Download Rev2 Update

To get the Rev2 update to resolve the issue described above, apply the attached patch at the bottom of this AR to the Xilinx ISE 14.x software installation.

Install the patch by extracting the contents of the ".zip" archive to the root directory of the Xilinx ISE 14.x software installation. Select the option that allows the extractor to overwrite all of the existing files and maintain the directory structure predefined in the archive. After installing the patch, regenerate the LogiCORE IP Tri-Mode Ethernet MAC v4.6 core in the 14.x CORE Generator tool.For further information on finding the Xilinx installation and using environment variables, see (Xilinx Answer 11630).

NOTE: You might need system administrator privileges to install the patch if you do not have write permissions to the Xilinxinstallation directory.
