A Toolbox For The Verification Of LOTOS Programs

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 practical use of the tool- box.
