 '''FPGA Board Version Notes''' [[BR]]
 The OFDM Reference Design uses very similar hardware designs for the two versions of the WARP FPGA Board (v1 and v2). The primary difference is the use of a soft Ethernet MAC in the Virtex-II Pro FPGA and hard TEMAC in the Virtex-4. The custom WARP peripherals (OFDM transceiver, AGC, timer, radio controller, etc.) are identical in both projects.
 
 The software projects are also very similar across boards. The same source files are used for both versions. A few {{{#ifdef}}} statements are used in WARPMAC to include/exclude board-specific code at compile time. The primary difference is support for user I/O. The project for the FPGA Board v1 uses an xps_gpio core as an interface to the LEDs, hex displays, buttons and switches. The FPGA Board v2 project uses the custom [wiki:HardwareUsersGuides/FPGABoard_v2.2/UserIO/warp_v4_userio warp_v4_userio] core and driver for the user I/O. WARPMAC provides a single API for user I/O, so MAC-level code can be fully portable between FPGA Board versions.
