This paper presents an efficient method to diagnose single and double bridging faults. This method is based on Delta Iddq probabilistic signatures, as well as on the Viterbi algorithm, mainly used in telecommunications systems for error correction.The proposed method is a significant improvement over an existing one, based on maximum likelihood estimation. The (adapted) Viterbi algorithm takes into account useful information non considered previously. Simulation and experimental results are presented to validate the approach.
