Spartan 2 FPGA
The block diagram of the D2XL board shows all
connections between the FPGA and the devices on
the board. All FPGA pin connections are shown in the
following table.
The Spartan device can be configured using the
Xilinx JTAG tools and a parallel cable connecting the
D2XL board and the host computer. Note that a
separate JTAG header that connects directly to the
JTAG pins is also provided.
For further information on the Spartan FPGA, please
see the Xilinx data sheets available at the Xilinx
website (www.xilinx.com).
