Hi All, I'm trying to make klayout drc from command line but I'm not sure which drc files use. For now I'm relying on precheck drc but I think the the others should be important as well. Also, the drc file

klayout_gds_drc_check.py

holds a reference to the gf180mcu precheck drc in line 68:

Copy code

klayout_sky130A_mr_drc_script_path = Path(__file__).parent.parent.parent / "tech-files/gf180mcuD_mr.drc"

Maybe I should change that to sky130A_mr.drc? That's the same to run the precheck drc directly?

lvs_run.py

also has an error because it relies on

sky130.lvs

being on

$PDK_ROOT/$PDK

, not in libs.tech/lvs. For now the solution is use

sky130.lvs

@aquiles viza What precheck repo are you using?

The files with problems are not from the precheck repo, are from volare (open_pdks commit bdc9412b3e468c102d01b7cf6337be06ec6e9c9a). The sky130 precheck file I'm using is https://raw.githubusercontent.com/efabless/mpw_precheck/main/checks/tech-files/sky130A_mr.drc

DRC and LVS is fine when using

sky130A_mr.drc

and

$(KLAYOUT_HOME)/lvs/sky130.lvs
