title: System testing of Control System
body: <p>We are developing software for Control System of machinery. In the final product the software will be deployed on an ECU with real time operating system but we have the possibility to run the software on PC in emulation mode. Can we perform System level testing using the PC emulation mode only without the ECU hardware or it would be wrong to call that System testing? If it's not correct then what would be the right test level name to describe this test activity?</p>
