In the field of real-time control applications, validation relies on a precise knowledge of the temporal characteristics of the used data such as delays and loss rates. These data are provided by a dedicated software called the driver. Consequently, it is necessary to evaluate the impact of the driver on the QoS (Quality of Service) of the data. This work(More)
Model checking is an effective technique for uncovering subtle errors in concurrent systems. Unfortunately, the state space explosion is the main bottleneck in model checking tools. Here we propose a state space reduction technique for model checking concurrent programs written in C. The reduction technique consists in an analysis phase, which defines an(More)
Verifying software systems automatically from their source code rather than modelling them in a dedicated language gives more confidence in establishing their properties. Here we propose a formal specification and verification approach for concurrent C programs directly based on the semantics of C. We define a set of translation rules and implement it in a(More)
Developing embedded real-time systems based on the TT paradigm is a challenging task due to the increasing complexity of such systems and the necessity to manage, already in the programming model, the fine-grained temporal constraints and the low-level communication primitives imposed by the temporal firewall abstraction. In embedded systems, high-level(More)
—Nous nous intéressons dans ce papier à l'automatisation de la traduction d'un code source C vers un modèle écrit dans le langage de spécification TLA+. Nous proposons alors un outil C2TLA+ pour automatiser le passage d'un code source C vers un modèle écrit dans un langage combinant une logique temporelle avec une logique des actions afin qu'il soit vérifié(More)
