Hardware and Software

The Spartan 3 FPGA Development board from Digilent is used for the project.An additional circuit board with R2R ladder network is built to get 16bit VGA display.ModelSim is used for RTL simulation. Xilinx ISE is used for synthesis. The impact tool that comes with Xilinx ISE is used for downloading the bit stream into the Spartan3 FPGA.

Error: Reference source not found.shows the Spartan 3 FPGA board. A few specific parts of the board that are of interest to us include dedicated VGA port, three 40-pin expansion ports,four seven segment LED displays, eight slide switches, four momentary-contact push button switches and eight LEDs. There is an on-board voltage regulation to provide 3v, 2.5v and 1.2v. The board contains 1MB of Fast Asynchronous SRAM(10 ns SRAMs in two 256K*16 configuration) and 50 MHz oscillator on the back of the board
