Abstract. We present a symbolic reachability analysis approach for B that can provide a significant speedup over traditional explicit state model checking. The symbolic analysis is implemented by linking ProB to LTSmin, a high-performance language independent model checker. The link is achieved via LTSmin's Pins interface, allowing ProB to benefit from LTSmin's analysis algorithms, while only writing a few hundred lines of glue-code, along with a bridge between ProB and C using ØMQ. ProB supports model checking of several formal specification languages such as B, Event-B, Z and Tla + . Our experiments are based on a wide variety of B-Method and Event-B models to demonstrate the efficiency of the new link. Among the tested categories are state space generation and deadlock detection; but action detection and invariant checking are also feasible in principle. In many cases we observe speedups of several orders of magnitude. We also compare the results with other approaches for improving model checking, such as partial order reduction or symmetry reduction. We thus provide a new scalable, symbolic analysis algorithm for the B-Method and Event-B, along with a platform to integrate other model checking improvements via LTSmin in the future.

“…Regarding this point, there was a study that compared cases where B Method is used with a case where an informal method (SDL) is used [16]. It reported decrease in overall development time in 30-50% (depending on the way B Method is used) due to remodelling work required to counteract errors due to misspecification in the SDL case.…”

SUMMARYAs a variety of digital services are provided through networks, more and more efforts are made to ensure dependability of software behavior implementing services. Formal methods and tools have been considered as promising means to support dependability in complex software systems during the development. On the other hand, there have been serious doubts on practical applicability of formal methods. This paper overviews the present state of formal methods and discusses their applicability, especially focusing on two representative methods (SPIN and B Method) and their recent industrial applications. This paper also discusses applications of formal methods to dependable networked software.

La méthode B, ainsi que sa progéniture Event-B, sont des méthodes formelles utilisées pour le développement de systèmes informatiques dont l'exactitude doit être formellement établie. Un grand atout d'Event-B est la plate-forme RODIN, qui est basée sur Eclipse et qui peut être étendue à l'aide de plug-ins. Dans cet article, nous présentons deux plug-ins pour RODIN : un outil d'animation ainsi qu'un outil d'aide à la preuve interactive, appelé un contre-prouveur (disprover). Les deux plug-ins ont été implémenté à l'aide de l'outil PROB et d'une traduction d'Event-B vers B classique. Avec nos outils, RODIN devient donc une plate-forme où l'utilisateur peut éditer, animer, prouver et contre-prouver des modèles d'une manière intégrée. ABSTRACT. The B-method, as well as its offspring Event-B, are both formal methods used for the development of critical computer systems whose correctness has to be formally established. Event-B now spurs the RODIN platform, which is based on Eclipse and can be extended via plug-ins. In this paper, we present two such plug-ins; one for animation and one for interactive proof support, called a disprover. Both plug-ins are based on the PROB tool as well as a translation of Event-B to classical B. With our new plug-ins, RODIN has now become a platform where a user can animate, prove, disprove formal models in an integrated fashion.
