WebMay 10, 2024 · Common Path Pessimism Removal (CPPR) A timing path consists of launch and capture paths. The launch path has further components – the launch clock path and the data path. In the above circuit snippet, the launch path is c1->c2->c3 -> CP-to-Q of FF1 -> c5 -> FF2/D. The capture path is c1->c2->c4->FF2/CP. Late and early derates are set … WebClock Skew and Short Path Analysis As mentioned earlier, clock skew and short-path problems emerge when the data propagation path delay between two sequentially adjacent flip-flops is less than the clock skew between the two. Figure 6 is a general diagram of the delay blocks in a sample circuit. Figure 5 • Setting Shortest Paths and Best Case ...

Tool doesn't know whether a buffer is clock buffer or normal … WebI see very different things in the destination clock path area of the two paths. In the first, non-exception case, the destination clock path delays include destination FD setup time, clock uncertainty, clock pessimism and the route the clock took up to the FD. In the second case with a set_max_delay exception, only the FD setup time is included. dwf nhs resolution
