvas. +
    • +
  • +Bugfix: Layout diff reported texts as different which are not. +
    • +
  • +Bugfix: Instance editor options problem fixed: magnification could not be edited in some cases. +
    • +
  • +Bugfix: DXF reader: anisotropic scaling of block deletes subcells of that block, error messages
    +on coordinate overflow. +
    • +
  • +Bugfix: OASIS output files were corrupt when edge objects were written. +
    • +
  • +Bugfix: Problems with boxes having odd width are solved now. +
    • +
  • +Bugfix: Close function - "Cancel" now works properly on the "which view to close" dialog. +
    • +
  • +Bugfix: Closing the main window while layouts are loaded crashed the application. +
    • +
  • +Bugfix: Net tracer did not work properly with OASIS in viewer mode. +
    • +
  • +Bugfix: Diff tool was not matching cells propertly in some cases +

+ +

Features:

+ +
    +
  • +Enhancement: "gds2" now is recognized as extension of GDS files. +
    • +
  • +Bugfix: CIF reader was broken in some cases. Layers have not been assigned properly
    +and sometimes, identical or no GDS layers were assigned. +
    • +
  • +Bugfix: RecursiveShapeIterator (RBA) had an issue when iterating shape arrays.
    +This was the case when working on OASIS files in viewer mode for example. +
    • +
  • +Bugfix: DEF reader had some issues (TAPER and RESISTANCE keywords have not been
    +supported properly). +
    • +
+ +

Version 0.22.7

 + +

Release date: 2013-03-22

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: The output mode in the XOR tool dialog was not shown properly. Instead of
    +"Report database", "Other layout" was shown etc. +
    • +
  • +Bugfix: When creating a third layout for output of the XOR tool, the database unit
    +was not set to the input layout's database unit. +
    • +
  • +Bugfix: Layout numbering was not done correctly when multiple layouts were loaded
    +with the same file name. +
    • +
  • +Bugfix: In viewer mode sometimes it was not possible to move to the next selected
    +item in the shape properties dialog. A message appeared saying "Shape array members +cannot be modified." +
    • +
  • +Enhancement: OASIS writer performance is significantly better now in cases where
    +shape compression is relevant. Also, shape arrays are maintained as such which +avoids repeated compression. +
    • +
  • +Bugfix: A drawing bug was fixed which caused shape arrays to disappear on certain
    +zoom levels. +
    • +
  • +Bugfix: "Add missing layers" now adds all existing layers, not just the ones
    +present in the currently selected cell also in viewer mode. +
    • +
+ +

Version 0.22.6

 + +

Release date: 2013-03-03

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: It was possible for example to add shapes to a PCell. This feature does
    +not make sense since PCell's are updated when required. In that case, changes +are lost. This feature has been disabled for PCell's. +
    • +
  • +Bugfix: RBA::Application#get_config was crashing in some cases (i.e. in -zz mode) +
    • +
  • +Bugfix: The "create cell variants" function was not working properly if a single
    +instance array was present for a cell. +
    • +
  • +Bugfix: The radius was limited too strictly for end segments for the ROUND_PATH
    +PCell of the Basic library. +
    • +
  • +Enhancement: Some additional RBA methods have been enabled which disambiguate
    +various constructors for Qt objects (i.e RBA::QVariant#new_i allows to create +a variant with "int" type) +
    • +
  • +Bugfix: the Ruby-less build was broken. +
    • +
  • +Bugfix: Copy & paste was not working for the layer list. This is an effect of the
    +modified key handling in KLayout 0.22. New menu functions are provided in the layer +list's context menu to resolve the ambiguities involved in that feature. +These menu functions allow to copy, cut and paste parts of the layer list to other +windows or tabs. +
    • +
  • +Bugfix: PCell's are now cleared before the production method is called. +
    • +
  • +Enhancement: OASIS layer names are also recognized if the LAYERNAME record
    +appears after the layout's body. +
    • +
  • +Bugfix: in previous versions it could happen that the layout panels got
    +locked and it was no longer possible to switch between different tabs. +
    • +
  • +Bugfix: a potential crash in the drawing engine was fixed. +
    • +
+ +

Version 0.22.5

 + +

Release date: 2013-02-02

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: Layer properties file in technology definitions can be given as relative path
    +in which case KLayout uses the base path +
    • +
  • +Enhancement: Windows installer now provides a useful default installation path when
    +started as non-administrator. +
    • +
  • +Bugfix: GDS reader: a false warning was issued sometimes indicating that an
    +AREF might be off-grid. +
    • +
  • +Bugfix: Fixed build for MacOS and some Linux distributions. +
    • +
  • +Bugfix: Fixed a crash that happened when KLayout was closed while a instance
    +property form was still open. +
    • +
  • +Enhancement: PCell names are now shown in the status bar +
    • +
  • +Bugfix: Fixed a crash that happened when a macro was run that was already closed. +
    • +
  • +Bugfix: MRU list for macro editor's console was getting huge when the macro editor
    +was closed and opened again in the same session. +
    • +
  • +RBA bugfixes: "destroyed?" was not working properly in some cases. Infinite
    +recursion happened for for PCell implementation without "get_layers". +
    • +
  • +Enhancement: Better error messages for RBA including class and method names. +
    • +
  • +Bugfix: PCell implementation issue. Some methods were passed a deep copy
    +of the layout object which first created a potential performance issue and +second made it impossible to modify the layout. +
    • +
  • +Enhancement: DXF writer now provides a header which enables some tools to
    +read the generated DXF files. +
    • +
  • +Bugfix: DXF reader: degenerated polygons for HATCH objects don't cause an
    +assertion now. +
    • +
+ +

Version 0.22.4

 + +

Release date: 2012-12-30

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: a drawing problem was fixed which created invalid images in certain
    +cases. +
    • +
  • +Bugfix: multi-tab .lyp files could not be used correctly as default layer
    +properties files. +
    • +
  • +Bugfix: the macro IDE crashed sometimes when adding a new location. +
    • +
  • +Bugfix: the application crashed when the net tracer window was open and a new
    +layout was loaded into the same panel. +
    • +
  • +Bugfix: a memory leak was happening when a boolean operation (in particular
    +inside the XOR tool) was cancelled. +
    • +
  • +Bugfix: when inserting an instance using the lower left corner of the bounding
    +box as the reference point, rotations have not been handled correctly. +
    • +
  • +Enhancement: the "detailed" view of a net's properties in the net tracer now
    +reports area and perimeter of the net's shapes (only available for nets up to +~2000 shapes to avoid timeouts on computation). Thanks to Peter for providing +the raw version of that code. +
    • +
  • +DXF reader enhancements:
    +Support for "999" comment records. DIMENSION and SPLINE entities are supported +now to some extent. "fit" formatting of TEXT objects supported now. +Holes are correctly formed now from multiple POLYLINE/LINE items when combining +them into polygons. +
    • +
  • +DXF writer: HATCH entries are written in a compatible way now. Text formatting
    +flags are fixed (top and bottom formatting was swapped). +
    • +
+ +

Version 0.22.3

 + +

Release date: 2012-11-25

+

Download links

+ +

Features:

+ +
    +
  • +Bugfix: a segmentation fault sometimes happened in the drawing engine +
    • +
  • +DXF reader enhancements:
    +Anisotropic scaling of instances is supported. LWPOLYLINES with both common and +variable width are handled more gracefully. Closed polylines produce closed shapes +now, not closed paths. +
    • +
  • +Selecting of instances with non-orthogonal transformations is easier now +
    • +
  • +The local config files now override the global one again like this was in 0.21.x. +
    • +
  • +A compile problem with older gcc's (namely gcc 4.4) was fixed. +
    • +
  • +Selection of cells in the cell tree now has been fixed (before that sometimes
    +cells were selected in addition to current ones instead of being the only +one selected). +
    • +
  • +The RVE DB reader was enhanced to read error waivers and certain new forms of the
    +RVE file. +
    • +
  • +The align operation now works also if there is not a primary and secondary
    +selection (i.e. selection by box) +
    • +
  • +"Layer pollution" does not happen when instantiating a PCell or library cell
    +which is instantiated in another panel +
    • +
  • +PCell layer parameters now can be set to any layer which is present in the
    +layer list, not just the ones which are created already in the database +
    • +
  • +The round corners function has been fixed for certain cases. In particular
    +the limitations are less strict (for example it is possible now to create +a donut from a square with a hole). Changing of the radius later now works +more reliably. +
    • +
  • +"Shallow copy mode" now works again for copy & paste of instances. Previously
    +instances were always copies in deep copy mode which creates new cells. +
    • +
  • +Move of partial selection now works like the move function for other objects:
    +select a subset of edges, click on them to start dragging and click again to +drop them. +
    • +
  • +Arrow keys don't interfere with move by mouse mode any longer. Previously using
    +the arrow keys while moving objects with the mouse had strange effects. +
    • +
+ +

Version 0.22.2

 + +

Release date: 2012-11-01

+

Download links

+ +

Features:

+ +
    +
  • +Copy & and paste of PCell or library instances across layouts did not work
    +Instead, the cell was duplicated, but it's no longer a PCell or library cell. +
    • +
  • +"klayout -v" was segmentation faults
    +The -v option is supposed to print the version number. After printing it, +the executable terminates with a segmentation fault. +
    • +
  • +'Real' unicode file names could not be used
    +Using Unicode filenames (i.e. Chinese) file names did not work properly. +In particular these files were not opened on Windows. Unicode file names were +not recorded properly in the "recently used" list. +In version 0.22.2, unicode files names can be used in all places on Windows +and Linux. +
    • +
  • +Some LEF import issues solved
    +The outline layer was not always generated correctly. Pin labels were not generated +on pin shapes for LEF import. +
    • +
  • +KLayout was crashing on exit when the clipboard contained something
    +The application issued a segmentation fault on exit (or "is not working" on Windows) +when the clipboard contained data. +
    • +
  • +Ruby debugger crashed in some cases
    +In some cases (i.e. breakpoint in a widget callback) the debugger crashed with a +"Stack level too deep" message. +
    • +
  • +Instances of leaf cells were always copied "flat" to another layout
    +There was no way to copy the instance plus cells before this was fixed. +
    • +
  • +Sometimes PCell variants remain as top level cells
    +If the Instance function was cancelled and a PCell was active, a new top cell remained +which held the PCell that was about to be placed. These cells could be deleted manually, +but that may be annoying. +
    • +
  • +Help index cache was growing large in some cases
    +When switching between versions, the help index that KLayout creates once grew larger +every time a new program version was used. This increased startup times of the program. +
    • +
  • +An "abs" function was missing expressions +
    • +
  • +Experimental support for 64bit coordinates is provided.
    +To enable 64bit coordinates, use "-with-64bit-coord" on the build script. This feature +requires gcc >= 4.4 and a 64bit platform. 64bit coordinate support is "experimental" +because of some known issues (i.e. it is possible to write corrupt GDS files with such large +coordinates). OASIS on the other hand supports 64bit coordinates. +
    • +

Version 0.22.1

 + +

Release date: 2012-10-09

+

Download links

+ +

Features:

+ +
    +
  • +Edit/Select/Disable All was not working
    +This function was supposed to disable all selectable items. Instead, an internal +error message was issued. +
    • +
  • +Build problems with gcc 4.0 were solved +
    • +
  • +GDS text size as based on micron instead of user units
    +Because of this the text object size were not be correct if the user unit was not micron. +
    • +
  • +Arrow keys behaved differently
    +This had annoying effects if one was used to a particular behavior. The operation of the +arrow keys was restored in some places but still moving with the keys in move mode is +possible. +
    • +
  • +-z option worked differently
    +"-z" is not a true "non-GUI" mode, in which no XServer connection is made on +Linux. The advantage of this is that KLayout can be used as a engine on display-less +servers. In 0.22, some user-interface related objects were not available in Ruby code. +Some scripts depending on MainWindow or LayoutView objects were not working +because these objects are no longer available. In 0.22.1 the original behavior of "-z" +was restored and instead, "-zz" was implemented as a different, true display-less mode +
    • +
  • +KLayout was crashing when using custom key bindings on some platforms
    +On some platforms, apparently Linux and recent Qt versions, KLayout crashed when +custom key bindings are defined and the respective key is pressed. +
    • +
  • +Some issues with the macro tree solved
    +Drag & drop was not working correctly within the macro tree on Windows. KLayout +crashed when trying to open a macro file that is not writable. +
    • +

    • +
  • +A basic library is provided adding text generation for example to KLayout.
    +See About The Basic Library for details. +
    • +
  • +The net tracer now allows to use layer combinations (derived by boolean operations)
    +for the conductive and via layers. See The Net Tracing Feature for details. +
    • +
  • +A technology management is integrated into Klayout.
    +That allows to switch various settings depending on the chosen technology. +See About Technology Management for details about this feature. +
    • +
  • +The drawing can now be rotated or flipped without having to modify the layout.
    +This function can be found in the "Display" menu under "Global Transformation". +
    • +
  • +The "background" combination mode allows to erase parts of existing shapes or
    +add new parts to existing shapes. The background combination mode is available +as a new drop-down button in the toolbar. +
    • +
  • +A "cell variant" generation function simplifies hiearchical editing.
    +See Create Cell Variants for details about this feature. +
    • +
  • +General performance improvement of the render.
    +This has been achieved by bitmap caching of cells and various optimisation measures. +
    • +
  • +Images now can be aligned with a layout using landmark points.
    +The possible image transformations now include shear and perspective distortions. +See Using Landmarks To Align Images +
    • +
  • +Images can now be stacked and moved to the bottom and to the top.
    +The configuration now is stored along with additional configuration data +(i.e. libraries) in a per-user directory in "~/.klayout" on Linux and in the application +data path on Windows. The configuration file now is found there and is called "klayoutrc". +New locations can be added using $KLAYOUT_PATH. +
    • +
  • +The database unit of the layout can be changed now in the layout properties page
    +(menu: "File/Layout Properties"). +
    • +
  • +Most numeric input boxes now accept formulas,
    +i.e. "1254+3221" instead of a single value. +
    • +
  • +By clicking a on single point multiple times you can now cycle the selection through all objects below the point. +
    • +
  • +Layers can be copied (menu: "Edit/Layer/Copy Layer"). +
    • +
  • +The selection can be duplicated (menu: "Edit/Duplicate" or Ctrl+B). +
    • +
  • +The size of the default font can now be adjusted (choose between small (current),
    +medium and large on the Display/General page of the setup dialog). +
    • +
  • +The number of points used for circle interpolation can now be adjusted
    +on the Application/Circles page of the setup dialog. +
    • +
  • +Some changes to make the user interface more consistent, i.e. "Synchonized views"
    +has been moved to "Display" where most users where expecting it to be. +
    • +
  • +The selection now can be moved with the cursor keys in move mode. +
    • +
  • +The cell selection dialog allows to specify glob pattern wildcards in the filter box now. +
    • +
  • +OASIS CBLOCK compression and strict mode writing is supported now. +
    • +
  • +Multiple cells now can be selected in the cell tree. Some functions operate on that set (i.e. delete, copy, hide). +
    • +
  • +KLayout now has a LEF/Def import feature. See About LEF/DEF Import for details. +
    • +
  • +This feature is somewhat experimental. Feedback is welcome about that feature.
    +Solved bugs: +
    • +
  • +Edit/Select/Disable All not working
    +This function is supposed to disable all selectable items. Instead, an internal error message is issued. +
    • +
  • +Build problems with gcc 4.0 +
    • +
  • +GDS text size is based on micron instead of user units
    +Because of this the text object size may not be correct if the user unit is not micron. +
    • +
  • +Arrow keys may behave differently
    +This can be annoying effects if you are used to a particular behavior. On the other hand, moving with +the arrow keys now is possible in move mode. +
    • +
  • +-z option works differently
    +"-z" not is a true "non-GUI" mode, in which no XServer connection is made on Linux. The advantage of this +is that KLayout can be used as a engine on display-less servers. But some scripts depending on MainWindow or +LayoutView objects will not work because these objects are no longer available. The solution will be to +restore the original behavior of "-z" and implement a different, true display-less mode (i.e. "-zz"). +
    • +
  • +Crash when using custom key bindings on some platforms
    +On some platforms, apparently Linux and recent Qt versions, KLayout crashes when custom key bindings +are defined and the respective key is pressed. +
    • +
  • +Issues with the macro tree
    +Drag & drop does not work correctly within the macro tree on Windows. KLayout crashes when trying to +open a macro file that is not writable. +

Features:

+ +
    +
  • +GDS format readers and writers now support time stamps: by default, the
    +current time is written to the files. This option can be turned off in the +"Save Layout Options" to simplify comparison of binary files for example. +In addition, the timestamp of the BGNLIB record is read and displayed in the +"Layout Properties" page. +

  • +Instances are not selected if the cell does not contain shapes in visible layers. +
    • +
  • +Marker browser does now work correctly when layer view transformations are present. +
    • +
  • +DXF reader enhancements: read LAYER table and assign GDS layers in that order,
    +except for layer which got a layer name through their name (i.e. L1D100). +Bugfix: don't suppress INSERT's if the layer is not mapped. Write TEXT and +MTEXT correctly (multi-line support, small chunks for MTEXT, character alignment). +New option: keep all cells for DXF reader. Added elliptic interpolation edge type +(not really tested yet). HATCH objects with bulges and various edge types are +implemented now. MTEXT supported now. New option: convert text to polygon for +unicode support. +
    • +
  • +Changed default sorting of layers: always sort by layer number first, even if there
    +is a name. If there is no layer number, sort by name. +

+

Download links

+ +

Features:

+ +
    +
  • +Support for DXF format (reading and writing).
    +ASCII and binary format are supported. There is an open issue how to +represent layouts with multiple top cells. Currently, the ENTITY section +is always empty and all cells are put into BLOCKS sections. DXF units +will be micron and the database unit must be selected manually when +layouts are read. +
    • +
  • +Support for CIF format (reading and writing).
    +There is an open issue how to deal with paths. By default, CIF states +that paths are supposed to have round ends. Obviously that interpretation +is not commonly used. Options are provided which control how path objects +are read and written. +
    • +
  • +Tabs for the layer panel. This feature is explained here. +
    • +
  • +Flat cell list and cell list sorting modes. The feature is explained here. +
    • +
  • +Dockable tool boxes.
    +Layer list, cell list, layer toolbox and navigator are now dockable and +can be dragged to another location, torn off the main window or closed +with Qt's standard dockable window controls. The position and the state +of the dockable windows is saved in the settings and session files. +
    • +
  • +A ruler embedded in the background image.
    +Now, a small ruler is embedded into the background which shows the +dimension scale similar to a map. It can be disabled in the setup dialog +on the "Display/Background" page. +
    • +
  • +Image quality enhancement by oversampling. The feature is explained here. +
    • +
  • +The "Diff" tool. The Diff tool produces a marker database containing a
    +description of the differences. A detailed description can be found here. +
    • +
  • +Snapping to objects is provided as an option for edit mode. In this mode,
    +the mouse snaps to vertices and edges of visible objects. This mode can +be enabled with the "Objects" checkbox on the "Editor Options" page (F3 +key or "Edit/Editor Options" menu). +
    • +
  • +The reference point for the placement of instances now is the lower left
    +point of the placed cell's bounding box, not the origin. +
    • +
  • +Dialog geometry persistent now.
    +Marker, shape and instance browsers now save their geometries and +splitter pane configurations when the application exits. +
    • +
  • +Instance placement now uses bbox origin, not cell origin.
    +This simplifies placement of cells with their origin not aligned with +the content. +
    • +
  • +Fill (tiling) tool. The tool is found in "Edit/Utilities/Fill Tool". A
    +detailed description can be found here. +
    • +
  • +In some places, particular in the ruler display string, expressions can
    +be used. For rulers, the previous display string placeholder scheme is +replaced by the more powerful expression expansion scheme (see Ruler +properties for details). +
    • +
  • +Build support for VC++ and Visual Studio 2010. The Windows 64bit build
    +now is based on that environment. Note: Visual Studio 2010 no longer +supports Windows 2000. To use KLayout on Windows 2000, a legacy build +based on MinGW is provided. +

    +
  • +Import option for Gerber PCB data ("File/Import" menu entry). Details
    +about this function can be found in the Importing Gerber PCB files +section in the advanced features manual. +
    • +
  • +A function to import another stream file into the current file.
    +This avoids having to use copy & paste and provides a couple of nice +options. Details about this function can be found in the Importing other +layout files section in the advanced features manual. +
    • +
  • +A simple XOR tool providing a flat XOR between two layouts. A tolerance
    +can be set to suppress small deviations. A tiling option is provided to +reduce memory requirements for large layouts. The flat approach probably +limits the application to "almost flat", small to medium sized layouts. +Details about this function can be found in the The XOR tool section in +the advanced features manual. +
    • +
  • +A net tracing tool to trace single nets of conductive layers connected
    +through via shapes. The function is intended for extracting single small +nets and it's not performance optimized for the case of huge power nets. +Details about this function can be found in the The net tracing feature +section in the advanced features manual. +
    • +
  • +A navigator window that shows current view's rectangle and allows to
    +control the rectangle by dragging or resizing it. +
    • +
  • +Multi threading support for drawing increases the drawing performance on
    +multi-core CPU's by rendering different layers on different CPU's. The +number of threads to use can be set in the setup dialog in the "Display" +group under "Optimizations". By default, a single thread is used. +
    • +
  • +"Make array" method ("Edit/Selection" menu) to multiply the selection
    +into an array arrangement. +
    • +
  • +A function to add a layout already loaded to a view ("File/Pull In
    +Other Layout"). +
    • +
  • +A function to scan a layer's geometry and create a marker database from
    +that. The menu function is found in the "Tools/Verification" menu. It +will scan all selected layers either flat or hierarchical and create a +marker database containing the shapes as markers. +
    • +
  • +Layer mapping on input: the reader options now allow to specify a
    +mapping together with a layer specification. In addition to specifying +the layers to read, a target can be given which specifies which layer +the shapes will be stored under (See "Reader Options" dialog found in +the "File" menu). +
    • +
  • +A couple of new display options:
    +o Abstract mode (shows only the outer interfacing shapes of child cells. +o Child hierarchy level layout can be configured to be shown in different +brightness, hollow fill or static neutral color to differentiate top +level from bottom level layout. +o Enhancements for the hierarchy level specifications in the layer source +notation. +
    • +
  • +A log viewer is provided to catch warning messages. The menu entry to open
    +the log viewer is found in the "File" menu. +
    • +
  • +The setup dialog has been reorganized to make room for more property pages. +
    • +
  • +Instances now show the cell's content when being moved instead just a
    +rectangle. This feature can be disabled. +
    • +
  • +Various usability enhancements (i.e. mouse cursor now shows activity,
    +status bar shows short shape statistics etc.). +
    • +
  • +An option to not write empty cells. +
    • +
  • +Support for missing cells in the input layout: those cells get marked and
    +are not produced in the output unless they have received content. That +allows to load and save layouts with missing cells without producing empty +cells for those missing cells. +
    • +
  • +Some new functions in the layer list context menu ("Show All", "Hide All",
    +"Show Only Selected"). +
    • +
  • +Various bug fixes (i.e. for clip function). +
    • +
  • +A couple of new RBA methods. +

  • +Images: it is possible now to load image files (JPG, GIF, TIFF etc.) and
    +display them below the drawn layout. The display of the images can be +adjusted in many ways, i.e. placement, scaling, rotation, mirroring, +color/contrast/brightness adjustments and false color mapping for gray +level images. Images are fully supported by RBA. The feature is described +in detail in Adding images. +
    • +
  • +Marker browser: the marker browser is based on the report database (RDB).
    +This is a new concept that has been introduced as a container for report +items, in particular marker objects but also for a number of additional +annotations including screenshots for documentation. An import of Calibre +DRC databases is provided. The RDB is fully supported by RBA. +The feature is described in detail in The marker browser. +
    • +
  • +Some enhancements for the layer views: invisible layers are now shown
    +differently in a "collapsed" way. Thus, the layer's colors and styles are +still recognizable. The new features are described in detail in Telling +used from unused layers. +
    • +
  • +In the layer list, unused layers can now be hidden and layers without
    +shapes in view can be marked unused or hidden. The normal mode of marking +layers unused when the cell does not contain any shapes at all is still +available. Both modes are available as checkable items in the layer list's +context menu. +
    • +
  • +A "View" menu has been added with fast access to certain display options,
    +i.e. turn grid on an off. A number of default grids can be defined for +quick selection in the "View" menu. On request, the tool bar can now be +hidden as well as the layer and hierarchy lists. +
    • +
  • +A key binding editor is provided. This way, all menu functions can be
    +assigned arbitrary key shortcuts in a more comfortable ways. +
    • +
  • +The mid mouse button can be used to pan (drag) the view window now. +

Features:

+ +
    +
  • +Some bugfixes (for a list of fixed bugs see Known bugs in version 0.17.2). +
    • +
  • +Added support for the GDS2 text format. This is a contribution by
    +Romain Gauci from Oscillated Recall Technology (http://www.or-tech.co.jp). +
    • +
  • +Session persistence: sessions (files, layers, bookmarks, setup) can be
    +saved and restored. Details for this feature can be found here. +
    • +
  • +Reader options can be specified in a dialog now (File menu). Some GDS2
    +specific reader options are available: allow multi XY, allow big records +and several box record handling modes. Details for this feature can be +found here. +
    • +
  • +GDS2 specific writer options (max vertex option, multi XY record option,
    +max cell name length). +
    • +
  • +The stipple palette now is editable. A corresponding page has been added
    +in the setup dialog. +
    • +
  • +Flatten cell function. A cell can be flattened which will remove the cell
    +and all the subcells unless not specified otherwise. This function can be +found in the cell's context menu. Details for this feature can be found +here. +
    • +
  • +The 'Make Cell' operation provides a nice origin now. Before, the origin
    +of the new cell was far off sometimes. +
    • +
  • +Accept drag & drop of .lyb, .lys, .lyp, .rb, .rbm and layout files. +
    • +
  • +Switched to standard file dialogs where this has not been the case yet.
    +In particular on the Windows platform, the application will behave somewhat +more consistent. +
    • +
  • +Added an option to draw only border instances of arrays. This option can be
    +found on the 'Misc.' tab of the setup dialog. +
    • +
  • +Added the capability to define global ruby modules using the ".rbm"
    +extension and putting them into the installation directory. +
    • +
  • +Full cell copy & paste functions can now be found in hierarchy panel
    +context menu. +
    • +
  • +Enhancement of grid snapping in partial mode. Before, a offgrid vertex could
    +not be brought on-grid because movement was confined to grid steps. +
    • +
  • +Number of points for polygons is shown now in the polygon property dialog. +
    • +
  • +Hole resolution for GDS2 and OASIS writer. Before, polygons with holes
    +(which can be produced by scripts) were rejected. +
    • +
  • +Some bugfixes for clip, using booleans for clip to overcome some problems
    +with hole connectors and spikes - slow but safe.. +
    • +
  • +'#' character is not longer used when creating cell variants - instead '$'
    +is used to enhance the compatibility with other tools which do not allow +the "#" character as part of cell names. +
    • +
  • +On paste, a 'fit selection' is done to show what has been pasted. +
    • +
  • +Mouse wheel mode is configurable now (shift/ctrl modifier behaviour).
    +The 'alternative mode' can be found on the 'Misc.' tab in the setup dialog. +
    • +
  • +Option to clear all rulers when cell is changed. This option can be found
    +on the 'Misc.' tab in the setup dialog in the 'On Cell Change' group. +RBA enhancements: +
    • +
  • +A new class: ICplxTrans and related functions. +
    • +
  • +A recursive shape iterator simplifies hierarchical region queries and
    +"as if flat" traversal of cells. +
    • +
  • +Polygon: hull and hole can be assigned now, compress method, point accessors. +
    • +
  • +The installation path now is available. +
    • +
  • +Added a method which allows to display a message in the status bar. +
    • +
  • +The transient selection now is available for RBA procedures. +
    • +
  • +New events are generated if selection and transient selection changes. +
    • +
  • +Added a generic assign method for copyable objects. +
    • +
  • +Added new classes 'LayerMap' and 'LoadLayoutOptions'. +
    • +
  • +Added two 'read' methods to Layout class. +
    • +
  • +Added a couple of methods to 'LayerInfo' (constructors, compare, ...). +
    • +
  • +Added a 'load_layout' method to LayoutView. +
    • +
  • +Added more cm_* methods to MainWindow. +

Features:

+ +
    +
  • +Some new editing capabilities: flatten, make cell, clear layer and a clip
    +function. +
    • +
  • +Some RBA extensions, in particular the ability to modify layout by deleting
    +shapes and instances, replacing and transforming them, changing property +handles etc. +
    • +
  • +Support for global preset of configuration (through a file called "layviewrc"
    +beside the executable binary) and a global RBA initialisation file (a file +called "rbainit" beside the executable binary). +
    • +
  • +Transient selection: indicates by a faint selection marker what object is
    +below the mouse (can be disabled). +
    • +
  • +The layer specification (layer, datatype, name) can be now be edited which
    +allows to move a complete layer to a different one. +
    • +
  • +Undo buffering can now be disabled on the command line with the '-i' option.
    +This saves the memory otherwise required for storing the replay information. +
    • +
  • +Directional constraints can be modified by using the Shift and Ctrl modifiers
    +on various operations such as rulers, movement, drawing etc. +
    • +
  • +Now there is a 'most recently used' list ("Open Recent" in the "File" menu)
    +which shows the last layouts opened for easy re-opening. +
    • +
  • +Reduced memory requirements for particular OASIS constructs (random repetitions) +
    • +
  • +The instance browser now has a "Choose cell" button where the cell can be
    +chosen whose instances will be presented. +
    • +
  • +For most editing operations, the status bar will now indicate more detailed
    +information such as move distance. +
    • +
  • +Pasted shapes and instances now are selected initially. +
    • +
  • +Enhanced OASIS compression mode (can be chosen from the options dialog on
    +saving). Reduces file size considerably by creating regular shape arrays if +possible at the cost of higher memory consumption and longer writing times. +

Features:

+ +
    +
  • +A couple of RBA extensions: API's for shape properties, rulers and geometry
    +selections. +
    • +
  • +A bugfix for the OASIS reader (sometimes crashing the reader on
    +CBLOCK-compressed input) +
    • +
  • +A function to descend into a cell in the hierarchy but keeping the context,
    +which is shown in dimmed colors. This function can be found in the "Display" +menu and is called "Descend". To use this function, select a shape or instance +inside the cell into which to descend. "Descend" then enters the next cell +along the path that leads to the selected shape or instance. +
    • +
  • +The mouse wheel can be used to zoom in and out. +
    • +
  • +Shift+right mouse button pressed now allows to "drag" layout in a "Google maps" fashion. +
    • +
  • +Copy & paste now is available for layers as well. +
    • +
  • +A ruby console is provided where ruby commands can be executed interactively. +
    • +
  • +The way how the selection is displayed can be configured now (color, line width
    +and vertex size). +
    • +
  • +The interrupt signal now is enabled again even if Ruby is activated (Ctrl+C
    +now works again). +

Features:

+ +
    +
  • +Support for arbitrary angles on cell instances. +
    • +
  • +A bugfix for the OASIS reader (CTRAPEZOIDS have not been read in some
    +cases). The OASIS reader now uses shape arrays to achieve are smaller +memory footprint in some cases. +
    • +
  • +Multiple transformations are now allowed on layer source expressions
    +(see Transforming views and property selectors for a detailed description). +
    • +
  • +Rulers now are configurable to a large extent. Multiple ruler templates may
    +be defined from which a certain ruler type can be chosen. Some of the new +ruler styles are no longer "rulers" but rather "annotations". See Ruler +properties for a description of that feature. +
    • +
  • +Last, but not least: KLayout now can be scripted to some extend using Ruby
    +as the scripting language. For more information about this feature, see +RBA introduction. +

Version 0.11

 + +

Release date: 2007-06-26

+

Download links

+ +

Features:

+ +
    +
  • +Some bugs were fixed in the OASIS implementation. CBLOCK compression now
    +is supported. Forward cell name references (numerical ID is used before +being associated with a string) are supported as now. File global properties +are now read correctly. A bug reading certain CTRAPEZOID objects was fixed. +(Still, forward references are not allowed for text/property strings or +property names). +
    • +
  • +A layout properties dialog has been added that shows basic properties of
    +the layout such as top cells, layers and others. +
    • +
  • +The "Select Cell" dialog has been enhanced with the capability to hide
    +and show multiple cells in the cell list. +
    • +
  • +A "zoom fit" mouse gesture was implemented: moving the mouse up and right
    +with the right mouse button pressed now fits the current cell into the window. +Moving up and left still zooms out. +
    • +
  • +A bug in the GDS2 reader, dropping polygon points in rare cases, was fixed +
    • +
+ +

Version 0.10

 + +

Release date: 2007-05

+

Download links

+ +

Features:

+ +
    +
  • +The build script has been enhanced and supports Qt installations with
    +different locations for binaries, libraries and headers. See the Build +section for details about this. +
    • +
  • +OASIS files can be read as well now. The reader automatically determines
    +the kind of file. OASIS layer names are supported. Due to the complexity +of the OASIS specification, or more precisely the effort required to test +a reader for meeting the specification, OASIS support currently is regarded +to be in "beta" state. +
    • +
  • +Layers can now be organized hierarchically. Layers can be grouped which
    +allows to control visibility and other properties for the group as a whole. +Layers can be removed from the layer view list or new layer views can be created. +
    • +
  • +The layout can be transformed (rotated, shifted, mirrored) now. This
    +transformation is specified in the layer panel as a part of the layer +source specification. An optional transformation can be applied per layer +or layer group. This way for example, different layouts can be aligned +over each other. +
    • +
  • +Shape properties now are supported. Each shape may carry optional
    +properties that are read from GDS or OASIS files. A property selector +can be applied per layer view, so that a layer only shows these shapes +that match the given property selection. +
    • +
  • +As an experimental feature, the inverse layout tree can be visualised
    +by allowing the minimum hierarchy level to go into the negative range. +The effect of this is, that a cell is shown in the context of all of +it's direct parents, if the first hierarchy level is set to -1. If set +to -2, the cell is shown in the context of all of it's parents and +grandparents and so on. Since there is no particular optimization for +this feature, performance may be poor, if a cell must be painted in a +huge number of contexts. In addition, the context displayed does not +participate in selection or ruler snapping. +
