The new solution supports the Rust programming language and combines the HighTec Rust Compiler, qualified according to ISO 26262 ASIL D, with ST's Stellar 28 nm (32.2 miles) microcontroller series, certified to the same safety standard. Rust is gaining increasing importance in the automotive industry due to its high safety and reliability characteristics.

Reduce time-to-market

Automakers are under significant pressure to shorten development cycles and meet evolving safety standards. Thanks to the cooperation between ST and HighTec, they receive a robust, safety-compliant solution for developing automotive software. The integration of the ASIL D-qualified HighTec Rust Compiler with the Stellar MCU family accelerates the development of safety-critical systems, shortens time to market, and ensures strict compliance with automotive safety requirements.

Why Rust?

Rust, with its memory safety, performance, and reliability, is becoming increasingly popular in the development of safety-critical automotive systems. The close collaboration between ST and HighTec ensures that developers can integrate Rust alongside their C/C++ codebase into their safety-critical projects with Stellar, accelerating the development of safety-relevant systems—this shortens time to market and ensures compliance with automotive safety requirements.

Rust includes features for the safety of memory, process threads, and data types, providing particular resilience for critical vehicle systems. Rust's runtime efficiency in terms of execution time and memory usage is comparable to C/C++. These properties significantly lower the costs of software development and maintenance, shorten development cycles, and enhance safety.

The HighTec compiler for C/C++ and Rust for automotive applications leverages Rust's safety features and allows hybrid development with existing C/C++ code to develop secure automotive software for software-defined vehicles.

ST's Stellar automotive MCUs are based on Arm Cortex-R52+ cores and a safety-oriented hardware architecture. The 28 nm (32.2 miles) MCUs have an ISO 26262 ASIL D certification, issued in early 2024. Additionally, the Stellar MCUs comply with the cybersecurity standards of ISO 21434 and the requirements of UN155.

The HighTec Rust Compiler complements the already established HighTec C/C++ Compiler Suite. Both are qualified to the highest safety level ISO 26262 ASIL D and enable automotive software developers to fully leverage the high reliability and performance features of the Stellar MCUs. The toolchain is based on the open-source technology LLVM and allows for hybrid development of Rust code alongside C/C++ code. (se)
