Abstract

This paper describes a method of detecting and locating faults automatically in analogue and mixed-signal circuits; the circuit representation used allows the tolerance of all component parameters to be considered simultaneously. Fault detection is accomplished by checking whether the measurements are consistent with a model of the circuit. Automatic fault diagnosis is accomplished by tracing the source of the inconsistency.
