Plotting transistor parameters in a temperature sweep

CADcasualty

I'm doing a temperature sweep using:

analysis('dc ?saveOppoint t ?param "temp" ?start "-40" ?stop "120" ?step "20" )

Aside from the usual voltages and currents, is it possible to also plot an operating point aspect of a device e.g. mn1's threshold vth or transconductance gm?

    Yes, add:

    saveOpPoint( "/I7/M1" ?operatingPoints "gm vth" )

    This corresponds to the Outputs->To be saved->Select OP Parameters entry in ADE L. Having done that, you can then plot OS("/I7/M1" "gm") or using getData("I7.M1:gm" ?result 'dc)  - unfortunately for the latter you have to use the netlist name for the component.

    Regards,

    Andrew.
