Display operating point

santoshvema
Hi, I am using CMOS 90nm technology in cadence and I just wonder how I can display the region of operation, gm, and id etc for my transistors. I tried the same steps that we used to do for cmosp18 technology in cadence but I couldn't succeed. Thanks. -Santosh

     I assume you mean by using Results->Annotate in ADE? Assuming Spectre is your simulator

    If the devices are defined as subcircuits then you need to also check the CDF->simInfo->spectre section for the device.

    Look at the opParamExprList for dc operating points and optParamExprList for transient op points.

    The parameters would need to be defined here if the models were subcircuits and they wanted the results to be defined based on component values from within the subcircuit.
