I am writing to ask about running Monte Carlo analysis on swept/saved oppoints. I have a small MOS resistor circuit with two pass transistors, and I sweep their control voltage, and plot their combined "ron" (saved oppoints), as well as the region of both transistors. In ADE-L, the oppoints work fine and I need to see mismatch behavior (which I do via ADE-XL)
In ADE-XL I defined the corner setup, apparently correctly with model files, swept DC parameter (voltage), etc., but once run is completed, it fails to plot and complains of evalation error "eval err", for all three expressions. I think this is likely due to the expression itself which is picked up from result browser originally, e.g. ronPlot is:
plot((getData("I0.MpIn:ron" ?result "dc-dc") + getData("I0.MpOut:ron" ?result "dc-dc")))
Now is there a way one can succesfully plot a family of ron vs. vCtrl expression, including mismatch?
Cadence sub-version is IC188.8.131.520.14
Attachements: The desired curve Ron vs. Vctrl curve via saved oppoints in ADE-L, and corner setup (failed results)
