Krono-Safe’s Asterios integrated real-time operating system, mixed with Ansys Scade Suite embedded software, gives customers a new first-to-market solution, Ansys said.

“To build safer airplanes, while optimizing fleet maintenance and cost, new aerospace computers must be built to handle both traditional safety critical control and command applications, as well as modern maintenance and monitoring capabilities,” Ansys said. “[This new solution] provides aerospace customers a real-time integration flow suitable for safety-critical avionics multi-rate applications on single or multi-core platforms. This avionics automated design flow combines Scade Suite for safe and automated development of application software and Asterios for safe and automated real-time integration, extended to multi-core platforms.”

Safran Electronics and Defense has selected the solution, Ansys said, to accelerate the software development process for critical avionics computers. The company’s plan is to apply them to command-and-control computers for aerospace engine and brake control.

"Dependability is the keystone to real-time system development in the avionics domain," said Jean-Christophe Jammes, research and technology program manager at Safran Electronics and Defense. "Ensuring a high-level of safety during the real-time integration phase of a multi-rate application today is very long and tedious work, involving tens of people over many months. The work achieved so far by Krono-Safe and Ansys, and used by Safran engineers in the scope of the S3P program, proves that it is possible to significantly reduce this effort with the automation of new activities such as the scheduling and partitioning, while ensuring a high-level of safety by construction."

The S3P (Smart, Safe and Secure Platform) research and development project aims to quickly deploy and exploit internet-of-things devices and other applications in an economic fashion. Krono-Safe said Safran is currently assisting with Do-178C certification.
