Progressive Bridge Identification

We present an efficient algorithm for identification of two-line bridges in combinational CMOS logic that narrows down the two-line bridge candidates based on tester responses for voltage tests. Due to the implicit enumeration of bridge sites, no layout extraction or precomputed stuck-at fault dictionaries are required. The bridge identification is easily refined using additional test pattern results when necessary. We present results for benchmark circuits and four common fault models (wiredAND, wired-OR, dominant, and composite), evaluate the diagnosis against other possible fault types, and summarize the quality of our results.
