Synthesizing fault tolerant safety critical systems

To keep pace with today's nano-technology, safety critical embedded systems are becoming less tolerant to errors. Research into techniques to cope with errors in these systems has mostly focused on transformational approach, replication of hardware devices, parallel program design, component based design and/or information redundancy. It would be better to tackle the issue early in the design process that a safety critical system never fails to satisfy its strict dependability requirements. A novel method is outlined in this paper that proposes an efficient approach to synthesize safety critical systems. The proposed method outperforms dominant existing work by introducing the technique of run time detection and completion of proper execution of the system in presence of faults.
