Abstract :
The problem of exhaustive test generation for detection of coupling faults between cells in word-oriented memories is considered. According to this fault model, contents of any w-bit memory word in a memory with n words, or ability to change this content, is influenced by the contents of any other s-l words in the memory. A near optimal iterative method for construction of test patterns is proposed. The systematic structure of the proposed test results in simple BIST implementations
