How to plot transistor's parameters evolution over time with transient simulation

Edouard R

Hello,


I am sorry if I wrote at the wrong place. (first time)

As a beginner on Cadence (student), I would like to know how to plot transistors parameters (Betaeff, Gm, Cgs, Cdg ...) over a transient simulation.

In fact, I would like to see the parameters values changing over time through a plot. To begin, I have only one transistor.


I've seen other topics, but they last from many years ago (4, 5 or even 8) and I don't understand what people did to plot parameters.

Can someone help me ?

Thanks :)

    Not sure which IC version you're using but in an IC616 hotfix (6.1.6.500.10 - ISR10) or later, you now have Outputs->To be saved->Select OP Parameters which means you don't have to create an include file with the save statements. You can even get the op parameters to be plotted automatically from this form too. In IC616 ISR12 we also added the OS and OT buttons in the calculator to access the operating point parameters during a DC sweep or transient so that you don't need to use the results browser.

    Regards,

    Andrew.
