LCHIP project (Low Cost High Integrity Platform) will ease development of safety critical systems and software up to SIL4, the highest Safety Integrated Level.

LCHIP project (Low Cost High Integrity Platform) will ease development of safety critical systems and software up to SIL4, the highest Safety Integrated Level.
LCHIP platform is a combination of a B method (formal method) Integrated Development Environment and a secured runtime platform able to execute software in real-time. The IDE generates and mathematically proves critical software source code in an automated process. When it comes to simple algorithms, the IDE extends functionalities of Atelier B (software to develop in B method). The low cost runtime platform, which runs software from the IDE, is secured in real-time in order to provide an optimum safety. “Such a combination reduces ten times the cost of the secured platform” Thierry Lecomte, expert in Atelier B at ClearSy explains.
