(Xilinx Answer 24854) - 9.1i CORE Generator - The Tools -> Software Updates selection is grayed. How do you select Software Updates in CORE Generator?

Platform Support

- Windows 2000 Professional (Service Pack 2 to 4)

- Windows XP Home (Service Pack 1)/Professional (Service Pack 1)

- Sun Solaris 8/9

- Linux Red Hat Enterprise 3.0 (32-bit and 64-bit)


You might need system administrator privileges to install the update.

First, ensure that 9.1i SP2 or later is installed. Xilinx ISE design tool updates are available from the Download Center at:


Install the IP Update by following one of the two methods listed below:

Method 1: Automated Update using the Web Installer

1. Start the CORE Generator Web Installer (from the CORE Generator main GUI, select Help -> Software Update...). This starts the WebUpdate application. If you are prompted for a proxy host, contact your administrator to determine the proxy host address and port number that you should be using to get through your firewall.

2. Select "ISE 9.1i IP Update 1" from the list of updates in the Available Packages panel.

If you are prompted to enter a login name and password, use the Xilinx login and password that you normally use to download IP Updates and Service Packs.

3. Click OK to initiate a download of the update. After the update is downloaded, the WebUpdate Installer displays a dialog box indicating that it is terminating the CORE Generator session and installing the downloaded archive. Another dialog box will indicate when the update installation is complete; when this appears, you can then restart CORE Generator.

4. To confirm that you have installed the update properly, select Help -> About.

Method 2: Manual Installation

Use this method if you are behind a firewall and do not know your proxy settings:

1. Close the CORE Generator application, if it is running.

2. Download the appropriate ".zip" file from the following location:


Save it to a temporary directory by specifying:

- "ISE IP Update" as the Download Type

- "9.1i" as the ISE Version

- Your desired operating system for the Operating System selection (the same ".zip" file is supplied for all platforms).

3. Extract the ".zip" file (ise_91i_ip_update1_install.zip) archive to a temporary location.

4. In the root level of the unarchived directory structure, run the setup (.exe) executable to install the update.

5. Restart CORE Generator. CORE Generator automatically detects and displays the newly installed IP cores.

6. Determine whether the installation is successful by verifying that the new cores are visible in the CORE Generator GUI.

MXE Simulation Library

The cores delivered with this IP Update require updated XilinxCoreLib libraries. For information on how to obtain the latest precompiled MXE libraries, see (Xilinx Answer 10616).
