WebAug 24, 2011 · The constraints file has a set_clock_latency -source command. If it is removed, then 20 builds will pass. We can't do a gate level simulation as the design includes both a PCIE and a DDR2 controller. Why does the set_clock_latency constraint impacts the design implementation 20% of the time, not more or not less? WebThe latency consists of the following components as shown in Image 3: Latency: It is the amount of time a clock signal takes to propagate from the original clock source to the sequential elements in the design. Source latency: It is the delay from the clock source to the clock definition pin in the design.
