Efficient HIL Testing for Safety-Critical Embedded Systems
Systems with functional safety can be very different in terms of their requirements and effects. If the torque switch-off of a drill fails, you can injure your wrist – the effects of a defect railway barrier are much more drastic.
In both cases, the security requirements must be tested very well and a process is needed that can demonstrate the structured approach and identify and eliminate quality gaps.
Unit tests are a good start, but to test critical functions, you need more than just software tests. For example, if you want to test the motor shutdown at critical temperatures, you need to test the complete shutdown path including the electrical signals, drivers and all software components involved. This can be achieved very well with hardware-in-the-loop (HIL) tests. However, HIL tests are often very time-consuming and difficult to automate. For this reason, the tests are carried out rarely and late in the development process.
In the presentation, I will show a fully automatable HIL test approach that can be carried out within minutes after each software change. By fully simulating the environment, a large number of safety-relevant functions can be tested automatically on the unmodified software on the right microcontroller.
