The development of high-integrity systems within the automotive industry is characterized by demonstrating compliance with ISO® 26262, an international standard for road vehicle functional safety. ISO 26262 classifies functions in automotive safety integrity levels (ASIL) from A to D – that is, from least to most stringent. OEMs and Tier-1 suppliers are adapting their ECU development processes to use Model-Based Design with ISO 26262.
Embedded Coder®, Simulink® model verification tools, and Polyspace® code verification tools are certified by TÜV SÜD as qualified tools according to ISO 26262 for ASIL A-D. The qualifications are based on an automated, application-specific verification workflow. It supports back-to-back model and code testing, as highly recommended by ISO 26262-6 for ASILs C and D, using the processor-in-the-loop (PIL) simulation mode in Simulink. As such, engineers can leverage coder and compiler optimizations, including processor-specific code generated by Embedded Coder, to produce the fast and memory-efficient software needed for mass production ECUs. In addition to C code generation, Embedded Coder ISO 26262 tool qualification use cases include its AUTOSAR and C++ code generation capabilities.
The workflow documentation, TÜV SÜD certificates and reports, test suites, and additional certification artifacts are provided in the IEC Certification Kit (for ISO 26262).

“Without Model-Based Design, we would have needed at least 30% more time to develop and certify the ESCL application software. We saved time and effort by generating efficient code that satisfied all our speed and memory requirements.”Cheng Hui, platform and process manager, KOSTAL
"We leveraged MathWorks consultants to apply Model-Based Design for ISO 26262 on our new Integrated Restraints and Braking Controller (IRBC) developed with Simulink, Stateflow, Simulink Design Verifier, and Embedded Coder for production code generation and verification."Rich Rakes, Lead Engineer, Autoliv
