I did try this in Cadence Spectre. It is always difficult when you don't have any DC value in your S-par. So what I did was I added DC value manually into the touchstone file. You can use any quasi-static extractor for this e.g. Q3D, PakSI-E, TPA, Extract IM, and etc. I also chose the spine interpolation property for the S-par. It went well. regards, Saoer On 11/27/07, Sanjeev Gupta <skgupta2005@xxxxxxxxx> wrote: > > Hello All > I am trying to do time domain simulation using Agilent ADS after > extracting > s-parameter model from Power SI. > But, i am getting lot of convergence issue.
