Webset_clock_group -asynchronous. Both constraints prevent the Compiler from optimizing slack between asynchronous domain crossings. set_clock_group is the most aggressive … WebFor example, if the source clock is twice as fast (half period) as the destination clock, a -start multicycle of 2 is usually required. Hold multicycles (-hold) are computed relative to setup multicycles (-setup). The value of the hold multicycle represents the number clock edges away from the default hold multicycle. WebTo see if it is possible to capture the window, look at the setup and hold slack measured above (before the set_multicycle_path command). If the sum of the two slacks is positive, then it is theoretically possible to capture the window if you can generate the correct clock phase from the MMCM. cricut design space make it button greyed out
