Re: how to setup tstab in pss and pdisto |

Joon,
If you're using pdisto, then you are using an old version of the
software.
I would definitely recommend using IC5033 or IC5141 (where it is
called qpss) as the algorithm to do the initial convergence was
radically improved. tstab behaved a little strangely before that was
introduced (tstab in PSS is OK, but in pdisto it was problematic).
I think that most of the algorithm was backported to pdisto/qpss in
IC446 - something like 4.4.6.500.69 rings a bell.
Are you using any kind of recent version? That's definitely where I'd
start first.
Andrew.

In the analysis, I found that tstab is playing very important role. It
can speed up the simulation and gives very good convergences.
Can anyone know how to set tstab up? Does it depend on operating
frequencies, LO and RF, or depend on the Mixer output frequency?
thanks. |
