Hi @akrinke, I just pushed to the repo some device DRC QA cells (f.e. for sealring):
https://github.com/IHP-GmbH/IHP-Open-PDK/blob/dev/ihp-sg13g2/libs.qa/drc/devices/sg13g2_qacells.gds
Could you please run the updated deck on it, and check whether the results are expected (please note, that it could be that the QA cells are not up-to-date)

Hello @sergeiandreyev, I've added the device DRC QA cells to our regression tests. For the sealring, we have some unexpected filler width (e.g. M1Fil.a1) and Seal.d violations we have to investigate.
