It can be seen that "sysgenPolyphaseChannelizer.mdl" does not use the latest versions of IP blocks available within System Generator 14.x.
Will this be updated in ISE System Generator or Vivado System Generator?
This will not be updated in ISE System Generator as there is no plan to remove the versions of IP blocks being used at this time, and as such the demo will remain valid. The IP can be updated if required by the user.
This example has already been removed from the Vivado System Generator examples.
