Hi everyone, We had a DRC clean online Precheck and we ran the Tapeout with it. The BEOL and FEOL errors were 65969 and 1143100 respectively. That seems like a lot of errors that didn't get caught in any earlier stages? @jeffdi @Mitch Bailey @Tim Edwards @Boris Murmann

Can you post an error type summary?

There should be an xml file with a summary of the drc error types.

There is one on the Open Galaxy. I don't know how to download that file from the Centos machine...
