Conformal LEC: performance during Hier_compare

AsicMax

I am running LEC using hier_compare. The design after uniquify has 24 copies of the "same" module in golden and revised. The first couple compare in 15seconds each then each one starts taking 15minutes or more. It seems to get stuck at "84% Comparing 101 out of 120 points, 0 Non-equivalent". I have not tried hacking the hier compare script to put these modules more at the top. (They do not depend on any other modules, only library cells.) The only thing I can see that is "different" from the transcript, is that the slow down occurs after an unrelated module had a non-equivalent point.

Any ideas on why these modules are taking so long (at least some of them)?

    Hi

     

    Are  you running with the latest, 10.10-s480? Can you insert 'usage -auto'? I'm thinking it could be the memory usage starts exceeding the available memory and the run starts swapping.
