Abstract. We investigate layered composition for real-time systems modelled as (networks of) timed automata (TA). We first formulate the principles of layering and transition indep...
This paper describes an approach for conformance testing of mobile and distributed systems. The approach is based on kiltera — a novel, high-level language supporting the descri...
The complexity of embedded systems is increasing rapidly. In consequence, new verification techniques that overcome the limitations of traditional methods and are suitable for har...
Recently, a new approach to the symbolic model checking of timed automata based on a partial order semantics was introduced, which relies on event zones that use vectors of event o...
Visibly Pushdown Automata (VPA) are a special case of pushdown machines where the stack operations are driven by the input. In this paper, we consider VPA with two stacks, namely 2...
