In SPB 16.3 hotfix 20 (maybe implemented in 18) Allegro Constraint manager will no longer report a same net via to via spacing drc if those vias are covered (direct connect) by a shape. Cadence says that once the via is covered with a shape the pad ceases to exist and it simply becomes a hole to hole issue. Technically I can see the point. However it forces me to think in a different manner (not necessarily bad)
Does anyone see any potential problem with the tool failing to report a DRC for same net V\V spacing when those vias are direct connected to a shape?
