Problem Title:
Hardware Debugger 1.5/2.1: Parallel Cable toggles PROG after Download.


Problem Description:
Urgency: Standard

General Description:
When programming an FPGA in Hardware Debugger through the parallel port, the program pin goes low af ter configuration thus erasing the fpga.


Solution 1:

This problem can be fixed by setting the following environment variable:

SET XIL_HWD_PCAB_FIX=1

Environment variables can be set in the autoexec.bat file for Windows 95/98.
The exact line above can be added to the file using the program "sysedit".

In Win NT right-click on the "My Computer" desktop icon, go to Properties,
and select the Environment tab.
The Variable is 'XIL_HWD_PCAB_FIX', Value is '1'.

Reboot the PC.



Solution 2:

Disconnect the parallel cable after configuration. This has worked when the program pin glitches se veral minutes after configuration is completed.
