Webflow (clock tree synthesis, or CTS). While this divergence has so far received little media attention, this paper shows that timing divergence is severe—so much so that we believe it is having a critical impact on the economic viability of migrating to the 32nm process node. Clock concurrent optimization is a WebApr 14, 2013 · Clock latency is the delay between the clock source and the clock pin. It is dependant on hardware, PCB, traces, etc. Simply, Clock latency means, the number of clock pulses required by the ckt to give out the first output. Clock latency is the combination of source latency and network latency.
