Running a script to auto update Model of instances after Spice netlist import

TravisMN

I imported a Spice netlist to create schematics, but it is not automatically assigning the Model to the instances in the schematic and instead assigning them "none". In the GUI, I must right click on each instance of over 1000 cells in my library and select "Revert "Model" to default (pmos_1p2v_lowvt_tg)" to update them before I can get a clean LVS run on each cell. Is there a SKILL method to do this on all of the instances of all of the cells in my library?

    I'm not really sure why it would be importing the model as "none". That's strange - I wonder if something is wrong with your device mapping setup.

    Potentially you could just do this to clean up the instances:

    foreach(inst geGetEditCellView()~>instances
      dbDeletePropByName(inst "model")
    )

    I'm guessing the actual model property is called "model" (lowercase) - you should check in the CDF for the device to find the name rather than the prompt

    This code above removes the instance-level override and should then revert to the CDF default.
