     10== Reference Design Structure ==

    12 '''Requirements''':
    13 
    14  * Two SISO or MIMO WARP nodes
    15  * Two PCs with Ethernet interfaces
    16  * OFDM Reference Design programming file or XPS project
    17 
    18 == WARP Hardware Setup ==
    19 You will need two WARP nodes to test this reference design. Each node should have an antenna connected to the radio in daughtercard slot !#2. Each node's Ethernet port should be connected to a PC, either directly or via a switch. The two WARP nodes should '''not''' be connected to the same Ethernet switch.
    20 
    21 The two nodes will be programmed by the same bit file, but they must be uniquely identified to allow the wireless MAC layer to properly address each node. The FPGA board's DIP switch is used to identify each node. One board should have its DIP switch set to all zeros (0000); the other should be set to 0001. See the figure below for the proper settings.
    22 
    23 [[Image(OFDMReferenceDesign/Files:setup_05a.jpg)]]
    24 
    25 When you download the reference design to a WARP node, the FPGA board's seven-segment dipslay will show the node's ID, either 0 or 1.
    26 
    27 == Computer Setup ==
    28 The WARP wired-wireless bridge allows the PC connected to a WARP node to communicate with the other PC as if they were connected directly via Ethernet. In order to communicate something useful, the two PCs must have their IP addresses configured manually. We suggest the following IP settings:
    29 
    30  * PC 1 IP Address: 10.0.0.1
    31  * PC 2 IP Address: 10.0.0.2
    32  * Subnet mask (both PCs): 255.255.255.0
    33 
    34 Technically, any pair of IP addresses in the same subnet will work.
    35 
    36 == Running the Reference Design ==
    37 If you want to test the design as-is, use the file '/implementation/download.bit' from the ZIP file.
    38 
    39 Configure both WARP nodes using the refence design bitstream. You can download the bitstream directly via iMPACT using the FPGA board's built-in USB JTAG programming circuit, an external JTAG cable or using just a CompactFlash card.
    40 
    41 Once both WARP nodes are configured, you should be able to ping each PC from the other. You can then run any IP-based networking application between the PCs. We suggest using VLC to stream video from one PC to the other. We have written a [wiki:VLCStreaming brief tutorial] on setting up VLC. You can see this exact demo running in our [http://youtube.com/profile_videos?user=ricewarp demo videos].
    42 
    43 == Reference Design Files == #refDesignFiles
    44 The full OFDM Reference Design is available for download. The ZIP file below contains the full XPS project for the OFDM reference design, including both the hardware and software designs.
    45 
    46  * [http://warp.rice.edu/bigFiles/OFDM_ReferenceDesign_v12_1.zip OFDM Reference Design v12.1] (65MB .zip file)
    47 
    48 This design integrates the various hardware, PHY and MAC cores and code we have built. The individual cores and source files are also available in the [source:/ WARP repository].
