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 ...

DMA will not be connected to PC. The design flow is

PC <-> PCIe link <-> FPGA <-> PCie with DMA IP <-> PCIe EP Application

The DMA IP is meant for the PCIe application to communicate faster with the PCIe EP core in the FPGA. Download the example design, compile and program the FPGA on the kit, either insert the kit into PCIe slot in PC, power up , install linux drivers / windows drivers and start the PCIe application which will run the DMA tests..
