Testing complex electronic control units (ECUs) is difficult, and as the complexity increases, the number of combinations of tests required to ensure correct functionality and response increases exponentially. That is why many companies now use hardware-in-the-loop (HIL) testing. HIL testing can be used throughout the development cycle to reduce development time and improve the effectiveness of testing. Hardware-in-the-loop systems allow you to simulate sensors, actuators and mechanical components that will be used with an ECU long before you prototype the final system.
HIL systems allow extensive fault insertion that would not be practical on the real system. The types of faults that you can insert include open circuits; high resistance circuits; and short circuits from channel to channel, channel to ground, and channel to battery.
