Property Driven Three-Valued Model Checking on Hybrid Automata

Abstract. In this paper, we present a three-valued property driven model checking algorithm for the logic CTL on hybrid automata. The technique of multivalued model checking for hybrid automata aims at combining the advantages of classical methods based either on the preorder of simulation or on bounded reachability. However, as originally defined, it relies on the preliminary definition of special abstractions for combined over- and under-approximated reachability analysis, whose size is crucial and can be infinite. Our procedure avoids the oblem, since it is based on an incremental construction of the abstraction for the original hybrid automaton, that is suitably driven by the property under consideration.
