CPU卡虚拟原型验证平台设计

DESIGNING VIRTUAL PROTOTYPE VERIFICATION PLATFORM FOR CPU CARD

针对CPU卡设计规模小以及设计时间和成本有限等特点,选择合适的片上总线互联结构,设计一套虚拟原型验证平台。介绍虚拟原型验证平台的原理,着重分析采用AHB-lite片上总线结构能够极大地减小CPU卡设计的复杂度。运用搭建的CPU卡虚拟原型验证平台,对CPU卡的架构和自主设计的IP模块进行测试,并在实际的物理原型验证平台上对整个架构进行测试。测试结果表明设计的虚拟原型验证平台可以切实地减少设计的时间和成本。

In light of the small scale,limited time and expenses of CPU card design,by selecting a proper bus interconnection structure on chip we design a set of virtual prototype verification platform. The principle of virtual prototype verification platform is introduced in the paper,the highlight is put on analysing the use of chip bus structure of AHB-lite which can dramatically reduce the complexity of CPU card design. The constructed virtual prototype verification platform of CPU card is employed to test the architecture of CPU card and the selfdesigned IP modules,and the whole architecture is tested on practical physical prototype verification platform as well. Test results indicate that the designed virtual prototype verification platform can substantially reduce the design time and expense.
