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

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,

    I think the limit is 32767 & total components number is 58564.  Could you please clarify whether I am right in this REGARD ?

    Yes. You're right. I think that should be better in IC61X.

    On the other issue, it may be that the particular component (the resistor r1 or recn in the noise summary) does not have an isnoisy parameter, and so is not being turned off. The noiseoff_inst simply sets isnoisy=no for all components under the hierarchy given; if that's not a valid parameter for that component, the noise won't be turned off. You may need to look in the models to see what component the r1 and recn instances are; this may also be simulator version dependent (I'm not sure which version you're using).

    It might be simplest to talk to customer support so that we can look at your data with you.

    Regards,

    Andrew
