How is s-parameter simulation done in Cadence virtuoso?

hmcheema

I want to know how s-parameters are calculated in Cadence virtuoso sp simulation? Is their a document explaining the same?

 I am simulating three versions of a TSMC kit inductor with different lengths of interconnect connected to it. I extract their layouts using Calibre and then do a s-parameter simulation on the extracted views. However, i get the same inductance and Q-factor as well as impedance on smith-chart for all three cases.

 On the other hand the same structures if simulated in EM based HFSS give different inductance for all different cases.

Please guide asap. Thanks a lot.

  • It's unlikely that the issue is anything to do with the sp analysis, but more likely to be due to how you've extracted it. There's a short description in "spectre -h sp" and also in the <MMSIMinstDir>/doc/spectreref/spectreref.pdf but I doubt that's anything to do with the problem.

    Are you extracting inductance in Calibre or just resistance and capacitance?

    This is probably a better question for Mentor Graphics, since Calibre is their tool.

    Best Regards,

    Andrew.
