Propositional satisfiability problem (SAT) is a fundamental problem both in theory and practice. In the area of software engineering, people employ various techniques, such as model checking, theorem proving, automated testing and so on, to ensure the quality of software. Those techniques are usually based on SAT solvers. The efficiency is an important criterion for a good SAT solver. Besides, the...
Model checking suffers from the state explosion problem. Compositional abstraction and abstraction refinement have been investigated in many areas to address this problem. This paper considers the compositional model checking for timed systems. We present an automated approach which combines compositional abstraction and counter-example guided abstraction refinement (CEGAR). The proposed approach...
