摘要: 隨著XR領域的不斷發展,市場對全功能和更高性能的復雜XR芯片系統需求越來越強烈。需求傳導到芯片設計環節,呈現出芯片規模和復雜度增加的態勢,給芯片驗證收斂帶來的挑戰也同時不斷增大。如何在投片前做到關鍵指標驗證收斂,是每個芯片工程師和項目經理面對的難題。在XR芯片研發領域,為了解決這一難題,提出EMU全場景AVIP快速迭代驗證方案,其中EMU設備采用Cadence Palladium Z2,AVIP在Cadence VIP的基礎上,適配Palladium Z2 EMU環境,對接PCIe、MIPI、USB、UART等不同接口,并滿足仿真加速、數據比對等需求。通過在XR芯片系統中EMU全場景AVIP快速迭代驗證方案的應用,有效提升驗證收斂效率,為芯片的成功交付做到了有力支撐。

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
