Problem Title:
EZtag: "Input passed end of file" message when programming 9572 CPLD


Problem Description:
Keywords: 9572, eztag, eof, end of file

Urgency: standard

General Description:

The fitter seems to complete successfully but when the the
<design>.jed file is loaded into EZTAG a message appears saying
that the Input is passed end of file.


Solution 1:

On examination, the user will most likely find that the file
length of the <design>.jed file is zero.  This is because the
9572 was not supported with the early versions of XACT-CPLD and
XABEL-CPLD.  The fitter reports that the device is not
supported in the fe.log file and a 0 length JED file is
created.

To upgrade to a later version of the software that supports the
9572, getget following two update patches from the Xilinx web
or ftp site:

For a PC :

ftp://ftp.xilinx.com/pub/swhelp/cpld/eztag_pc.zip
ftp://ftp.xilinx.com/pub/swhelp/cpld/fitterpc.zip

For a Sun workstation :

For a HP workstation :
