pp. 181-192An Approach To Analogue Behavioural Modelling

A mathematical approach to the terminal behaviour description of analogue subsystems is presented. The formulation which can be widely used is a possible base of the model imple-mentation by the help of behavioural languages. It enables the user to develop behavioural models independently of special languages and supports him in offering a modelling method. The mathematical formulation gives also important criteria to evaluate new language con-cepts. Examples are given using the HDL-A language. Since the midseventies the program SPICE and SPICE-like versions have been used for net-work simulation. In these cases the simulation task is formulated by the help of netlists describing a connection of basic SPICE elements like resistors, capacitors, inductors, control-led sources etc. Often subsystems have an unknown structure in early design phases, or net
