MAKEBITS 5.2.1: Problem with xc5200 devices when Makebits -t option is
used.



Problem Description:
KEYWORDS: makebits, -t, tie, xc5200

URGENCY: standard

GENERAL DESCRIPTION:

XC5200 device does not function properly when bitstream is generated with -t
(tie all unused interconnects to known state) makebits option.	One of the
observed problems is that the some of the outputs may be stuck at one state.




Solution 1:

Use a patch called makebits.zip in Xilinx ftp site:

http://www.xilinx.com/support/techsup/ftp/htm_index/sw_xact-pc.htm.

This patch is for Makebits version 5.2.1/6.0.1, and fixes problem when using
makebits with -t option on xc5200 designs.
