Hi @Tim Edwards, I managed to skip the m1.7 BEOL violations with the latest PDK and I have a clean local precheck. Unfortunately, the efabless website precheck gives me an FEOL exception, like the ones reported here on this slack channel on Sat 6th. The project's GDS can be found here: https://github.com/cloudxcc/WaveSync_007.git Since there is no additional information available, this would mean a full stop for the months of hard work for me. Do you have any advice for what I can do ? Thank you in advance, cheers Tobias

I'm not sure what's going on. I suggest posting an issue on the github tracker for https://github.com/efabless/mpw_precheck . I don't know if something changed with the klayout DRC deck, or klayout, or the DRC script, or if it's something else entirely. But the fact that you got the error and it was also reported earlier this month suggests that something broke.

Today my both Pre-check and Tapeout check passed at efabless website, Not sure above issue specific to analog projects
