Recommended Design Experience
The LogiCORE PCI-X Interface is pre-implemented allow-
ing engineering focus on the unique user application func-
tions
of
a
PCI-X
design.
high-performance design that is challenging to implement in
any technology. Therefore, previous experience with build-
ing high-performance, pipelined FPGA designs using Xilinx
implementation software, constraint files, and guide files is
recommended. The challenge to implement a complete
PCI-X design including user application functions varies
depending on configuration and functionality of your appli-
cation. Contact your local Xilinx representative for a closer
review and estimation for your specific requirements.
Regardless,
PCI-X

Timing Specifications
The maximum speed at which your user design is capable
of running can be affected by the size and quality of the
design. The following tables show the key timing parame-
ters for the LogiCORE PCI-X Interface. Timing Parameters
in the 66MHz PCI-x are listed in
Table 4
. Timing Parameters
in the 33MHz PCI are listed in
Table 5
.
