What is HILs?

HILs, or Hardware-in-the-Loop simulations, are a type of real-time simulation used to test embedded systems. They work by creating a virtual environment that mimics the system's real-world inputs and outputs. This allows engineers to test the embedded system in a controlled environment without the need for physical prototypes. They are commonly used in the automotive, aerospace, and industrial automation industries to test things like engine control units, flight control systems, and robotics.
