checkRoute or VerifyConnectivity

Vij Krish

Hello Everyone,

I was finishing the layout via Innovus and ran verifyConnectivity followed by checkRoute.

verifyConnectivity was okay and it showed no errors and no warnings, whereas checkRoute showed there are 3 unrouted nets.

When i ran the checkRoute command again immediately, it showed no unrouted/unconnected nets.

Which of these commands should we trust or is this really unrouted nets issue?

Looking forward for a response, thanks in advance.

Regards,

Vijay

  • If you can find the net name use selectNet 'name' and see if you have a route segment or via that is missing, may be a weird blockage on a cell pin....sometimes the founry put odd blockages on the std cell or macro pins...hope this helps
