ARM and Esterel Technologies have announced their collaboration on a toolchain for safety-critical systems requiring IEC 61508 certification. Under the agreement, work has been done to ensure that Esterel SCADE Suite and ARM RealView Compilation Tools can be combined to provide a seamless software development flow, from modelling and code generation to compiling and debugging, for safety-critical systems in automotive, transportation and industrial control.

The SCADE Suite KCG has been certified for IEC 61508 at SIL3 level, the international standard covering functional safety of electrically-based, safety-related systems. The SCADE Suite automatically generates code that is compliant with IEC 61508, as well as the Motor Industry Software Reliability Association (MISRA) rules for software development in the C programming language. By using SCADE Suite together with ARM RealView Compilation Tools, an integral part of the RealView Development Suite and the RealView Microcontroller Development Kit, automotive system design engineers will be able to significantly reduce the time it takes to develop software, remove errors, and optimise the speed, memory and code size for ARM Powered embedded systems based on the Cortex-M3 and Cortex-R4 processors.

"Safety always comes first in the automotive industry," said Eric Bantegnie, president and CEO, Esterel Technologies. "SCADE Suite is a proven solution for generating and verifying IEC 61508-compliant code for safety-critical embedded systems. Through extensive testing, we have also verified that SCADE Suite and ARM RealView Compilation Tools together can vastly simplify the process of compiling and debugging code, and significantly accelerate our customers' time-to-market. This evidence is provided within the SCADE Suite Compiler Verification Kit (CVK)."

"From processors to system design tools, ARM is committed to helping our Partners build the most reliable, efficient embedded systems possible," said John Cornish, VP, Marketing, System Design Division, ARM. "Together with Esterel, we are providing a consistent environment for the development of safety-relevant software, using SCADE Suite for simulation and code generation along with RealView Compilation Tools for embedded systems based on the ARM Cortex-M3 and Cortex-R4 processor platforms."

The integrated software development flow from Esterel and ARM will complement the enhanced safety features of the ARM Cortex-M3 and Cortex-R4 processors. The Cortex-R4 processor in particular has been designed specifically for fault-tolerant automotive applications, featuring safety-critical features such as Error-Correction Coding (ECC) technology and a Memory Protection Unit (MPU).
