This paper deals with systems verification techniques, using Bounded Model Checking (BMC). We present a new approach that combines BMC with symmetry reduction techniques. Our goal is to reduce the number of transition sequences, which can be handled by a SAT solver, used in the resolution of verification problems. In this paper, we generate a reduced model by exploiting the symmetry of the original model,which contains only transition sequences that represent the equivalence classes of the symmetric transition sequences. We consider the construction of a new Boolean formula that manipulates only representative transition sequences. In our technique, we present a method that combines the symmetry reduction technique with BMC for the reduction of the space and time of Model Checking.
