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 :)

    I finally found the answer by assembling pieces here and there.
    1- Create a file name.scs everywere you want
    2- Write Inside : simulator lang=spectre
    save M0:gm
    save M0:cds
    save M1:Ron
    etc....
    Where M0, M1 are devices names and gm cds Ron are their proper parameters.
    3- import this file in ADE L > setup > Simulation Files > definition files
    4- In ADE L > Outputs > Setup : Add new expression correspunding to the parameter of the device taht you want to plot.
    ex: Name: gm
    Expression: pv("M1" "gm" ?result "tranOp")
    then add.
    5- Open result Browser, plot tran. :)

    And there you got your transistor's parameters evolving through transient simulation.
