This presentation explores how Agentic AI and Hardware-in-the-Loop (HIL) can enable the next generation of autonomous automotive validation. The session will demonstrate an end-to-end approach where AI agents interpret requirements, generate test scenarios and scripts, analyze coverage, orchestrate HIL resources, execute regression tests, and intelligently analyze failures. It will introduce tool-agnostic automation using standardized XIL interfaces across heterogeneous HIL environments, along with AI-driven issue triaging and continuous traceability.
