NettetFrom the possible hold relationships, the Timing Analyzer selects the hold relationship that is the most restrictive. The hold relationship with the smallest difference between the latch and launch edges (that is, latch– launch and not the absolute value of latch – launch) is selected because this determines the minimum allowable delay for the register-to … Nettet其中：. 对于图-1中的timing path，hold check需要满足如下条件：. 同上篇中的setup相同，在实际设计中，因为会有一些margin加入，所以计算公式与上述略有不同，但本质没 … NettetAlso design has very critical hold and setup path from memory and to memory.

Nettet1. okt. 2012 · Any extra pessimism in timing analysis not only requires more time to fix the critical paths but could negatively impact other important parameters such as power and area. In the worst case, it might leave no option but to reduce the functional frequency of the design. On the other hand, optimism in timing analysis might result in silicon failure. Nettet18. jun. 2024 · A setup or hold time violation for registers in the destination domain, typically flip-flops, can cause the flip-flop to enter a condition known as metastability. … people who retired in 2022NettetIn other words, we can also say hold timing analysis is performed in the same clock period where setup timing is performed. Let’s say that a multi cycle path setup of N was applied, if no explicit hold multi cycle path is set, the default hold check will be performed at (N-1) th edge of destination clock. people who resist

Nettet7. jan. 2024 · Static Timing Analysis (STA): It is performed without use of any set of vectors with the goal to report the timing paths having the timing violations that are setup and hold violations. It is vector less approach.

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.
