AR# 33648 ISE Design Suite 11 DSP Tools (System Generator for DSP and AccelDSP Synthesis Tool) Update 4 (11.4/11.5) - README

This Answer Record contains the Release Notes and Known Issues for System Generator for DSP 11.4 and 11.5.

For System Generator for DSP Release Notes from other versions, see (Xilinx Answer 29595).

This README Answer Record contains installation instructions and a list of the issues fixed in the System Generator for DSP 11.4 Update. A successful installation of ISE Design Suite 11.4 changes your design tools version number to 11.4 (verify by running xlVersion at the MATLAB prompt).

Installation Instructions:

  1. Download "Xilinx_11.4_ISE_DS_<platform>.tar" from:
    http://license.xilinx.com/getLicense?group=esd_oms&tab=DownloadUpdates
  2. Untar the archive. For more information about tar files, see (Xilinx Answer 32818).
  3. Open the untarred archive and run "xsetup(.exe)".
  4. Select the root location of ISE Design Suite as your destination directory (that is, C:\Xilinx\11.1 or /opt/Xilinx/11.1).

NOTE: XilinxUpdate run from your ISE Design Suite can also be used to download and install updates. Please see the Help System for more information on running XilinxUpdate.

For more information on other products that are included in this update, see (Xilinx Answer 33216).
