Cellular automata-based signature analysis for built-in self-test

Relevant signature analysis properties for elementary one-dimensional cellular automata are presented. It is found that cellular automata with cyclic-group rules provide signature analysis properties comparable to the LFSR (linear feedback shift register). A technique of using CALBO (cellular automata-based logic block observation) for both test pattern generation and signature analysis, in a similar manner to a typical BILBO (built-in block observation) implementation, is presented.<
