PCI Express board is not detected by lspci in linux

I have Cyclone IV GX FPGA Development Kit Board. I have made the time limited .sof file in Quartus. I have used a reference design for cyclone IV. 

(PCI Express to External Memory Reference Design:c4gx_pcie_qsys_msgdma_11_0_1.) 

 

In Quartus programmer I Sucessfully download the .sof file to fpga. The status LED (alive LED starts blinking). But when I want to see this board in linux, there is no board detected. Why? Any suggestions?
