Core Generator is a "delivery vehicle". The PCI LogiCORE from Xilinx
is a piece of IP, in the form of a netlist. Initially, Xilinx would
deliver the netlist directly to customers on a CD or via download
from a web page. If you have the PCI LogiCORE netlist, it does not
matter if you have Core Generator or not.

Xilinx currently makes the PCI LogiCORE available through Core
Generator, and also available on the web. Web download is only
available if you own a license, you cannot download an eval from
the web... Core Generator is capable of generating an eval copy.
In any case, your issue is that the netlist for XC4000E devices
has been discontinued a long time ago, and is no longer available
or supported. What is currently available on the web and through
Core Generator is a netlist that is suitable for derivatives of
the Virtex family:
* Virtex, Virtex-E, Spartan-II, Spartan-IIE
* Virtex2, Virtex2Pro, Spartan3
* Virtex4
If you are just doing this for fun, you might consider using the
PCI interface from OpenCores. You could target this to any device
you wish. If you are doing "serious development work" you probably
don't want to be using XC4000E but instead one of the devices above
in which case you can use the current PCI LogiCORE.
Hope that helps,
Eric

Thank you, Eric, for quick answer. I have bought some pcs of
XC4013E-PQ240-3C on eBay :) for my unprofit use in my hobby only. But
I don�t understand what is role of PCI LogiCore, when CoreGen of older
Foundations isn�t usable (... if I understand correctly). To generate
correct pci.vhd for appropriate core only? But why aren�t downloadable
pci.vhd-s for this purpose directly (e.g. on xilinx�s ftp)??
