detailRoute vs trialRoute

Rajesh Vembu

Is there a way to report the differences/ratio of detail route vs trialroute net wirelengths?

Currently reportWire command reports the ratio of detailRoute vs half-perimeter net wirelengths. However, if trialRoute statistics were also included in this, it would be great.

 Are the net lengths stored as part of the net object in encounter?

  • Hi,

    I have a question related to this topic and would appreciated if someone could help: I have a design which trialRoute and globalRoute cong map show good congestion and timing. globalDetailRoute however detour a group of signals (about 100) around one memory (where trialRoute just route straight through) which causes 400ps timing difference for this group. "optDesign -postRoute" couldn't bring the timing back to pre-route (~ -100ps WNS). The design still routable. Any comments, suggestions?

    Thanks.
