    The parameter definitions of the parent circuit will be updated:

    Parameters of the child circuit as well as parameters in their expressions
    will be treated as follows:

    #. If the parameter is a parameter of the parent circuit, then the child 
       needs to obtain the value given with the parent circuit.
    #. Else if the parameter is a parameter of the prototype circuit, then the
       child needs to obtain the value given with the prototype circuit
    #. Else if the parameter is defined in a user library (in _USERPARAMS),
       then the definition from this library needs to be added to the parameter
       definitions of the parent circuit.
    #. Else if the parameter is defined in a system library (in SLiCAPPARAMS),
       then the definition from this library needs to be added to the parameter
       definitions of the parent circuit.
    #. Else: the parameter name will receive the postfix: _<parentRefDes)>.
