微处理器的验证工作是一项复杂而重要的工作。针对传统的FPGA验证在板级验证过程中存在不能快速定位错误和调试方法单一等问题,同时结合“龙腾R2”微处理器的验证需求,设计了“龙腾R2”微处理器的FPGA验证平台,在该验证平台上成功进行了指令和VxWorks操作系统的测试。实践表明该验证平台大大缩短了验证周期,整个验证平台原理清晰,结构简单,扩展灵活、方便。
Microprocessor validation is a complex and important task. Aiming at the problems of traditional FPGAs verification such as the inability to quickly locate errors and the single debug method in the board level verification process and combined with the verification requirements of the “Dragon V2” microprocessor, the FPGA verification platform of “Dragon V2” microprocessor is designed. The verification platform and the successful instruction and VxWorks operating system testing. Practice shows that the verification platform greatly shortens the verification cycle, the entire verification platform is clear in principle, simple in structure, flexible in extension and convenient.
