Description

Solution

Take the following piece of code as an example:

module top(data, out);

        output out

            input [3:0] data;

            input [7:0] data;

        assign out = data[0];

endmodule

Going forward, similar to  prior versions of the XST new parser, the 13.3 version of XST will continue providing the following error message for the above piece of code:

"ERROR:HDLCompiler:711 - "test_711.v" Line 11: Found more than one declaration of port <data>"

In  the above example, there are two input ports with the same port name, which causes the compiler to error out with the ERROR:HDLCompiler:711 error message. 

You can change the severity of this error message to warning by using the switch:
-change_error_to_warning "HDLCompiler:711"
