WebFixing Hold Time Violations. Revisit Example 3.11 and assume that the system has 50 ps of clock skew. Solution. The critical path is unaffected, so the maximum clock frequency remains 3.33 GHz. The short path increases to 80 ps. This is still less than t hold + t skew = 110 ps, so the circuit still violates its hold time constraint. WebJun 24, 2024 · 255. oratie said: It is possible to have both setup/hold violations on the same reg2reg path: if you have big "delta delay", which is due to big coupling capacitance on some nets in the path.
