System under test – from software to virtual ECU The system under test (SUT) is the focus of every test because it is precisely the software that will later have to prove itself on an ECU in real-world use. The Software-in-the-Loop (SIL) tests run completely without ECU hardware, which leads to many advantages, e.g., lower costs, easy scalability in the cloud, etc. But can realistic operating conditions even be represented without hardware?
