Stratix V Pci Express gen II x2 reference design

[FPaol1]

Hi, i don't found this reference design (i only find x4 and x8)

I tried to modify the x4 design but it gives me error s listed below.

I modified in qsys:

-Number of lanes x2 in the DUT instance

-Application interface Avalon-ST 64-bit in the DUT instance

-Lanes x2 in the APPS instance

-Application interface Avalon-ST 64-bit in the APPS instance

-Number of reconfiguration interfaces 3 in the PCIe Reconfig Driver Intel FPGA IP

-Number of reconfiguration interfaces 3 in the Transceiver Reconfiguration Controller Intel FPGA IP

-I deleted the lanes in the top level file

Please help me

Hi, I believe this is because the Quartus was referring to an incorrect file. If you are using an older version of design, but use it in a newer Quartus version, please try to remove the **.qip file from the project and add the newly generated ***.qsys file instead. Regards -SK
