2. While not required, we recommend that you install the latest 3.3i Xilinx Software Service Pack.
3. This IP Update is available as a .zip file or as a "gzip" compressed .tar file. On Windows, the Zip file can be unpacked using WinZip 7.0 SR-1 or later. On UNIX, some versions of UnZip may be used to unpack this Zip file, but certain known issues with this exist, as described in (Xilinx Answer 7711). For UNIX platforms, we recommend that you download the ".tar.gz" file and unpack it using the UNIX command line utilities "gunzip" and "tar" (not GNU tar). Note that the date stamp of the "/user/sbin/tar" command you use must be February 10, 1998 or later. This version of "tar" is usually supplied with Solaris operating system versions 2.6 or later. WinZip and GNU "tar" are not recommended for extracting the ".tar.gz" archive due to differences in the way they handle files with long path names. Please see (Xilinx Answer 11162) for more details.
4. Close the CORE Generator application if it is running. Download the Zip file or tar.gz and save it to a temporary directory.
5. Extract the Zip file or tar.gz archive to your Xilinx installation directory.
6. Delete the corelib.xml file located in /coregen/ip. This will force CORE Generator to regenerate this database during startup.
7. Restart CORE Generator. CORE Generator will automatically detect that new IP has been added and will give you an opportunity to update "All" cores to the latest versions, add only "New" cores, or make only a "Custom" selection of cores available for your current CORE Generator project.
8. Determine whether the installation has succeeded by verifying that the new cores are visible in the CORE Generator GUI, such as "LFSR" in the "DSP/Building Blocks" folder.
