It is well-known that in principle automatic test pattern generation (ATPG) can be solved by transforming the circuit and the fault considered into a Boolean satisfiability (SAT) instance and then calling a so-called SAT solver to compute a test. More recently, the potential of SAT-based ATPG has been significantly extended. In this paper, we first provide introductory knowledge on SAT-based ATPG...
This paper proposes a method to compute delay values in 3-valued fault simulation for test cubes which are test patterns with Xs. Because the detectable delay size of each fault by a test cube is fixed after assigning logic values to the Xs in the test cube, the proposed method computes a range of the delay values of the test patterns covered by the test cube. By using the proposed method, we can...
