Setup time 和 hold time
Web11 Nov 2014 · 94. Nov 11, 2014. #18. Setup time is the time duration of the Data signal that is BEFORE the clock signal leading edge. Hold time is the time duration of the data signal that is AFTER the clock signals leading edge. If the Data signal leading edge and Clock signals leading edge are aligned and locked in-sync , you will have no setup time or ... WebThe setup time is specified for -1.5ns, and the hold time is 2.6ns. Figure 2 illustrates the minimum setup time for the MAX5891. Note that, in reality, the data transition occurs …

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 …
