Behavioural modelling of mixed signal ASICs: A new multi-level approach

This paper describes a new behavioural simulator based upon an optimised Piece-Wise Linear (PWL) representation of signals that can model mixed signal systems at various levels of abstraction. The authors show how analogue and digital models that are both efficient and accurate can be constructed from a small set of universal building blocks. Example applications are given and compared with results from a commercial SPICE type simulator. The new simulator is shown to offer a large reduction in execution time with only a small loss of accuracy
