WebJun 3, 2024 · 1 Answer. If you know the single cycle datapath, and want to take that to multi cycle, generally speaking we subdivide the single cycle into stages. As only one stage will execute at a time, a relatively simple state machine controls what stage to execute currently/next to activate the appropriate stage, and deactivate the others.

"WebMar 8, 2011 · 1 - Specifying timing constraints for multi-cycle paths is totally annoying. 2 - The fanout for the clock enables is such that it does not hit the limit for MAX_FANOUT yet. As such no register duplication occurs. But the clock enable has to reach flip flops that are spread out far enough that some of the more distant ones do not meet timing. " - Ise multicycle

In your case, the lack of clock-enable on capture_com_rx_packet_counter would make it "unsafe". It should be possible to force the synthesis tool to use a flip-flop primitive with a clock-en, which would be the first step to …

WebJun 30, 2015 · The only performance advantage of the non-pipelined multicycle machine is that execution times for instructions don't have to be equal (in a singlecycle machine execution time of all instructions equal the execution time of the worst case instruction) but some instuctions can be executed in shorter time than others. On the average, however, … WebI have a path that is set as multicycle path for the setup check. For some reason, PrimeTime seems to be treating it as a multicycle path for hold time checking as well.
