An enhanced one-step C-testable design of two-dimensional iterative logic arrays

The authors present an improved approach to one-step C-testability of orthogonal two-dimensional iterative logic arrays. This is an improvement of the approach of W. Huang and F. Lombardi (1988) and H. Elhuni et al. (1986). A group of sufficient conditions to test two-dimensional iterative logic arrays with a constant number of test vectors independent of the array size (C-testability) is stated. It is proved that the proposed approach requires a smaller number of test vectors than in previous works.<
