The presentation introduces a structured approach to efficiently test ECUs from a software-in-the-loop (SIL) environment to real hardware. Initially, before the base software is fully developed, the ECU operates in a virtualized environment with generated base software. Later on, the ECU integrates the productive base software, still running in a virtual environment with a simulated vehicle bus. In the final stage, it connects to a physical vehicle bus for hardware-in-the-loop (HIL) testing. The talk covers key software capabilities that enable a smooth transition from SIL to HIL, ensuring efficient testing and improved software quality.

• Different levels of ECU virtualization and their role in testing
• Test cases reusable across virtualization stages, including real hardware
• Early testing quickly identifies and localizes issues
• Tool requirements for virtualization and testing from SIL to HIL
