Testing iterative logic arrays for sequential faults with a constant number of patterns

Shows that a constant number of test vectors are sufficient for fully testing a k-dimensional ILA for sequential faults if the cell function is bijective. The authors then present an efficient algorithm to obtain such a test sequence. By extending the concept of C-testability and M-testability to sequential faults, the constant-length test sequence can be obtained. A pipelined array multiplier is shown to be C-testable with only 53 test vectors for exhaustively testing the sequential faults
