This paper introduces a fully automated verification technique that permits to analyze real-time systems described using a continuous notion of time and a mixture of operational (i.e., automata-based) and descriptive (i.e., logic-based) formalisms. The technique relies on the reduction, under reasonable assumptions, of the continuous-time verification problem to its discrete-time counterpart. This reconciles in a viable and effective way the dense/discrete and operational/ descriptive dichotomies that are often encountered in practice when it comes to specifying and analyzing complex critical systems. The paper investigates the applicability of the technique through a significant example centered on a communication protocol.
