I would like to plot gm, gds, cgs, cgd, etc. as a function of time in my spectre transient sims using analog artist. How do I do this?
I'm did not understand completely, what you want. The save statement "save M1:oppoint ..." seams to save the final operating point parameters. If you want to access theses values you can do this using the following way:
\o (tranOp subckts instance "tranViolations-violations" model "tran-info" variables output designParamVals tran primitives)
\o --> a huge list with all possible outputs :)
Now you can access the final operating point parameters (gm, gds, cgs ....) using the squiggle operator:
Here you just have one value for the final operating point. You can carry out a parametric analysis to get an parameter plot e.b. cgs vs. Vds.
Is this what you want?
