Abstract: In FPGA design process, architecture modelling and analysis are of high significance. Architecture modelling means, for a specific FPGA, designer will apply language description to describe the components such as configurable logic blocks, switch boxes, routing resources and so on. After abstracting the FPGA architecture，based on the description file, design software will extract the parasitic parameters and information in order to place and route. VPR is a universal open-source tool for placement and routing. This paper has investigated FPGA architecture properties via VPR tool, and in accordance with the testing result, the performance could be estimated, which would be meaningful to provide a direction of architecture setting in practice.
