This paper presents an integrated methodology to detect and locate electrical continuity and leakage between and within two groups of nets. Skilling (1982) addressed the leakage problem and patented a clever method with complexity of O(n). By using group testing methods, Chen and Hwang (1989) improved complexity to O(log2N), and Chen and Chen (2011) introduced the statistical method to further reduce the number of tests required to detect and locate leakage. In this paper we extend Chen and Chen's (2011) method to address both leakage and continuity problems. Based on Bayesian techniques, we present an integrated testing methodology to incorporate circuit topological information and a defective database into the testing algorithm to reduce the number of required tests. Furthermore, the integrated methodology presented can be implemented by most commercial test equipment.
