[SOLVED] LVS error in Cadence IC616

[Mudasir Mir]

While doing LVS for my circuit I am getting following errors....Can anyone tell me what are these???
1. ptap must be connected because of same Net/diffNet
2. 'nsd' must be connected because of sameNet/diffNet

Thanks!!!

The error messages tell you: The 'ptap' (substrate) and 'nsd' (probably n-well) connections are missing.

I don't see a substrate connection here. Provide a substrate connection and the issue will be solved.
