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.
