For … Web18 Apr 2014 · I first tried using a "set_multicycle_path" AND and "set_false_path -hold" with the "set_max_skew". The false_path here, again, caused the set_max_skew to ignore the paths completely. Next I tried removing the "set_false_path -hold" but keeping the "set_multicycle_path". Now the design misses timing on the max_skew specification.
