HighTec EDV-Systeme, Elektrobit, and Infineon Technologies have entered into a strategic collaboration to support the integration of the Rust programming language with AUTOSAR Classic basic software for Infineon’s AURIX™ TC4x microcontrollers. This partnership aims to support modern software development practices for safety-critical applications in the automotive sector.
As partners in Infineon’s Drive Core ecosystem, HighTec and Elektrobit are introducing a development bundle that includes Elektrobit’s EB tresos AutoCore and HighTec’s LLVM-based compiler, which supports both Rust and C/C++. The bundle, designed for the AURIX TC4x families, combines all required tools and software into one package, helping developers start working with Rust and AUTOSAR Classic more efficiently.
Rust’s memory safety and performance characteristics make it well-suited for developing functional safety applications in complex automotive electronic control units. The language addresses the growing need for cybersecurity and safety compliance in the context of software-defined vehicles and regulatory frameworks such as UN R155 and the EU Cyber Resilience Act. By integrating Elektrobit’s AUTOSAR Classic Basic Software with HighTec’s ISO 26262 ASIL D-certified Rust compiler, developers can incorporate Rust-based components within existing AUTOSAR environments. This enables a hybrid development model, allowing new Rust modules to run alongside legacy C/C++ code and supporting a smoother transition while adhering to safety standards.
The Drive Core software bundle for Infineon’s AURIX TC4x microcontrollers includes the necessary microcontrollers, the EB tresos configuration tool, Infineon’s TC4x Microcontroller Abstraction Layers (MCALs), as well as examples and tutorials to assist developers in creating AUTOSAR components in Rust. EB tresos has been enhanced to support Rust development more effectively, minimizing the need for unsafe code and enabling system-access code generation. It also integrates with static analysis tools like Clippy and supports automatic code formatting.
HighTec’s Rust and C/C++ compiler, based on the open-source LLVM framework, is optimized for Infineon’s AURIX TC3x and TC4x series. It is the first commercial Rust compiler tailored to these microcontrollers and supports architecture-specific functions. The compiler is recognized for its fast build system and advanced code optimization features, helping accelerate both development and safety certification processes.
Infineon continues to support innovation in automotive software through its ecosystem-based Drive Core platform, which provides foundational tools for application development. The company also maintains one of the most extensive MCAL portfolios in the industry.
Representatives from the collaborating companies commented on the development. Patrick Will, Senior Director of Automotive Software at Infineon, noted that Drive Core is intended to support innovation across the automotive sector. Florian Bartels, Senior Expert and System Architect at Elektrobit, stated that bringing Rust into the AUTOSAR Classic environment enhances development for modern ECUs. Mario Cupelli, CTO at HighTec, said that combining HighTec’s compiler with Elektrobit’s tools gives automotive suppliers and OEMs a complete solution for building efficient and safety-compliant software.
HighTec and Elektrobit are also organizing workshops and practical sessions to guide developers on how to implement Rust in AUTOSAR Classic projects.
Elektrobit is a global provider of embedded and connected software products and services for the automotive industry. With over 35 years of experience, Elektrobit’s software is used in more than 600 million vehicles. The company operates as a wholly owned subsidiary of Continental.
