Getting the Latest Software and Documentation Updates
You can use the ISE® XilinxUpdate utility to compare the installed version of your software and documentation with updates available on the Xilinx® website. If updates are available, you can download the updates and update your installation. You must have write permission in the installation area to install updates.
Note Alternatively, you can select Help > Xilinx on the Web > Download Center to go to the Download page of the Xilinx website, which allows you to download Xilinx products, software updates and service packs, and device models.
