|
|
In the "File" menu, choose |
|
|
</p><ul><li>"Open" to close the current view and open a new layout instead |
|
|
of the currently loaded one</li><li>"Open in Same Panel" to open a new layout in addition to the |
|
|
currently loaded one</li><li>"Open in New Panel" to open a new layout in a new view</li></ul><p> |
|
|
Either way, a file selection dialog will appear where a file can be |
|
|
chosen for loading. After choosing the file and clicking "Ok", the |
|
|
file is loaded. |
|
|
</p><p> |
|
|
The program will automatically determine the type of the file. Currently, |
|
|
OASIS, GDS2, DXF, CIF, LEF/DEF and a text version of GDS2 are supported. |
|
|
Gerber PCB data can be read with some preparations too (see <a href="import_gerber.html">Import Gerber PCB Files</a>). |
|
|
If the file is gzip/zlib compressed, it will be uncompressed automatically. |
|
|
</p><p> |
|
|
Certain options can be specified for the file loader using the |
|
|
reader option pages. To open the reader options dialog, choose |
|
|
"Reader Options" from the "File" menu. This dialog allows specification of |
|
|
certain options for all "Open" actions, for example: |
|
|
</p><ul><li>Confine the reader to a certain set of layers. All other layers are not read.</li><li>Disable reading of text objects. Text objects don't carry geometrical information |
|
|
for masks and can be discarded this way.</li><li>Disable reading of user properties. If properties are not required, the memory consumption can be reduced by disabling |
|
|
properties.</li><li>Certain GDS specific options which mainly control the level of compatibility with other tools.</li><li>Other formats may offer other options too. Specifically rich formats such as DXF or LEF/DEF can |
|
|
be configured in manifold ways. Different tabs show options for different formats or format groups.</li></ul><p> |
|
|
Using "File/Reload", the currently loaded file can be re-read from disk. |
|
|
Usually this is not required, because KLayout will automatically check whether |
|
|
the file has changed and offer to load it. |
|
|
</p><p> |
|
|
By picking a file from the "Open Recent" list in the "File" menu, a previous |
|
|
file can be loaded again. |
|
|
</p><p> |
|
|
Files can be given to KLayout on the command line and are loaded |
|
|
automatically. Multiple files can be specified. They are shown in different |
|
|
pages by default. To load multiple files into the same page, add a "-s" option |
|
|
to the command line. "http:" or "https:" can be specified on the command line |
|
|
as well. In this case, KLayout will download the files from the given URL. |
|
|
</p><p> |
|
|
Files and URL's can be dragged and dropped on the KLayout main window. |
|
|
KLayout will then load and show these files. |
|
|
</p><p> |
|
|
Layout files can be associated with technologies. Technologies allow |
|
|
associating a layout with additional data, such as libraries, macros, |
|
|
net tracer settings, layer properties etc. |
