Hardware In The Loop Testing
You can also use hil to determine if your physical system plant model is valid.
Hardware in the loop testing. The solution must provide comprehensive testing without the burden of using an assembled final product in the field. For example the device under test dut may have a series of sensors that require excitation. More about hardware in the loop hil allows embedded controllers to be tested with actual hardware components that simulate real world conditions thus facilitating parallel development and faster time to market. Hil simulation shows how your controller responds in real time to realistic virtual stimuli.
Hil simulation provides an effective platform by adding the complexity of the plant under control to the test platform. These mathematical representations are referred to as the plant simulation. Hil operates by testing ecus in a closed loop system with components that are simulated in a virtual environment so that they can be thoroughly tested without needing to have the complete product available. Hardware in the loop simulation or hwil is a technique that is used in the development and test of complex real time embedded systems.
Hardware in the loop hil simulation is a type of real time simulation. You use hil simulation to test your controller design. By allowing ecus under test to interact with a simulated use case you are free to test early and often to uncover as many software defects as possible. The complexity of the plant under control is included in test and development by adding a mathematical representation of all related dynamic systems.
Hardware in the loop testing takes automated testing to a new level by adding extra stimuli to simulate a real world application.
