Validating the performance of C-V2X designs with emulation
Achieving the desired performance and communication quality of a cellular vehicle-to-everything (C-V2X) system requires application-level testing that integrates C-V2X scenarios with hardware-in-the-loop (HIL) systems. When performing V2X testing, building a real scenario is time-consuming and difficult to repeat in extreme cases. The driver’s safety is at risk, and efficiency is much lower. HIL simulation enables safe, accurate, and repeatable testing. The C-V2X HIL test enables developers to verify performance relative to the relevant Intelligent Transport Systems (ITS) stack, ensuring accurate communication to and from the vehicle.
Standards bodies, such as C2C Forum in Europe, SAE in North America, and C-SAE in China, define use cases for the test. The C-V2X HIL test requires software-based simulation using realistic traffic and RF congestion conditions for the host vehicle and all surrounding remote vehicles, as defined by use cases in the relevant standards. Emulations of realistic traffic conditions provide a rigorous test of actual vehicle system performance. Developers can easily identify and address issues or weaknesses in the technology or in the lab — before deployment in the real world.
C-V2X HIL test solution
C-V2X hardware-in-the-loop test requires simulation of the real-world conditions of C-V2X communications, enabling developers to validate the functionality and performance of the technology under various scenarios. The Keysight C-V2X HIL test solution, comprising the Keysight E7515B UXM 5G wireless test set and Keysight C8700200A UXM 5G application software, follows the evolving 3rd Generation Partnership Project (3GPP) C-V2X standard. The solution supports the mature C-V2X protocol stack and meets the requirements of protocol conformance testing.
