This paper presents the tools ALDEBARAN, CESAR, CESAR.ADT and CLEOPATRE which constitute a tool- box for compiling and verifying LOTOS programs. The principles of these tools are described, as well as their performances and limitations. Finally, the formal verification of the ret/REL atomic multicast protocol is given as an example to illustrate the(More)
In this paper we suggest numerical decision diagrams, a bdd-based data-structure for representing certain subsets of the Euclidean space, namely those encountered in veriication of timed automata. Unlike other representation schemes, ndd's are canonical and provide for all the necessary operations needed in the veriication and synthesis of timed automata.(More)
