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. WebThere are two forms of clock latency: source and network. Source latency is the propagation delay from the origin of the clock to the clock definition point (for example, a clock port), and network latency is the propagation delay from a clock definition point to a …
