Summary :

Recently, Burch et al. proposed symbolic model checking method to verify sequential machines formally. The method, which is based on logic function manipulation using binary decision diagram, can handle large sequential machines that cannot be handled by the conventional techniques. The expressive power of Computational Tree Logic (CTL), which was used by Burch et al., is not very powerful, for example, CTL cannot describe repetition of events. This papers shows an extension of the symbolic model checking algorithm to Branching time regular temporal logic (BRTL), which has been proposed by the authors as an improvement of CTL in terms of expressive power. The implemented verifier based on the proposed algorithm could verify behaviors of a microprocessor composed of approximately 1,600 gates and 68 flipflops.
