In constraint manager I set the value for impedance and make all nets close to certain tolerances. Then I it auto route and have bunch of impedance mismatch DRCs
1)I thought its constraint driven tool, so it should have routed within the tolerance of impedance I specified.
2)How to fix impedance mismatch. I try delay tuning, it didn't work. It just adds more delay.
1. As far as I know, it just checks whether the impedance constraints are met or not.
2. They depend on the geomerty and the materials but not on the length.
