# Verilog PCIe VCU108 Example Design
## Introduction
This example design targets the Xilinx VCU108 FPGA board.
The design implements the PCIe AXI lite master module, the PCIe AXI master module, and the PCIe DMA module. A very simple Linux driver is included to test the FPGA design.
* FPGA: xcvu095-ffva2104-2-e
## How to build
Run `make` to build. Ensure that the Xilinx Vivado components are in PATH.
Run `make` to build the driver. Ensure the headers for the running kernel are installed, otherwise the driver cannot be compiled.
## How to test
Run `make program` to program the VCU108 board with Vivado. Then load the driver with `insmod example.ko`. Check dmesg for the output.
