Problem Title:
Defining pin attributes/locations for a VHDL code using Viewsynthesis


Problem Description:
This describes how some attributes can be added to the IO
pins using Viewsynthesis.


Solution 1:

A DESIGN.FPN file needs to be created in the project directory
with the following commands:

       | a comment
       | Define location TOP-RIGHT for pin RST
       bufatt RST loc=tr
       | Define location p13 and FAST output for pin outt[7]
       bufatt outt[7] loc=p13, fast

   Note that the line:
      bufatt RST loc=tr
      causes the RST pad to be located "tr" (or "top right").

    Note that the line:
      bufatt outt[7] loc=p13,fast
      ends up as attributes on the outt[7] pad -- it is to be
      located at pad p13, and to be a "fast" slew-rate pad.
