Whereas, the propagation delay would simply be the delay between the two edges, like an input output example below. PFA. So in other words, does this mean propagation delay between clock signals is kind of a clock skew, which is measure of …

Web1 day ago · Here the model used to describe the evolution in time of the clock originally proposed in [41] is assumed. The clock model derives the clock time and frequency errors for each epoch from the previous one. The two main clock noises considered are: White Frequency Modulation (WFM) and Random Walk Frequency Modulation (RWFM). WebThe propagated clocks model of timing is the definitive criteria for correct chip function, and is the one used by timing signoff tools in design flows. An ideal clocks model of timing …

WebThe clock is propagated through the entire clock tree network in the netlist in order to determine the clock latency. In other words, the delay across each cell in the clock tree and the interconnect wiring delay between the cells is taken into account. The following command instructs PT to propagate the clock through the clock network:
