All, I know this problem we've run into it before but the solution escapes me. We have electrical drc's associated with the diff pair nets NBUF_DO_IN_P and NBUF_DO_IN_N? It appears allegro thinks r641 and r675 should be a short distance so it is not recognizing the diff pair routing between the 2. There is nothing in the schematic to support this. Any Ideas?
