手机智能卡高效可重用SoC验证平台设计

Design of Efficient and Reusable SoC Verification Platform for USIM Card

大规模系统芯片的设计必须依靠完整的验证来保证其正确性。高效、可重用的验证平台是必需的。该文采用便于调试的独特内存映射方式,将实时、多任务的VxWorks嵌入式操作系统应用于验证平台。该平台可对AMBA VIP的总线功能模型命令进行解释,实现测试用例的可重用。通过设计AHB总线到EC总线的桥接,实现验证平台对AMBA总线系统与EC总线系统的兼容。该平台在基于COS操作系统的手机智能卡芯片验证中得以应用。

The validity of System on Chip（SoC） depends on thorough verification. Efficient and reusable verification platform is necessary. The real-time and multi-task embedded operating system VxWorks is applied in this platform. It adopts unique memory mapping technique for convenient debug. Based on the interpretation of the BFM commands in AMBA VIE this platform fulfils reusability of testcase. Through the bridge between AHB and EC, it is compatible in SoC based on AMBA bus or EC bus. This platform is applied in the verification of USIM IC which uses COS operating system.
