| Abstract: | A novel procedure is presented to test and diagnosis faults in large scale analogue circuits.Large change sensitivity analysis is used to obtain diagnostic voltages and currents.Decomposition technique is applied and algorithms for isolation of faulty nodes,faulty connections and faulty subcircuits are proposed.The hardware overhead problem is considered and it leads to an optimization of test nodes.The circuits analysis based on symbolic technique is less complex than traditional method.One circuit is performed and the results show the efficiency of this method. |
