Hi Chenwei, I'll fix the verilog anyway to get rid of that erro, but I think you'll find that if you use 14.7 the error will go away. In any case, 14.7 is the last version of ISE that Xilinx will release, so it's the one we're going to target in our libraries - it might be a good idea to upgrade your toolflow for this reason alone.
