9.xi XST - "ERROR:Xst:2544 - Unsupported item in port list for module"


When I run XST, I get the following error message. Why?

"ERROR:Xst:2544 - Unsupported item in port list for module."


XST does not accept bus bounds in Verilog module declaration.

For example, this error occurs when the code is written as shown below

module example (clk, datain[3:0], rst, dataout[3:0]);

input clk;

input [3:0] datain;

input rst;

output [3:0] dataout;

This issue is fixed in ISE 9.1i.
