From at least e0f692f46654d6c7c99fc70a0c94a080dab53571, sky130B/libs.tech/klayout/drc/klayout_gds_drc_check.py contains

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

Maybe this needs to be forwarded to the rule maintainer repo.

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:

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?

@d-m-bailey : That would come from https://github.com/efabless/sky130_klayout_pdk.
