Re: Hi,I have a problem about how to use a model include sub
Only spectre have the feature that a npn for instance could be either a primitive device with a model or a subcircuit model. So that the device netlist is unchanged and you only change the model be either a primitive or a subcircuit. If you use other simulators then all device should be subcircuits defined in the model file or part where you can change the type of description.
Cadence have a patent on this,
