Who we are

The ClearSy company

ClearSy was founded on January 1st, 2001 by a group of engineers that had industrialized the formal modeling tool referred to as Atelier B, used in the rail transport industry to create safety software.

Clearsy was created on the basis of two principal objectives:

  • To develop formal type methods and tools
  • To develop software and systems that justify the use of formal methods

Today, ClearSy employs approximately a hundred engineers, consultants and experts in the regions of Aix en Provence, Paris, Lyon and Strasbourg. ClearSy engineers are skilled in various engineering fields (systems, mechanics, electronics, software, operational safety). They have IT tools and an electronic laboratory to create prototypes and conduct trials. Collaborations with laboratories and industrial partnerships ensure the production of the various system components (sensors and interfaces).

 

Clearsy is principally involved in two activities:

  • Tools and Methods: development of tools: Atelier B, CompoSys, Brama, development of methods and prototypes within industrial R&D and European projects, development of specific industrial engineering tools
  • An engineering activity based on the realization of projects committed to achieving results in the design and/or validation of systems and software, and a technical support activity in the formal field and the field of operational safety.

Clearsy’s originality lies in its expertise in Systems, Software and Operational Safety, as well as its mastery of formal methods.

These are used:

  • In the specification phase to validate specifications, demonstrate coherence and represent the system in the form of a digital and graphical model
  • In the realization phase for safety software to demonstrate that the software complies with its specifications and to prove that no coding error exists.

Clearsy clients include major industries and originators, essentially in the field of rail and road transport. Current Clearsy projects essentially involve the realization of safe systems to comply with Standards 61508, 50126, 50128 and 50129.
