Nettet29. nov. 2016 · Yes. How to solve Intra-clock-path timing violations ( setup and hold ) Provided that you follow good FPGA design practices (mainly using dedicated clock routes) - hold time violations will rarely occur. Setup violations are common and can be mitigated by pipelining (adding registers between combinatoric logic blocks), avoiding … 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.

Nettet1.1.5.1. Multicycle Clock Hold. The number of clock periods between the clock launch edge and the latch edge defines the setup relationship. By default, the Timing Analyzer performs a single-cycle path analysis. When analyzing a path, the Timing Analyzer performs two hold checks. The first hold check determines that the data that launches … Nettet8. des. 2024 · It will help solve any hold violations. 3. Increase the clock-q delay of launch flip-flop. Similar to the previous fix, by choosing a flop that has more clock-q delay, delay can be induced in data path logic. It will ease timing and help solve hold time violations. 4. Use a slower cell for launch flip-flop. randy nadeau https://rixtravel.com

NettetIn 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.
