Automatic production of the pseudo-circuit Boolean for the failure bounds analogue diagnosis scheme

A basic for partial automation of the failure bounds analogue diagnosis method is given by Wu and Wu. An extension to their work which enables the complete pseudo-circuit to be simulated using any commercial simulator (in this case SPICE) is described. The pseudo-circuit is formed in such a way as to require only a simple comparison to produce the intermediate Boolean diagnosis state vector, prior to use within the failure bounds decision algorithm.
