WebDec 8, 2024 · It will help solve any hold violations. 3. Increase the clock-q delay of launch flip-flop. Similar to the previous fix, by choosing a flop that has more clock-q delay, delay can be induced in data path logic. It will ease timing and help solve hold time violations. 4. Use a slower cell for launch flip-flop. WebFigure 27-1: Determining Setup Time with Bisection Violation Analysis The Star-Hspice Bisection feature greatly reduces the amount of work and computational time required to find an accurate solution to this type of problem.
