Definition and design of strongly language disjoint checkers
I. Jansch, Bernard Courtois · IEEE Transactions on Computers · 1988
Strongly language-disjoint (SLD) checkers are to sequential systems what strongly code-disjoint checkers are to combinatorial systems. SLD checkers are the largest class of checkers with which a functional system can achieve the totally self-checking goal. Self-checking sequential systems are first addressed, and formal definitions of SLD checkers are given. The design of SLD checkers based on regular combinatorial self-checking components is then considered.>
