Web8 Ways To Fix Setup violation: Adding inverter decreases the transition time 2 times then the existing buffer gate. As such cell delay of 1 buffer gate ≈ cell delay of 2 Inverter gate. So stage delay (cell delay + wire delay) in case of single buffer < stage delay in case of 2 inverter in the same path. [Synthesis/STA] fixing setup and hold ... WebApr 9, 2013 · When I synthesize the project the timequest timing analyser claims that the setup time on a given capture flop is failing by ~0.317ns but the hold violation is passing 0.378ns. My question is; if the tools know that a given path is failing setup time but not hold and there is enough slack in the hold time to fix the violation in the setup time.
