Software-first vehicles require both development speed and high quality, even as the complexity and scale of development tend to increase. In this situation, MBD (model-based development, model-based design) is used to improve development efficiency, and AUTOSAR-compliant development is used to improve software reusability and compatibility. Static code analysis is essential for the shift-left of these developments, and automation including testing by CI tools is effective. This seminar will introduce the key points to ensure safety & security and improve quality and release cycles for various hand-written and automatically generated codes in MBD.
