Fixing setup and hold violations

Web10 Ways to fix SETUP and HOLD violation: Static Timing Analysis (STA) Basic (Part-8) WebMar 23, 2024 · This blog is intended to help users who are facing Hold violations (WHS: Worst Hold Slack) which are higher than 0.3 ns after place_design completes. There are some tool options available that help to reduce the hold violations before even starting the route_design. route_design always gives priority to fixing hold violations over setup.

WebHold time is similar to setup time, but it deals with events after a clock edge occurs. Hold time is the minimum amount of time required for the input to a Flip-Flop to be stable after a clock edge. In the figure, the green area represents the t su or Setup Time. The blue area represents the t h or Hold Time. WebAbout. *Good understanding and knowledge on all aspects of VLSI Design Flow.
