After adding Prop delay property on nets in schematic (Concept), package to Allegro, all nets are assigned to a Matched Length group in CM. Set target, add delta / tolerance and assign pin pairs as Longest Pin Pair. _Everything is fine until packaging schematic changes to Allegro next time!_
After packaging, the delta / tolerance is defaulted back to *0 mil:5%??? Thus causing all Prop delays to fail. * Any Ideas? Anyone using this? I just finished a design using this method, but it never did this. P.S. I really like the idea of assigning in the schematic. Thanks in advance, Mark
