DRC Checks on GDS Failed, Reason: Total # of DRC violations is 390
in a region which doesn't make sense to me. The violating areas start out in my PNP array, but veer way off from any relevant part of the design. When I check my layout with drc(full)
(I select all area and do DRC Update
) I don't get any violations. I read some of `open_pdks/sky130A/libs.tech/magic/sky130A-GDS.tech`and saw that it mentions Generally, this covers rules not found in sky130A.tech
. In any case, I don't understand why I would need any deep nwell for parasitic PNPs.Tim Edwards
