摘要： 由于片上系統(tǒng)芯片(System on Chip，SoC)規(guī)模越來越大，軟件仿真速度在一些大的場景測試用例下已經(jīng)很難滿足驗證計劃時間的要求。現(xiàn)場可編程門陣列(Field Programmable Gate Array，F(xiàn)PGA)原型驗證平臺容量的限制，以及需要修改時鐘樹等特性導(dǎo)致FPGA平臺并不適合做功耗/性能評估。基于Emulator平臺的仿真加速以及功耗/性能評估已經(jīng)成為一種趨勢?？梢允褂肊mulator的加速驗證知識產(chǎn)權(quán)(Accelerated Verification Intellectual Property，AVIP)替換軟件仿真用的驗證知識產(chǎn)權(quán)(Verification Intellectual Property，VIP)來做仿真加速。以及使用高級微控制器總線結(jié)構(gòu)(Advanced Micro-controller Bus Architecture，AMBA) AVIP來模擬或者監(jiān)控總線的傳輸，結(jié)合其他工具可以用來做功能/功耗/性能相關(guān)的驗證工作，大大加速了芯片相關(guān)開發(fā)驗證的進(jìn)程。

Abstract： Due to the increasing scale of the chip, the EDA simulation speed has been difficult to meet the schedule requirements in some large scene cases. At the same time, the capacity of the FPGA prototype verification platform is limited, and some clock trees need to be modified and are not suitable for power/performance evaluation. Simulation acceleration and power analysis and performance evaluation based on Emulator platform have become a trend. Based on the emulator AVIP to simulate or monitor related bus transaction can be used to do the related work of function/power/performance which can greatly accelerated the process of chip development. The test cases developed based on MIPI AVIP for verifying MIPI or using MIPI to verify the internal image processing module achieves dozens of times of acceleration ratio and greatly improves the simulation speed. As well as using AVIP to simulate and monitor the behavior of related modules，can get the netlist power data and performance data. It has made an important contribution to the functional verification and power/performance optimization of the chip.
