Timo, 

If you have limited tools in  your SI tool chest (and a lot of time) you
could put together a bunch of .measure statements to re-run your simulation
in a batch mode, and then post process your results.

I think in Hspice, the Temperature is not a variable, once specified, it can
not be varied during a transient simulation.
 
However, if you have simulator support Verilog-AMS, you can specified
temperature as a variable and even simulate self-heating/thermal run-away
effect. I have done it in the past.
 
But I am not sure whether current Hspice version support this.
 
best,
 
Yafei

Subject: [SI-LIST] Hspice temperature as a variable


Hi all,

     I would like to ask some of the Hspice experts
in this form a question.  I would like to vary the
temperature during the transient simulation.  Does
anyone know how to do so?

     For instance, I would like to vary the
temperature
linearly or other wise as the time goes from 0nS to
200nS.  How do I do so?  Your help on this matter is
greatly appriciated.

Best regards,

Timo
