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. WebMulticycle Path Analysis. 1.1.5. Multicycle Path Analysis. Multicycle paths are data paths that require an exception to the default setup or hold relationship, for proper analysis. For example, a register that requires data capture on every second or third rising clock edge (multicycle exception), rather than requiring capture on every clock ...

WebJun 4, 2015 · 1 Answer. Sorted by: 3. When using multicycles, you must be careful that the path is indeed multicycle-safe. 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 … WebLoading Application... // Documentation Portal .
