[reposted from #analog-design] Hello all, I created a new project to use the repository from my MPW4 analog project, which could pass the precheck in MPW4 but didn't submit for some missing buffer blocks. The design is DRC-clean in magic using the full rules. Unfortunately, this time it fails due to "Klayout FEOL" error at the Efabless platform for MPW5. During the office hour a while ago, @User suggested to check the Klayout .xml file generated in the OG platform (at [proj_name]/jobs/mpw_precheck/[job_name]/outputs/reports/klayout_feol_check.xml in this case). The errors I see are related to nsd.1 and psd.1 in a couple of small blocks (see the screenshot below). Coming from Magic (in which I double-checked no errors are flagged for drc(full)), I don't know how to interpret this. Any ideas, anyone? @User is this a known issue? any idea how to solve it? I'm really close to the tapeout (I believe), I'd really appreciate your help!

@User Last year it was discovered that there were rules related to nsmd/psdm missing from the rule decks. magic generates nsdm/psdm on cifout and there may be some corner cases where that creates problems between non-standard cells. Are your gds and xml files available?
