PSS and HB vs. Transient having touchstone models from HFSS

Hello every one

I have designed a 100GHz oscillator and in order to see how much power it can produce I run different analyses. The issue is that the output voltage is quite different when I use different analyses. The frequencies are similar but the amplitudes are totally different. I have used PSS with harmonic balance and also probe-based HB (these two simulation give very similar results). However when I use Transient, the amplitude of the node voltages is quite different (the frequency is very similar).

Which one can I trust?

Thank you very much,

Hamid

PS: I have couple of transmission lines whose model are coming from EM simulation in HFSS.

    Hi Hamid, Please see this blog... It talks about the improvements to nport starting in MMSIM 12.1. http://community.cadence.com/cadence_blogs_8/b/rf/archive/2012/11/19/spectre-rf-mmsim-12-1-preview-of-coming-attractions
