Urgency: Standard

General Description:
This Answer Record contains Release Notes for ISE 7.1i IP Update 2 (also known as IP2_H) and includes the following:

- Software and Tool Requirements
- Installation Instructions
- MXE Simulation Library
- Updated IP List
- Known Issues

Notice : We have identified an issue with ISE 7.1i IP Update #2 that causes problems when a core is generated from inside Project Navigator instead of the standalone version of COREGen.

To work around the problem, COREGen must be run as a standalone to generate a core. The core can then be added to the Project Navigator project using "Add Source" or "Add Copy of Source" and selecting the XCO file representing the core just generated. See (Xilinx Answer 21954) for further details.

This Coregen / Project Navigator integration problem has been fixed in ISE 7.1i IP Update 3.

We would also recommend that you do not install this update unless you specifically need the features included in this update.

What's New

New or modified cores in this release are:
- PCI UCF Generator v1.0
- Binary Counter v8.0
- Reed Solomon Encoder v5.0
- Floating Point Operator v1.0

Cores Included in this Release
http://www.xilinx.com/ipcenter/coregen/coregen_iplist_71i_ip2.htm


b>What's New in the CORE Generator application

- New C++-based IP customization GUIs are available for most new core versions in this release load and display faster on your desktop.
- CORE Generator now passes device-specific data to the customization GUIs instead of just the device architecture family. This enables CORE Generator to optimize the generated core for the specific device and also prevents you from trying to generate a core that would be too large for a particular device.

Install the IP Update using one of the following methods:

Method 1: Automated Update using the Updates Installer

1. Start the CORE Generator Update Installer (from the CORE Generator Main GUI, select Tools -> Update Installer).
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 7.1i IP Update 2 (FTP)," or " ISE 7.1i IP Update 2 (HTTP)" from the list of updates in the Available Packages panel, depending on which mechanism works better for you.
3. Click "Add To Install Queue" to add the zip file for the update to the install queue.
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 software Service Packs.
4. Click "Install All Packages From Queue" to automatically initiate a download of the update.
After the update is downloaded, the Updates 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; you can then restart CORE Generator.
5. To confirm that you have installed the update properly, check the following file:
C:\Xilinx\coregen\install\install_history

NOTE: This step assumes that your Xilinx design tools is installed in C:\Xilinx.

Method 2: Manual Installation Method

1. Close the CORE Generator application, if it is running.
2. Download the ".zip" file (PC) or "tar.gz" file (UNIX) from the following location and save it to a temporary directory:
http://www.xilinx.com/xlnx/xil_sw_updates_home.jsp?update=ip&software=7.1i

NOTE: Before you can access this page and the files listed on it, you must be registered for CORE Generator IP Updates access.

3. Extract the ".zip" file (71i_ip_update2.zip) or "tar.gz" (71i_ip_update2.tar.gz) archive to the root directory of your Xilinx design tools installation. Allow your extractor utility to overwrite all existing files and maintain the directory structure pre-defined in the archive.

PC
Unzip the ".zip" file using WinZip 7.0 SR-1 or later.
The Xilinx design tools installation directory is typically located at "C:\XILINX" if the installation defaults were used. You can verify the location of the Xilinx install by entering the following on the DOS command line:
echo %XILINX%

UNIX
Use UnZip to unpack the ".zip" file. Xilinx recommends that you download the "tar.gz" file and unpack it using the UNIX command line gunzip and tar utilities. WinZip and GNU tar are not recommended for extracting the "tar.gz" archive because of differences in the way they handle files with long path names. See (Xilinx Answer 11162) for more details.

If you have already installed your Xilinx ISE design tools, the Xilinx installation directory location is the value of the XILINX variable (defined by your setup script). After sourcing your Xilinx setup script, enter the following to determine the location of your Xilinx installation:
echo $XILINX

You might need system administrator privileges to install the update.

4. Restart CORE Generator. During start-up, CORE Generator automatically detects that new IP has been added to your installation. It allows you to specify which IP customizers (cores) will be visible in your currently active CORE Generator project. For your current project, you can select the following:
- Display only the latest versions for "All" cores in the catalog.
- Update the catalog view to add only "New" cores to the display.
- Make a "Custom" selection of cores visible in the CORE Generator catalog display for your current project.

5. Determine whether the installation was 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 pre-compiled MXE libraries, see (Xilinx Answer 10616).
