After installing 9.1i IP Update 3 for CORE Generator, the taxonomy list shows the following core versions for PCI:
PCI 32-bit Interface v3.161
PCI-X/PCI UCF Generator v2.1
This is illustrated below circled in red:
Xilinx recently changed the names of its PCI core products.
The newest version of the "PCI 32-bit interface v3.161" is "LogiCORE 32-bit Initiator/Target for PCI v3.162" and the newest version of the "PCI-X/PCI UCF Generator v2.1" is "LogiCORE UCF Generator for PCI/PCI-X v2.3". Users should use these new versions of the cores. The next release of CORE Generator will hide the older versions when the user has "Latest Versions" selected in the "Show" drop-down menu.
To target older versions of the core, the user needs to select "All Versions" or "All Version incl. Obsolete".
