In this work we develop a new technique for over-approximating (in the sense of timed trace inclusion) continuous dynamical systems by timed auThis technique refines commonly-used ...
Abstract. We establish mutual translations between the classes of 1safe timed-arc Petri nets (and its extension with testing arcs) and networks of timed automata (and its subclass ...
Abstract. In this paper, we propose a new approach for formal verification of hybrid systems. To do so, we present a new refinement proof technique, a weak refinement using step in...
Abstract. We present a new open source model checker, opaal, for automatic verification of models using lattice automata. Lattice automata allow the users to incorporate abstracti...
Abstract. The integrated logic-based modeling language, Timed Communicating Object Z (TCOZ), is well suited for presenting complete and coherent requirement models for complex real...
