| Hello, | |
| I am trying to do floorplanning with OpenROAD with ISPD benchmark superblue16, but I am struggling with so many problems. | |
| I am quite new to this filed, so my knowledge for this filed is not high enough. | |
| I uploaded .lef, .def. and .v field given by ISPD and tried to do floorplan, but this error line "LEF MASTER ~CELL HAS NO LIBERTY CELL" appeared and does not work at all. | |
| I am glad if anyone has any idea about this error and how to work with this kind of open bench mark. | |
| Thanks | |

| I don't see any uploaded files. Based on the message you have a cell called "~CELL" that exists in LEF but for which you have no .lib. | |

| Thanks to all of you | |
| I followed the order of commands that @QuantamHD recommended and it worked although LEF file seems to have some syntax errors. | |
| Global placement (GPL) worked well, so I am very happy with this result. As @rovinski mentioned, global placement also worked without importing .lib file. Regarding with global placement, I have none of problem. I appreciate to all of you. | |
| I am also trying to run floorplanning with openroad as I want to follow the paper (https://vlsicad.ucsd.edu/Publications/Conferences/389/c389.pdf), embedded in the floorplan machine for openroad. | |
| Although the ISPD contest porblem is provided as "floorplan" finished, I want to re-floorplan with openroad and | |
| compare the results between openroad and as it is given. | |
| I tried the commands as shown below, | |
| ``` | |
| read_verilog superblue16.v | |
| read_lef tech.lef | |
| read_lef superblue16.lef | |
| read_lib superblue16_Early.lib | |
| link_design superblue16 | |
| write_def superblue16.def | |
| read_def superblue16.def -floorplan_initialize | |
| partition_design -max_num_inst 1000 -min_num_inst 200 -max_num_macro 1 -min_num_macro 0 -net_threshold 0 -virtual_weight 500 -report_directory . -report_file report | |
| ``` | |
| Am I on the right track? | |
