Latest C/C++ compiler achieves ISO 26262 ASIL D certification for Infineon AURIX

HighTec EDV-Systeme GmbH has announced the ISO 26262 certification for functional safety of its latest TriCore C/C++ compiler, approved up to ASIL D by TÜV NORD. This certification applies to the latest version, 9.1.2, and reinforces its ongoing commitment to functional safety in embedded systems. This milestone particularly benefits automotive software developers working on Infineon’s AURIX TC4xx and TC3xx MCUs. This certification, along with the Qualification Kit, provides developers with greater flexibility and significantly reduces the time and effort required to qualify safety-critical automotive applications. With certification now covering C/C++ and Rust compiler tools, the company allows software engineers to adopt a hybrid development approach, combining safety-qualified legacy C/C++ code with modern, memory-safe Rust code while fully meeting the highest safety standards.

The company’s automotive-grade compilers for C/C++ and Rust are built on the cutting-edge LLVM open-source technology, offering developers fast build times and robust code optimisation. The recent ISO 26262 ASIL D certification for the C/C++ compiler further strengthens its functional safety portfolio. As the first to deliver an ISO 26262-certified Rust compiler for Infineon AURIX, HighTec now allows automotive software developers to adopt a unified safety-certified toolchain technology for hybrid software designs that combine legacy C/C++ with modern, memory-safe Rust code.

By supporting both C/C++ and Rust, the company’s unified compiler technology offers a seamless solution for developers targeting AURIX TC4xx and TC3xx MCUs. The interoperability between the two languages allows developers to gradually integrate Rust into existing projects, such as isolating cybersecurity-critical modules in memory-safe Rust while maintaining legacy functionality in C/C++. Its common LLVM backend, linker, and build infrastructure ensure consistent output, preserve existing C/C++ investments, and maintain system-wide integrity, without needing to split toolchains, workflows, or further qualification efforts.

“Our mission is to be the premium one-stop tool provider for safety-critical automotive applications, supporting developers working on AURIX platforms”, says Mario Cupelli, CTO at HighTec EDV-Systeme. “With ISO 26262 certification now for both our latest C/C++ and Rust compilers, we deliver a unified, safety-certified toolchain for AURIX platforms that bridges the gap between proven legacy and modern secure-by-design code. This reduces qualification overhead, simplifies hybrid development and enables customers to focus more resources on advancing automotive innovation for software-defined vehicles.”
