: This paper proposes a development process for interactive systems based both on verification and validation methods. Our approach is formal and use at first the B Method. We show...
Behaviour of systems is described by formal languages: the sets of all sequences of actions. Regarding ion, alphabetic language homomorphisms are compute abstract behaviours. To a...
With the increasing complexity of today's embedded systems, there is a need to formally verify such designs at mixed abstraction levels. This is needed if some compoe describ...
Designing safety-critical systems is a complex process, and especially when the design is carried out at different f abstraction where the correctness of the design at one level i...
This paper presents the real-time model checker RAVEN and related theoretical background. RAVEN augments the efficiency of traditional symbolic model checking with possibilities to...
