A Game-theoretic Approach for Synthesizing Fault-Tolerant Embedded Systems

In this paper, we present an approach for fault-tolerant synthesis by combining predefined patterns for fault-tolerance with algorithmic game solving. A non-fault-tolerant system, together with the relevant fault hypothesis and fault-tolerant mechanism templates in a pool are translated into a distributed game, and we perform an incomplete search of strategies to cope with undecidability. The result of the game is translated back to executable code concretizing fault-tolerant mechanisms using constraint solving. The overall approach is implemented to a prototype tool chain and is illustrated using examples.
