8.1i Install - ISE Service Pack Release Notes (README)


This README Answer Record contains the Release Notes for 8.1i Service Packs. The Release Notes include installation instructions and a list of the issues that are fixed.

NOTE: ISE Service Packs are cumulative; consequently, fixes found in Service Pack 1 are also found in Service Packs 2 and 3.

A successful installation of Xilinx ISE 8.1i Service Pack "x" updates your software version number to 8.1.0xi.


- The destination directory specified during the setup operation must contain an existing Xilinx ISE installation. Only existing files are updated. Any new device support not previously installed should first be installed from the Xilinx ISE CD before adding the Service Pack.

- You must set the XILINX environment variable before installing the Service Pack.

Installation Instructions for Windows Users

1. Download "8_1_0xi_win.exe" from:

2. Run "8_1_0xi_win.exe."

Installation Instructions for Red Hat Linux and Sun Solaris Users

1. Download "8_1_0xi_<platform>.zip from:

2. Move the zip file to an empty "staging" area, and unzip the downloaded file.

For example:

mv 8_1_0xi_<platform>.zip /home/<staging_dir>

cd /home/<staging_dir>

unzip 8_1_0xi_<platform>.zip

3. Run "setup."

NOTE: WebUpdate can also be used to download the Service Pack update on Linux and Windows platforms.
