Abstract: With the continuous development of the XR field, the demand for fully functional and highly complex XR chip systems is increasing. The growing scale and complexity of chips pose significant challenges to verification convergence. How to achieve convergence of key verification metrics before tape-out has become a critical challenge for verification engineers and project managers. To address this, an EMU full-scenario AVIP rapid iteration verification solution is proposed. The EMU platform adopts Cadence Palladium Z2, where AVIP adapts to the Palladium Z2 EMU environment based on Cadence VIP. It interfaces with protocols such as PCIe, MIPI, USB, and UART, while meeting requirements for simulation acceleration, data comparison and others. By applying this solution to XR chip systems, verification convergence efficiency is effectively improved, providing robust support for tape-out decisions
