RS-232 Based Communication with Xilinx FPGAs

Design Files

17th March 1993

This file contains the information used to create the application note
"RS-232 Based Communication with Xilinx FPGAs". The information is
supplied in compressed form and will have to be uncompressed before you
can use it. The program to uncompress these files is called PKUNZIP and
has been supplied on the disk. It is strongly suggested that you create
a new directory on your hard-disk and use this to contain all of the
expanded files. Note that expanding some of these archives will result
in a set of sub-directories that are used by the WORKVIEW CAD package.

In general, to uncompress the file use:-

<path to disk>\PKUNZIP -d <path to archive>\<archive name> <path to directory>

There follows a description of the contents of the various archives supplied
on this disk...


Archive name:  PRINT_PS.ZIP
=============

Contains all the files required to print the UART application note - in
PostScript format. Print each of these files to a PostScript compatible
printer to produce the whole document.
