Analog fault diagnosis: a fault clustering approach [PDF]
Proceedings ETC 93 Third European Test Conference, 2002 A novel analog circuit fault diagnosis method is proposed. This method uses a neural network paradigm to cluster different faults. It is capable of dealing with the common fault models in analog circuits, namely the catastrophic and parametric faults. The proposed technique is independent of the linearity or nonlinearity of the circuit.
