WebA properly designed multicycle path has the ability to stall its pipeline when it isn't ready to accept data. Thus, for the first set of inputs to outputs, the latency would be 10 ns, but for the second set of inputs to outputs depending on … WebSimply adding a multicycle path may not be correct - you have to make sure the timing of these paths work at both min and max delays, and that the data will come back on the same clock regardless of which process corner you are at. Right now, your picture shows clk1 and clk2 ans being phase aligned - they won't be. syr to srq https://sticki-stickers.com
