According to the PCIe protocol

the basic structure of the PCIe bus is introduced. On this basis

a PCIE interface that can be applied to the FPGA is designed

and the interface conversion is completed according to the actual user requirements. At the same time

the programmability design is convenient for the user to quickly configure the interface

and the functions applied to the FPGA are introduced. Code specification. Finally

based on the UVM build verification platform

the PCIE verification is completed

and finally the PCIe interface is applied to the FPGA.
