You would still need a PCI core although you can get those a lot cheaper than

I don't think you need anything PCI with the specified PLX chip.

The PEX8311 has a description of:

   "8/16/32-bit, 66MHz, Local Bus to PCI Express Bridge"

As far as I am aware there are no PCIe equivalents to the PLX 9054 (for
example) - ie PCIe to local bus bridges.

I believe that is an equivalent, but still relatively expensive in
comparison to just a PHY chip.

You might need some information about laying out your board for PCIe
compliance however you can probably glean that information from a PLX example
design :)

Very true - they seem to have the board layout all right there from
their reference design development board.  Pretty nice!
