| Abstract | Results are presented for a variation on a builtin self-test (BET) technique based upon a distributed pseudorandom number generator derived from a one-dimensional cellular automata (CA) array. These cellular automata logic block observation (CALBO) circuits provide an alternative to conventional design for testability circuitry such as built-in logic block observation (BILBO) as a direct consequence of reduced cross-correlation between the bit streams which are used as inputs o the logic unit under test. The issue of generating probabilistically weighted test patterns for use in built-in self-test is also addressed. The methodology presented considers the suitability of incorporating structures based on cellular automata, a strategy which, in general, improves test pattern quality. Thus, CA-based structures qualify as attractive candidates for use in weighted test pattern generator design. The analysis involved in determining and statistically |
