clock skew too great (37) - CSDN文库
WebIn the timing report there are 4 sections: summary, source clock group, data path, destination clock group. In summary section there is a summary of the other 3 groups. For data path the summary says ~1ns cell delay and ~3 ns (75%) routing. Source clock & destination clocks are the same and there is not much skew so your clocking looks OK. WebIt unfortunately delays the cutoff time for holding a data signal. Negative Clock Skew. If the destination clock is less delayed than the source clock, it represents negative clock skew with respect to that path. This gives less time for a path to settle and advances the cutoff time for when a signal must hold. Setup Timing Slack in Critical Path rcw practice test
