今天又查了点资料,synopsis 的timing guide里有关于latency 的详细说明,先摘抄如下:
Latency is the amount of time it takes for the clock signal to be propagated from the original clock source to the sequential elements in the design, consisting of two components, source latency and network latency. Source latency, also known as insertion delay, is the time it takes for a clock to be propagated from its ideal waveform origin point to the clock definition point in the design.
Network latency is the time it takes for a clock to be propagated from the clock definition point in the design to a register clock pin.如下图所示: |
