  • Method for synthesizing soft error tolerant combinational circuits
    Patent number: 8640063
    Abstract: The method for synthesizing soft error tolerant combinational circuits includes the step of inputting a combinational circuit to a combinational circuit analyzer for analysis. The analyzer then extracts smaller sub-circuits from said combinational circuit, computes probabilities of input vectors to occur for each of the smaller sub-circuits, produces new multi-level sub-circuits from the extracted sub-circuit, and maximizes logical fault masking against the occurrence of a single fault applied to the new multi-level sub-circuits, the maximizing being based on probabilities of sub-circuit input vectors to occur. Finally, the analyzer merges the new multi-level sub-circuits back to the original inputted combinational circuit.
