Hi there, A "while" ago I used to be able to assign a net spacing type to diff pairs which would keep the pairs apart, while allowing the primary gap to be maintained. I have assigned a net spacing type to all signals in my diff pair bus, and find that I get line-line violations within the pairs, it is looking for 40mil sep, which is the value I wanted for the pair to pair sep. Has the way Allegro handles this changed, or has it been too long since I did this last? I set up diff pairs in CM, on 15.2 s036. I recall this came up a few months ago....
