Re: critical path delay

1. Read in your design in to design compiler
2. report_timing
It will give you the critical path delay.

Re: critical path delay

report_constraint -all_viol -max_delay will give all violating paths in each path group. Path groups are depends on the number of clocks in your design(default) else u can also specify path groups ..

report_qor will also tells, in each path groups ,whats the path delay ..
