This README contains the Release Notes for the 5.1i Service Pack 3. The Release Notes include installation instructions and a list of the issues that are fixed by this Service Pack.


A successful installation of Xilinx ISE 5.1i Service Pack 3 will update your software version number to 5.1.03i.

NOTE 1: The destination directory specified during the set-up operation must contain an existing Xilinx ISE 5.1i installation. Only existing files are updated. Any new device support not previously installed should first be installed from the Xilinx ISE 5.1i CD before adding Service Pack 3.

NOTE 2: The Xilinx ISE 5.1i environment variable should be set before commencing the installation of Service Pack 3.

Download installation instructions for PC:
1. Download 5_1_03i_pc.exe from:
2. Run "5_1_03i_pc.exe".

Download installation instructions for Solaris Workstation:
1. Download 5_1_03i_sol.tar.gz from:
2. Untar the downloaded file into an empty "staging" directory.

For example:
cd /home/staging_dir
gzip -d 5_1_03i_sol.tar.gz
tar xvf 5_1_03i_sol.tar

3. Run "5_1_03i_sol/setup".
