issue_reproducible.tar.gz This is a reproducible at detailed routing stage for OpenROAD. The width of the part of Metal3 pins at the right side that's inside the boundary is less than the min width of Metal3. This shouldn't happen and I believe is the source of the error. I think OpenROAD should catch this and avoid bad routing (for example at location 3166.64, 795.11).
