From the project
Hardware-In-the-Loop (HiL ⛰️) for high-quality validation 🧪 everywhere 🚀
Hardware-in-the-Loop, or HiL (sometimes HitL), is a way to continuously validate your hardware and firmware together. By connecting actual hardware to virtual test scenarios, HiL enables thorough testing of embedded systems, control units, and firmware under realistic conditions without the risks and costs of full physical testing.
HiL testing catches integration issues early, accelerates development cycles, and ensures robust system performance before deployment. Typically the domain of the most sophisticated automotive and aerospace companies, this HiL suite is now for all 🚀.
