Line to Line violations inside diff pairs?

pdxg8r

Hi everyone, I was hoping someone could help me out with my situation. I'm using Allegro 16.3S018 and I'm running into a problem I've never seen before. Here's my set up:

  •  Differential Pairs assigned in Constraint Manager
  •  In CM, I have physical properties assigned throug a net class, including a diff pair gap of 4.15mil.
  • I also have a spacing properties of 20 mil line to line.
I'm getting line-to-line violations within my diff pairs, pointing to my 20 mil l-2-l rule. Isn't the Diff pair spacing supposed to override the line to line spacings within diff pairs? Am I missing something?

Thanks in advance!

    that did the trick. I had it set 0, but when  i set it to my primary gap, they went away. I guess I'm not exactly sure what that property does.

    Thanks!
