Testability of one dimensional ILAs under multiple faults
M.M.R. Gala, Karan L. Watson, Don E. Ross · 2002
Testing of one dimensional unilateral iterative logic arrays (ILAs) of combinational cells under multiple faults is discussed. It has been shown that it is possible to generate a test set for ILAs with primary outputs under multiple faults. Some ILAs have a constant number of test vectors independent of the size of the array. These types of arrays are called C-testable arrays. Present work proves that all useful one dimensional unilateral ILAs with only boundary outputs are not C-testable under multiple faults.>
