| Abstract: | This paper presents a modified nodal decomposition approach for faulty subnetwork location in large analog circuits. The suitable self testing conditions and mutual testing conditions are developed for all kinds of decomposition cases in which subnetworks satisfied solvability conditions. The procedure for locating faulty subnetworks and the example are given. The approach provides an even more efficient method for locating faulty subnetworks in large analog circuits. |
