Web15 Sep 2024 · In the previous blog on STA (Setup and Hold Time - Part 2), details given in the timing report were discussed. To understand the timing report is very important because, in case of timing violations, the first task is to analyze the timing reports. By analyzing the timing report one can reach the root cause of the timing violation. There can be multiple … Web9 Apr 2008 · Setup and Hold time. The setup time is the interval before the clock where the data must be held stable. The hold time is the interval after the clock where the data must be held stable. Hold time can be negative, which means the data can change slightly before the clock edge and still be properly captured. Most of the current day flip-flops ...
