An efficient algorithm for test generation is presented. In the authors' algorithm, the test generation problem is formulated as the model of a global search of the sensitizing paths between the primary input and output nodes. Such a simple model offers significant efficiency improvements for test generation of large combinational circuits. The algorithms is tested using the ISCAS'85 benchmark combinational circuits. The experimental results on large circuits indicate that the algorithm outperforms deterministic test generation algorithms. The overall test system efficiently generates test vectors for large size combinational circuits with a high degree of test coverage.>
