The client is a British automotive manufacturer of luxury and racing cars. They needed to develop a high-efficiency, compact DC-DC converter based on an 800-400V architecture for the next generation of hybrid supercars. Given the safety-critical nature of the application, the converter had to be engineered with a complex high-voltage power electronics architecture, compliant with stringent functional safety standards and robust cybersecurity measures, ensuring reliable performance in a high-performance automotive environment.
eInfochips delivered a turnkey solution encompassing bare-metal application software development on the Infineon AURIX TC3xx MCU (Microcontroller Unit) platform, functional safety engineering to ASIL B, and automotive cybersecurity implementation as per ISO 21434. The engagement covered the complete software lifecycle from sensor acquisition, state handling, and diagnostics, through safety concept development and cybersecurity controls, to integration testing, Hardware-in-loop testing, fault injection, and test automation.
Key Highlights
The engagement delivered measurable outcomes: $50–$100K saved by avoiding a commercial AUTOSAR stack, a 40% potential reduction in development efforts through modular and reusable software frameworks, and a 60% reduction in manual testing efforts through automated test scripts while achieving both ISO 26262 ASIL B and ISO 21434 compliance.
