Hi Oussama,

Thanks for putting the document together.

In the future, please just post a link to the document, so that the
160kB attachment doesn't come through the list.

Also, there's no need to edit all the files to change the relative
include path specified in usrp_std.v:

This is not required:

  `include "/../../../firmware/include/[name].v" will need to be changed to
  `include "c:\usrp\include\[name].v"


You might have to edit the project property that sets the top of the
include path.  Actually I don't think you should even have to do that,
since I know that Matt and I build this code from different
directories and don't change anything.
