Unified simulator: an alternative to traditional simulation techniques

Categories of traditional simulation techniques and their differences have been explained in this paper. Disadvantages of presenting complex circuit components using structural modeling techniques where each simple circuit component is represented by rows and columns in the system matrix have been pointed out. A unified simulation technique is outlined. This paper proposes a new approach to circuit simulation, where components are treated equally regardless of their type. The benefits gained through this approach is outlined in details. More specifically, this technique allows simulation of analog circuits from a system-level point of view to a more sophisticated design where the complete topology of the circuit is known. A unified simulation algorithm has been developed for small size analog and digital circuits. Our experimental results show that not only unified simulation is feasible, it has a better speed compared to traditional simulation techniques
