WebDec 3, 2013 · Move gates around to make the total distance between different cells in the violating path smaller (less capacitance to drive = faster transitions) Insert retiming flops on the path, if the design will allow for it (try to do an operation in two clock cycles instead of one) Reduce the overall clock frequency. For hold time violations: WebDelay ( max) Required time = clock adjust + clock delay FF2 (min) - set up time FF2. Clock adjust = clock period (since setup is analyzed at next edge) Calculation of Hold Violation Check: C onsider above circuit of 2 FF connected to each other.
