Xilinx 8.1 & Xilinx 14.7 Version will not compile my design

Hi.

I designed the processor DorQ which is attached. It compiles fine in Quartus 2 but my business partners use Xilinx 8.1 & Xilinx 14.7 Version and on these software, it shows errors which are also attached to this thread.
Could someone please provide a solution to this problem. Is there a setting we can change on Xilinx 8.1 & Xilinx 14.7 Version that will do away with the error messages.
Thanks for your reply.

There are no internal tristate buffers in the newer Xilinx devices.  You could try to target a Spartan II part instead and see if it can pass synthesis, however the real solution would be to redesign the logic so that the ports are not all bidirectional.
