WebNov 4, 2024 · Path-based Analysis (PBA) is a pivotal step in Static Timing Analysis (STA) for reducing slack pessimism and improving quality of results. Optimization flows often invoke PBA repeatedly with different critical path constraints to verify correct timing behavior under certain logic cone. However, PBA is extremely time consuming and state … WebOct 1, 2012 · However, analysis requires more memory and CPU resources compared to those required for the critical-path based method. Assuming two reg-2-reg timing paths with the same data path delay, the path with the lesser common clock path might get missed using critical-path based approach. Consider the following example:
