Meeting PCI timing with PCI Bridge

I am trying to specify the 28 ns toff (active drive to float time) for a Xilinx Spartan 3. The Xilinx documentation is off no help and following the example for the Xilinx PCI core results in errors.

Does anybody have an example of a UCF file which can correctly constraint all timing for the Opencores PCI Bridge.

Note that I have constrained successfully the tco, tsu and th.

Many thanks
