WebJun 26, 2015 · After CTS is finished, the clock is said to be in “propagated mode”. What is clock latency? Clock latency is an ideal mode term. It refers to the delay that is specified to exist between the source of the clock signal and the flip-flop clock pin. This is a delay specified by the user – not a real, measured thing. WebMay 4, 2012 · Try to choose D pin of flip-flop whose clock is driven by the clock you want to see whether propagated or not. For ex: report_timing -view func_worst -to dut/sr_q_reg/D. The report_timing will take less time to run. After that, as mentioned above by pradeep, just look at clock network delay value to see if it is ideal or propagated. May 2, 2012.

WebPropagation time. In digital circuits, propagation time is the delay of the basic inverter of a given family. Thus, it measures the speed at which such family can operate. [1] 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 simplifies the propagated clocks model by assuming that the launch and capture clock paths have the same delay (i.e., that L=C.) In this case the setup and hold ... navy\\u0027s football helmets https://asouma.com
