Hi @Tim Edwards @Mitch Bailey @mehdi @Amro Tork we are working for past week to remove drc error but we weren’t able to resolve them. We need help from community to help us resolve these issue. @Juan Sebastian Moya and I discussed in detail and tried to solve them but we couldn’t. So at least two teams are facing these DRC of IO.3a2 and IO.1a2 do anybody know how to resolve them. Because according to our understanding circuit is fine if anybody is willing to add any comment that would be helpful. Following is the repo link https://github.com/sardaratif71/PICO_2023_TOP.git @aquiles viza i see you have added some script to see drc in the klayout. As I don’t see these errors in klayout if you can share that script or how to integrate that with klayout.

Hi atif, I have a semi automated way to filter the drc errors that come from the padring and not the design from those files. I have a folder for each drc run given by Juan Moya, then • Update the Makefile with the name of the gds and

Run

that you want to see • run

make klayout-raw-results

and store the drc information on a lyrdb file (File... > Save as > filename.lyrdb) • Then run

make klayout
