A Timed Extension for ALTARICA
نویسندگان
چکیده
In this work we present a timed extension of the AltaRica formalism [1, 2]. Following the work of [2], we extend the semantics of AltaRica to timed components and timed nodes. Moreover we also extend the priority mechanism of AltaRica to the timed case. Finally we give a translation of a Timed AltaRica specification into a usual timed automaton that can then be analysed by existing tools for checking properties of timed systems.

Hierarchical Modeling and Verification of Timed Systems in Timed AltaRica
In this paper we present a timed extension of the AltaRica language, Timed AltaRica, and describe the architecture of a compiler from Timed AltaRica to timed automata. We present the features of the language, namely modularity, hierarchical modeling and reuse of components during the specification phase, on an avionics example. Then, we use the compiler from Timed AltaRica to Timed Automata to ...
متن کاملSafety assessment of AltaRica models via symbolic model checking
AltaRica is a language used to describe safety critical systems that has become a de-facto European industrial standard for Model-Based Safety Assessment (MBSA). However, even the most mature tool for the support for MBSA of AltaRica models, i.e. Dassault’s OCAS, has several limitations. The most important ones are its inability to perform many analyses exhaustively, severe scalability issues, ...
متن کاملThe AltaRica data-flow language in use: modeling of production availability of a multi-state system
This article presents an application of the AltaRica Data-Flow language to the assessment of the average production of a production line throughout a period of time. Its contribution is twofold. The problem is described. Modelling difficulties are pointed out. Solutions are proposed via the use of the AltaRica Data-Flow language. The ability of this language to represent complex systems is demo...
متن کاملSymbolic Model Checking and Safety Assessment of Altarica models
Altarica is a language used to describe critical systems. In this paper we present a novel approach to the analysis of Altarica models, based on a translation into an extended version of NuSMV. This approach opens up the possibility to carry out functional verification and safety assessment with symbolic techniques. An experimental evaluation on a set of industrial case studies demonstrates the...
متن کاملRaffinement Altarica Pour L’etude De Systemes a Differents Niveaux De Detail Altarica Refinement for Heterogeneous Granularity Models Analysis
Résumé Nous définissons une notion de raffinement pour les modèles AltaRica afin de permettre l’analyse de la sécurité de systèmes décrits à différents niveaux de détails. Nous montrons comment s’assurer automatiquement qu’un modèle raffine un autre à l’aide de l’outil de vérification Mec V. Nous présentons deux résultats théoriques, l’un permet de vérifier le raffinement en se focalisant sur u...
