Abstract :
It is shown that one-dimensional, unilateral iterative logic arrays (ILAs) of combinational cells are C-testable for multiple sequential faults, provided the fault-free cell functions satisfy appropriate conditions. The test sequence is of length O((m 2n2+mn3)× K), where n (resp. m) is the number of signal values that can be applied to the horizontal (resp. vertical) cell input and K⩽n-1. Linear testability is also considered. The ripple-carry adder circuit (n=2, m=4) is shown to be C-testable with 699 test vectors
