Algorithms for automatic test-pattern generation
Tom Kirkland, M. Ray Mercer · IEEE Design & Test of Computers · 1988
Three well-known algorithms for the automatic test pattern generation (ATPG) for digital circuits are the D algorithm, Podem, and Fan. The author introduces the concept of test generation and analyzes the way each algorithm uses search and backtracking techniques to sensitize a fault and propagate it to an observable point. The heuristics used to guide ATPG search and the notation used to represent circuit values are examined.>
