Abstract :
This paper describes a testable design for random pattern testing. Factorization is one of the basic techniques in the testable design. Factorization of AND and OR based expressions has been studied for years, and EXOR operations have been used in the logical design. We propose factorizations based on EXOR operations widely used recently. The experimental results show that the average of the decreasing rate of the tests is 18% and our methods are effective in enhancing the random pattern testability
