Hey all,
I was just wondering if I can find out the critical path of a big combinational circuit using Synopsys Primetime or any other CAD tools?

Thanks

In general I would expect DRC and Monte Carlo methods will determine critical timing and path length issues. Critical path (shortest latency) results should come out of a manual or auto generated set of test vectors in combinational and sequential table and generate the results which could be sorted. But I offer no step by step solution on each.

In CAD tools, there are commands for reporting the critical nets. In Cadence EDI tool, i think the command is reportCritNet.
