Convert bit to bin Xilinx file
Better than convert, it is possible to directly generate the bin file with ISE Project Navigator.
Before double clicking on &quot;Generate Programmng File&quot;, first do secondary button on it and go to: &quot;Process Properties...&quot;
In there, under &quot;General Options&quot; tab check the -g Binary option.

I know there are other ways for converting the .bit file to .bin files directly but I don't know how.
