AR# 4770

A1.5/F1.5 CPLD - Signature/User Code always generates "sign" when not using default option.

Description

Keywords: F1.5, Foundation, Signature, sign, CPLD, programming

Urgency: Standard

General Description:
When you specify a Signature under the Programming tab in the
Implementation options dialog, you get this message:

hprep6 -i fe_temp -r jed -a -l christes.log -n signature_str

Programming File Generator: version M1.5.19
(c) Copyright 1989-1997 Xilinx Inc. All rights reserved.
Signature length is limited to 4 characters, using 'sign'.

Solution

1

The workaround is to leave the default "Use <design name>" option and change the actual name of the project. The signature will then be the first 4 characters of the project name.

This is a software error which has been fixed in the latest 1.5 service pack
currently available on our website.

Another workaround:
* Run the flow engine all the way through
* Go back one step
* Use the command line:
hprep6 -i fe_temp -r jed -a -l logfile.log -n test

This will use the 4 characters: test as your signature.
