I have tried your example and it's work fine....:-))
Thanks,

Hello Edigio,
I've had to do this type of thing to make use of a GCLK input as a
general I/O in EDK (otherwise you have to leave EDK and stuff in a
bufg). For examples, you can look in the
$EDK_INSTALL_DIR\hw\XilinxProcessorIPLib\pcores\util_bus_split_v1_00_a
for a Xilinx provided example and I am attaching a simple blinker
example that doesn't even connect to any of the microblaze stuff. Both
of these show how to instantiate general logic in EDK that may or may
not be related to the microblaze system. For the blinker, put it into
your global user cores directory or your project pcores and you can then
add it in the add edit cores dialog.
Any other discussion about how to do this should be moved to a Xilinx
forum as it has wandered off topic for this list.

|You can look in one of John's older mbvanilla releases for the
|"my_inverter" which shows how to instantiate generic logic.
|So long as you describe the block correctly with the mpd/pao
|files as John mentioned, you can instantiated any generic
|logic. Even if it's not related to an embedded processor.

|I've put lot's of stuff into designs that had nothing to do
|with the microblaze and this is a convenient way to go. The
|constructs used in making EDK compatible
| components also serve to encourage fairly generic,
|parameterizable blocks. And it's a lot better than jumping
|back and forth between xps and ise.
