In one case, I found the components of the timing path (same star point, same end point) is difference between Astro's timing-report and DC timing-report. Anyone can tell me why?
Thanks
Because these two tools use different algorithms to calculat path delay, and the most important thing is path delay reported from dc is load based and path delay in astro is RC based.
because the wire load model is different between astro and DC.
