To see the Noise of certain Instances in the Noise Summary during PSS/PNOISE analysis

RFStuff

Dear All,

I want to see only the noise contribution of certain instances in NOISE SUMMARY PRINT list.

The Result->Noise summary Setting snapshot is attached in the post.

But if you see it showing a complete blank list in the result summary.

Could anybody please tell what is the issue and how to fix it ?

Kind Regards,

Parents

  • Some things to check - if you look in the results browser, open up the pnoise results, and you'll see things like the output noise and so on. You should also expect to see the noise contributions from each noise source in each instance. If they're not there, it's not saved...

    If not saved, then one thing to check is if you have set "nestlvl" in the Outputs->Save All form (or Save Options - can't remember what it's called). If you've limited the number of levels of hierarchy with nestlvl, it won't save the noise contributions.

    Maybe you could post the bottom part of your input.scs (from the end of the testbench to the end - i.e. all the options and analysis statements)?

    Regards,

    Andrew.
