    v33 v34  
    8989We have created an [wiki:HardwareUsersGuides/FPGABoard_v2.2/MGTs/SFP-Ethernet example design] that uses the SFP Ethernet in a cabled loopback setup.

     91Every user design for the Virtex-4 must instantiate the MGTs or their performance will degrade over time (Xilinx app notes [http://www.xilinx.com/support/documentation/application_notes/xapp732.pdf here] and [http://www.xilinx.com/support/answers/23410.htm here]). In order to make this easier we have created a pcore ([source:PlatformSupport/CustomPeripherals/pcores/mgt_null_controller_v1_01_a available in the repository]) that connects to all the MGT tiles and keeps them powered on. If you would like to use one of the MGTs you can use this as a model for connecting and disconnecting the appropriate MGT. An example MHS and UCF that uses the core is available [source:ResearchApps/PHY/WARPLAB/WARPLab_v05_2/EDK_Files_MIMO_4x4_FPGAv2 here].
