A new scheme for board level fault diagnosis based on Cellular Automata Array (CAA) has been presented. In the proposed scheme the output responses of the chips are encoded by applying the encoding strategy of CA based byte error correcting code. The encoded symbols for different test vectors are compressed to a signature. Employing the same decoding structure of byte error correcting code chips are detected as faulty or not. The CAA based design for the fault diagnosis results in a simple and modular structure hence well suited for VLSI implementation
