TSMC 65nm GDS Import Problem

M Refaat
Hi there,

I am using TSMC 65nm GP Standard Cell library in my design. After I finish P&R using encounter and export GDSII file, I am trying to import it to Virtuoso in order to have DRC/LVS using Calibre. The problem is that not all layers are imported, almost all layers used for power rings/routing are not there. I think the problem is the mapping file.

So, I appreciate if any one has a solution for that or have a mapping file that is compatible with this technology.

Best,
Parents
  • Are you saying the problem is with the mapping file in Encounter? Or the stream map file in Virtuoso? The stream map for virtuoso should have come from the foundry and is usually considered golden. You can create the encounter stream map from that. The format is in the documentation.
