2. log in as "anonymous".  Use your email address as your password.
3. You should see a README file, and University, applications, and
   appnote directories, among others.
4. Select the "documentation" subdirectory (or type "cd documentation" if you
   are using text-based ftp)

5. Select the "xactstep6" subdirectory

6. to obtain the archive containing both the Xilinx FPGA and CPLD XNF Specs,
select this file:  xnfspecs_61.tar.Z and copy it over.

   If you are using text-based ftp, use the "get" command.


To extract the archive, type the following:

	- uncompress  xnfspecs_61.tar.Z
	- tar xvf xnfspecs_61.tar


To download the archive using Netscape Navigator:

   Type in this path in Netscape Navigator's URL window:

   ftp://ftp.xilinx.com/pub/documentation/xactstep6/xnfspecs_61.tar.Z


Netscape will issue the message,

   "Warning: unrecognized encoding: x-compress".

Just click "Ok" and select "Save File".  Navigate to the
location you want the file to be saved at, then click on "Save" to copy
the archive over.

NOTE:  When using Netscape, you must download the binary
.Z file rather than the .uu version of the archive.



The extracted files will be:

	      xnf61_7k.ps (XNF XC7000 Specification supplement).

Both are Postscript format files that you can print for viewing.
