WebOct 20, 2016 · Try implementing a 64-bit * 64-bit (C = A*B) non-pipelined multiplier with a 400 MHz clock on the input and output registers and I'm pretty certain that won't make timing and would require a multicycle path from the A and B inputs to the C output register. guru2kiot Points: 2 Helpful Answer Positive Rating Sep 8, 2016 K kommu4946 Points: 2

As expected, on applying a hold multicycle path of 1, the hold will return back to 0 cycle check. Figure 7 below shows the effect of below two commands on setup and hold checks. As is shown, setup check gets relaxed by one launch clock cycle.
