NI HIL and SDV Architectures

Hardware-in-the-Loop (HIL) testing is a critical methodology for the validation and verification of embedded control systems. HIL enables engineers to simulate real-world conditions and test system behavior safely, efficiently, and repeatedly. As vehicles become more complex and software-defined (SDV), the importance of scalable, reliable, and maintainable HIL platforms has grown significantly.

Recent industry trends for vehicle development and test such as “Shift to Left” have also introduced further complexities relating to cloud integration and software validation workflows. An effective modern HIL solution must be highly modular and use connected approaches so that reuse between cloud-based SIL platforms and HIL systems are seamless. This approach starts to be backed also by standardization bodies such as the NCAP and Euro NCAP which see the advantage of enabling virtual testing.
