Digital. I see the step was run but nothings in the log. I wonder if it's because I used the klayout gds instead of the magic? I bypassed the final folder.
Do you see a message like "KLAYOUT_FILLER_SCRIPT is unset. KLayout.Filler may not be supported for the gf180mcuD PDK. This step will be skipped." in the LibreLane flow log?
Then I don't know the answer either without looking at the project.
Since the project template generates the GDS with the sealring, you could move your changes over to a fresh repository.
Great! Normally, the final GDS should be inside the folder librelane/runs/<timestamp>/final/gds/. If there is no file in this folder, it means that an error occurred during the process. Did you get any errors at the end of the flow?
