In safety-critical fields such as automotive, aerospace, and medical devices, system robustness directly determines whether products can maintain safe operation under abnormal conditions. Fault Injection Testing actively creates abnormal scenarios to verify the system’s fault tolerance capabilities. This article focuses on the technical points and implementation process of fault injection testing within the Simulink environment. … Read more
In the wave of automotive electronics transforming into “software-defined vehicles”, embedded software testing is upgrading from the traditional “verification phase” to a core competitive advantage that determines vehicle functional safety and user experience. When the code volume of a smart car exceeds 100 million lines, how can we build a reliable testing system within a … Read more
This system focuses on communication-related functions for real vehicles, conducting a rapid functionality survey. For IO operations, such as switching sensors, reminders are provided through a “popup + voice prompt” method, achieving semi-automation. Before the ECU is installed in the vehicle, we need to find ways to conduct HIL testing, such as basic functional logic … Read more
Today’s vehicle manufacturing has become extremely complex due to the diversity of electronic devices, software, and sensors. Additionally, many subsystems are not developed by the vehicle manufacturers themselves. Therefore, OEMs and suppliers face challenges in collaborative development. In this free webinar, Guanglei Zhou from VI-grade will showcase how Hardware-in-the-Loop (HiL) testing can assist OEMs in … Read more
In the automotive electronics development industry, the software development V-model derived from ISO26262 is increasingly accepted by developers. A crucial part of the V-model is HIL (Hardware-in-the-Loop) testing. Depending on the specific product form, the specifics of the V-model may vary, but it generally follows the overall process of requirements, design, and verification. For the … Read more
