    If the element model is not a built-in model, and the model definition
    is not included in the circuit, the definition will be taken from a
    library file.

    If the element model is not given the default device model will be used.

    If the element is not a subcircuit, the model attribute will be set to that
    basic model (e.g. 'Q2N3904' will be replaced with 'Q'), and model
    parameters that have not been defined will obtain their default value.

    If the element is a subcircuit model parameters that have not been defined
    with the call will obtain their default value.
