What is HIL?

Hardware-in-the-loop (HIL) simulation is a type of real-time simulation used for testing complex embedded systems. It involves integrating actual hardware components with a simulated environment to emulate the system's operating conditions. This allows engineers to test and validate the hardware and software components of a system in a controlled and repeatable environment before deployment, reducing development time and costs and improving system reliability. HIL is commonly used in the automotive, aerospace, and defense industries for testing electronic control units (ECUs), flight controllers, and other critical systems.
