Generalized parameter extraction method for analog circuit fault diagnosis

The symbolic technique for analog fault diagnosis is presented in this paper. The cancellation-free Generalized Parameter Extraction Method for parametric fault diagnosis of electronic circuits is considered. The topological conditions of diagnosability of the active analog circuit are discussed. The algorithm for automotive fault diagnosis is proposed and implemented with the Cirsym symbolic analyzer. The experimental results on a filter circuit show the efficiency and reliability of proposed technique.
