Dear All, I'm trying to simulate with Hspice some models generated by HFSS, from an S(f) param analysis. I find that every time I choose in HFSS the option << Combine Sweeps >> the Hspice simulation does not converge. I suppose that it could be because results from different sweeps on different frequency range (sweep1:0-10GHz sweep2:10GHz-20GHz) do not match exactly (at 10GHz. Did someone find a similar problem? does someone know a way to obtain better results?
