Hi all,
I am currently routing a PCB that has multiple differential pairs. Each has to have 0.15mm pair gap, which I have implemented in a custom rule (will change depending on layer in final version).
The issue I am having is that once I correct for the differential pair skew, when I run DRC it now shows hundreds of gap issues due to the added length matching skew.
Is there a way to turn this off the gap check rule for segments that have length tuning added to them?
I’m wondering if this might be a bug, as its only the top section of each skew curve that is being highlighted as an error as shown bellow:
I was using 9.0.0, updated to 9.0.1 and same issue.
Tried on 8.0.5 and it didn’t show any errors, though it also didn’t show any errors when I purposely separated the differential pairs.
Edit: Tried 8.0.9 and this has the same issue.
Its a bug, looks like it was introduced in 8.0.9.
