The authors propose a method of formal verification of fault-tolerance of sequential machines using regular temporal logic. In this method, fault-tolerant properties are described in the form of input-output sequences in regular temporal logic formulas and they are formally verified by checking if they hold for all possible input-output sequences of the machine. The authors illustrate the method of its application for formal verification of fail-safeness with an example of a comparator for redundant system. The result of verification shows effectiveness of the proposed method
