Timing violation是什么意思
WebJan 2, 2024 · Thanks for the tips. We compiled the original design without any changes. It only had minimal timing violations, specifically on "Recovery" only, unlike when we compiled it to Gen-3 x8 which yielded more timing violations as was found on the sta.rpt file I attached previously. We also have tried the steps you mentioned. WebDec 11, 2012 · Timing Violation Messages. When a system timing check encounters a timing violation, the simulator reports the following information: Time of the second event (the violation) Time of the first event Value of the timing check limit File and line number Instance name of the module in which the violation occurred Time of the violation

WebHowever, excessive negative skew may create a hold-time violation, thereby creating a lower bound on TSkew ( i, f) as described by equation 4.6 and illustrated by l in Figure 4.2. A hold-time violation is a clock hazard or a race condition, also known as double clocking ( Friedman, 1995; Fishburn, 1990 ).
WebSetup Time Check. A Setup Time Violation exist if a data transistion happens and the following is true: Source Clock Delay + Tpd > Clock Period - Destination Register Setup Time + Destination Register Clock Delay. The slack is defined to be margin we have from the violation, is is computed by simply replacing the comparison with a subtraction: Web但是从数字后端工程师的角度来说，遇到了setup violation应该怎么修掉呢？ 首先，我们回忆一下setup的定义。下图-1展示了一条典型的timing path以及setup的计算方法。 图-1.
