A method for simulation and testing of complex integrated circuit modules and cards including a mix of analogue and digital devices using Computer Aided Design (CAD) tools produced for testing and simulating digitally orientated switching circuits only, involves conceptually reducing the analogue content of the circuit to a combination of logic gates representing the analogue functions. Provided the combination produced can respond to digital input patterns in the same way as the actual circuits would respond to the same inputs from a CAD tester, then the circuit can be said to be represented. The benefit of this method of simulation and testing is that the models can be used on any module or card irrespective of the nature of the surrounding circuits.
