Subject: What's The Technique To Handle Hierarchical Capacitance Problems?
John,
I was just wondering if you could answer a quick question for me. I'm having
problems with violating capacitance constraints on nets in my hierarchical
design. Performing
report_constraint -max_capacitance -all_violators
gives a number of violators, some of which I have resolved by doing set_load
on those ports ... others just won't budge whatever I do. I've tried
characterizing and re-reporting, characterizing and re-synthing but nothing
works. Can you tell me what the recommended procedure is to resolve these
types of violations ????
