I was wondering if anyone there has run into this one?
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.
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,
