中文摘要：

作为描述FPGA硬件资源的结构描述文件,不仅是VPR布局布线工具的重要组成元素,而且是FPGA硬软件工程师相互沟通的桥梁。阐述了VPR布局布线的工作流程,对VPR的FPGA结构描述文件进行解析,以正确地表示FPGA芯片内部的通道、开关、逻辑资源、布线资源等结构信息。进而,以可配置逻辑块CLB和Virtex-6的Slice结构为例,分别给出了相应的FPGA结构描述文件,重点讨论了逻辑单元块和内部连接的XML代码。FPGA结构描述文件正确地被描述和解析,有助于开展FPGA结构在内存物理中的存储和转换等后续研究工作。

英文摘要：

As the communication channel between the hardware engineer and software engineer,FPGA architecture description file is crucial component of Versatile Placement and Routing tool（VPR） which is used to describe FPGA hardware resources.We present the placement and routing process of VPR.We also parse the FPGA architecture description file of VPR to make sure that we can accurately denote channels,switches,logic resources,routing resources and others architecture information inside the FPGA chip.Furthermore,we give the corresponding the FPGA architecture description files of configurable logic block and Virtex-6 slice.We also discuss the XML codes of physical blocks and intra-block interconnects.It is important to do research on its memory storage format and conversion that we can accurately parse the FPGA architecture description file.
