I believe that Allegro PCB SI HSpice compatibility feature can fit your needs. You should ask your Cadence support AE for this.

To do that I need to create a netlist for HSpice and I need W element (RLGC) of the trace. I cannot create that by hand. Can anyone tell me whether I can create the W element or Netlist of a specific differential trace under interest from the board file in Cadence? Is there an option in the tool. I have a 3d modeling tool. But the touchstone gives only S matrix I believe. How can I get the W element of the trace so that I can use it in HSpice?
