32位RISC微处理器FPGA验证平台设计与实现

Design of FPGA verification platform of 32 bits RISC microprocessor

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。

The verification of microprocessors is a complex but important job.Aiming at the problems existed in traditional FPGA board verification,such as it can＇t find the erros quickly and the debug method is simplex,also link with the verification requirement of ＂LongTium R2＂ microprocessor,a FPGA verification platform is designed,on which the instruction and VxWorks operating system have been tested.The result indicates that the platform can shorten the verification cycle greatly,the whole system is very transparent,and its structure is so simple that its upgrade might be fairly flexible and convenient
