Hi,

Does anyone knows how can I simulate the temperature that has some
frequency (and not as a parameters)?

For example, I want to simulate what happens to a circuit when the
temperature is going up and down in a periodic manner - what is the
influence of that?

Thanks,

You can vary temperature over time, since MMSIM62. Look in
<MMSIMinstDir>/doc/spectreuser/spectreuser.pdf for a section headed "Sweeping
Parameters During Transient Analysis" (search for param_vec in the pdf and
you'll find it). You have to specify it in a piece-wise way (rather than a
periodic way) but it's fairly straightforward.

How do I run this command? Do I need to write an ocean script for
that?

If you're using a recent enough IC build (either IC5141 or IC613/4) you'll see a
checkbox "Dynamic Parameter" on the Transient Analysis form in ADE.

If not, then go to the Options button on the tran analysis form, and at the
bottom where it says "Additional Parameters" (in IC613/4 this is on the Misc
tab), type in the additional parameters, e.g

param=temp param_vec=[0 25 10n 30]

etc.

If you look at the resulting netlist, the tran analysis should have these
additional parameters, as described in the documentation.

Andrew.
