Hold time fixing
NettetSetup time, hold time, and propagation delay all affect your FPGA design timing. The FPGA tools will check to make sure that your design meets timing, which means that … Nettet9. apr. 2013 · Route:466 - Unusually high hold time violation detected among 226 connections. The top 20 such instances are printed below. The router will continue and try to fix it. Then it crunches for 10-15minutes until it gives me timing report informing me that All setup time constraints was met and that there are 3 hold time violations for …

Conventionally, buffer … NettetGreetings Readers! In the previous blog, setup and hold time concepts were discussed in detail (click here to read). Now, this blog is mainly based on analyzing the setup and hold timing reports generated by the STA tool. For timing analysis, paths can be categorized into four categories mentioned below.

You will get the true status of the hold violations only after the CTS stage. So we give importance to hold fixing post CTS and set violations are considered in the earlier stages itself.

Nettet7. des. 2016 · Clock skew will effect both setup and hold. On a hold path, clock skew directly influences your hold time margins because you must hold to the slowest possible receiver clock wrt launching clock. On a setup path, clock skew directly influences your setup margins because you must setup to the fastest possible receiver clock wrt to … Nettet1. aug. 2024 · Compared to a previously proposed approach using fixed hold time margins, Monte Carlo simulations show that, averaging across 10 ISCAS’85 benchmark circuits, our proposed method can reduce the number of inserted hold buffers by 8.4% with a 6.2% improvement in timing yield and by 21.9% with a 1.7% improvement in …
Nettet15. nov. 2024 · The hold time was violating in the second path by 1ps which also got resolved because the buffer addition delayed the data launch in the second path by 2ps. Since we had a good margin for hold slack in the first stage, it will not violate the hold timing there. In this way, useful skew helps meeting timing. Harmful Skew:
