https://fpgawiki.intel.com/uploads/3/3a/C4gx15_starter_qsys_pcie_gen1x1.zip I use this example to test PCIe.

I want to test the transmission speed between PC and FPGA via PCIE. It need the help of DMA. I use this example but I find that the DMA (can be seen in QSYS) do not connect to PC? Do this mean this ...

Hi John,

The PCIe DMA application that comes bundled with the kit / reference design has few tests that show the BW or speed of the PCIe transfers. You can run this reference design to get to know the design. Then you could write your own device driver and application and check ( this would be easier o Linux since the source code maybe available). Intel (Altera) may not provide the source code for Windows based device drivers.

If you're using the PCIe dev kit, then depending on the board, there may be reference designs or design examples that show various PCIe link speeds like x1 , x2, x4. You can use each of these to get a feel of how fast the PCIe design/link is working at.
