If I use touchstone output model, the prbs response is fairly close.
What is it close to ?
Is there any reference ?

What do you compare with ?

Again describe correctly.I guess followings.
- You have some reference as correct results.
- Results of transient analysis using s4p(4 ports s-parameters) from Q3D are cosistent with reference results.
- But results of transient analysis using W-element from Q3D are not consistent with reference results.
My guesses are correct ?
If so, Q3D itself is correct.
Your settings for dumping W-element model file from Q3D are wrong.
Upload your netlist of HSPICE, s4p file and model-file for W-element.
