This dissertation studies the verification of reachability properties of concurrent systems where the components of the system are Labeled Transition Systems (LTSs) using a symbolic model checking technique called Bounded Model Checking (BMC). BMC is a technique that seeks to answer the question whether among the system’s executions shorter than some given number of steps there is one (or more) violating a given property. Answering this question is reduced to propositional satisfiability, i.e., to a propositional formula that is satisfiable iff there is such a violating execution. The translation from a system to a formula is polynomial in the size of the system but the running time of the propositional solver can be exponential in the number of atomic propositions in the formula. This number, on the other hand, correlates directly with the number of execution steps that the formula models. Traditionally, LTSs are model checked by composing the component
