Safety systems

Evaluation of safety software

Ever since it was founded, ClearSy has applied its skills and technical expertise in modeling and engineering tools.

ClearSy’s activity centers on the constraints of operational safety. ClearSy aims at a wide range of partners, from industry to contractors as well as certification agencies responsible for specifiying, confirming, proving, or certifying their systems and software.

At the same time, ClearSy’s activities also involve safety management (safety plan, safety file) as well as the required safety analysis for systems or the component software.

From the Atelier B tool which it develops and distributes, ClearSy has acquired a complete mastery of formal methods which today provide it with an expertise in the highest level of software safety as well as the confidence of large contractors such as Alstom, Peugeot, DGA, Cybernetix, CEA, etc.

In the framework of the high safety levels required by the 61508, 50128, and DO178 standards, the use of formal methods is highly recommended.

Development of safety software

Because of the use of modeling techniques, ClearSy is innovative in the development of software packages.

To accomplish this, ClearSy bases its approach on the entire set of documents provided by the customer, expressed in natural language and including the specifications related to the software product. Formal methods allow the Company to model the latter while guaranteeing its conformity while also adapting it as much as possible to the constraints of the contractor.

Developing safety software involves ensuring its proper operation and the impossibility for the software to execute dangerous actions. It also implies a thorough and rigorous mastery of the software operation.

Therefore, ClearSy uses its knowledge to meet the highest requirements of safety software through safety instructions developed in a structured, clear, unequivocal, verifiable, testable, and maintainable manner, completely unambiguous as far as the documentation is concerned and at all stages of the development cycle.
