Hi,
I want to report the worst paths in a design. Worst means the ones that the synthesizer/backend-tool has a harder time to close timing for.
I DO NOT just want the ones with the smallest slack, because low slack doesn't mean this path makes timing-closure harder. E.g. a relaxed path might use low-drive strength cells and no LVTs and thus have similar slack with a much harder path.
Is there a way to identify the paths that give the tools a hard time during timing-closure (or synthesis)?
Thanks,
George
