I am trying to regenerate the sample RAMtest.
During build, the Xilinx ISE tool reports back that several ok modules can not be implemented as they contain tri-states. Here is a sample of the error log.

ERROR:MapLib:824 - Tri-state buffers are not supported in Virtex5. Block ok2
must be removed from the design.
WARNING:MapLib:35 - Mapper failed to process logical block ep00/ok2. Please
refer to previous error/warning message(s) to identify the problem.

I have tried:
instanciating: okHostInterface_xem5010 in place of okHostInterface in the ramtest.v file.
It seems as if the okLibrary.v file need to be updated or modified to deal with the Virtex5 constraint.
Any thoughts?
