problem with connection in .bdf

Hi all,

I found a problem when i try to connect the pin in .bdf file~

This is part of my verilog file

output [24:0] fsa,

wire [25:0] address_to_the_cfi_flash;

assign fsa = address_to_the_cfi_flash[25:1];

My problem is that how can i connect the [25:1] to the pin with [24:0] in a bdf file ?

Thanks!

Jeorge
