As the number of embedded systems has grown regularly over the past decades, the development and certification costs of safety-critical software has increased accordingly. For the aeronautics industry, certification activities are covered by DO-178C, which provides guidance for developing airborne software; and its companion document DO-330 covers the qualification of tools used for the development of such software. In this paper, we present ASTERIOS , a solution for the design, generation and execution of safety critical real-time applications; then we present the certification strategy we advocate for systems developed using our technology. This strategy relies on the use of an automated verification tool called ASTERIOS Checker , qualified in accordance with DO-330. This paper presents the technology behind the code generation engine of ASTERIOS and the verification activities automated by ASTERIOS Checker. It shows how the use of such an automated, qualified tool enables to benefit from design abstractions and relatively complex code generation engines while developing certified systems at the highest level of certification.
