HighTec’s Latest C/C++ Compiler Achieves ISO 26262 ASIL D Certification for Infineon AURIX™
This C/C++ certification complements HighTec’s existing Rust certification, enabling hybrid safety-critical automotive software development on AURIX™ TC4xx and TC3xx
Saarbruecken/Germany, 10 July 2025 – HighTec EDV-Systeme GmbH announces 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 HighTec’s continuous 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 alongside 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 both C/C++ and Rust compiler tools, HighTec enables 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.
HighTec’s automotive-grade compilers for C/C++ and Rust is built on the cutting-edge LLVM open-source technology, offering developers fast build times and robust code optimization. The recent ISO 26262 ASIL D certification for the C/C++ compiler further strengthens HighTec’s functional safety portfolio. As the first to deliver an ISO 26262 certified Rust compiler for Infineon AURIX, HighTec now enables 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, HighTec’s unified compiler technology offers a seamless solution for developers targeting Infineon’s AURIX™ TC4xx and TC3xx microcontrollers. The interoperability between the two languages enables 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 ensures consistent output, preserves existing C/C++ investments, and maintains 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.”
