Does anyone know why I meet some DRC problems after passing the whole OpenRoad flow? I have tried many versions, but they all don't work. Attach my GDS file, magic DRC report, and klayout DRC check txt.

@Jianwei Jia file a github issue here https://github.com/The-OpenROAD-Project/OpenROAD/issues along with test case. Share your repo link as well

OK, thank you!

Looks like it's a problem with the standard cell

sky130_fd_sc_hd__buf_16

. You can file a issue like @Vijayan Krishnan suggested, but I'd file the issue at https://github.com/google/skywater-pdk/issues since it's related to the pdk. Tagging @Tim Edwards just for fun. Is this a corner case error for contact conversion from gds to magic?

OK, thank you, Mitch! Amazing.

@Jianwei Jia, @Mitch Bailey: This and about five other cells have DRC errors in the original skywater-pdk. I have corrected versions of them in open_pdks, and the corrected versions are installed as part of the open_pdks sky130A/sky130B installation. If you don't use the open_pdks install, then you will be missing literally hundreds of corrections to the original PDK.

@Tim Edwards Thanks for the info. I'll try to remember that in the future.

Thank you, Tim!
