How does clock tree latency affect timing

WebAug 4, 2015 · Clock latency is the time taken by the clock to reach the sink pin from the clock source. It is divided into two parts – Clock Source Latency and Clock Network Latency. Clock Source Latency defines the delay between the clock waveform origin point to the definition point. WebAug 6, 2012 · Because of this, clock latency to that register group can increase since a clock gating cell typically has a higher delay than a clock buffer. This can be rectified either by …
