Altera DE4 PCIe example tutorial design doesn't detect by lspci command

[Altera_Forum]

I'm a graduate student of University of Moratuwa, Sri Lanka. Recently we bought an Altera DE4 board from terrasic. I have connected the DE4 board to a PC having linux version 3.13.0 and built up the PCIe design example given by the altera using Quartus II 13.1. After programming the board with the generated "de4_pcie_tutorial.sof" file, I have rebooted the PC. But still the "lspci" command does not recognize the board.  

Could you please advise me on this whether there is any special issue to be considered or not? Thank you very much for your help in advance.  thanks & regards, Kavinga Upul

Is DE4 Stratix IV or Stratix V...? Did you look on the Altera wiki or at Terasic for the sample designs and driver?

You should check LTSSM state with Signal Tap.  

 Also, there is a whole chapter dedicated to debugging in PCIe User Guide.
