XiL is a test & validation system that combines the capabilities of HiL, SiL and MiL (Hardware in the Loop, Software in the Loop and Model in the Loop). It can be applied to a conceptual model, a running (emulated) piece of software or a combination of real hardware controllers and its surroundings with a simulated plant.
Effective simulation helps virtualize the environment for the controller under test. The controller „thinks” that it is operating within the real product, while in reality most of the controller’s surroundings are simulated.
It is crucial to have a carefully selected test framework in place as it provides means for utilizing the system in a fully automated way, 24/7, while delivering repeatable and consistent results. Test scripts have to be clear and precise so that they can be accepted as part of the qualification process.
Since the XiL systems can combine hardware, virtual hardware and software, they usually come in the form of one or more testbenches that can be placed in a laboratory. Sometimes they are also equipped with dedicated test hardware like failure injection modules, custom interfaces etc.
Independent perspective. Quick ramp-up. Cost efficiency. Expertise and specialization. Flexibility and Scalability. These are just some of the reasons why it is a good idea to leave test scripting and testing in expert hands.
The answer is: Yes, if
