A self-checking PLA automatic generator tool based on unordered codes encoding

Self-checking circuits ensure concurrent error detection by means of hardware redundancy. An important drawback of self-checking circuits is the fact that they involve a significant increasing of the design time. Specific CAD tools are needed in order to cope with this drawback. In this paper the authors present a tool allowing automatic generation of self-checking PLAs. Then they validate this tool by transforming a set of PLA benchmarks into self-checking PLAs and give statistics concerning the required area overhead.<
