VHDL code or AHDL verilog or bdf are translated into sof/pof files to program the device (on Quartus software) .The configuration data is transferred from the
host computer (which runs the Quartus II software) to the board by means of a cable that connects a USB port on the host computer to the leftmost USB connector on the board. To use this connection, it is necessary to have the USB-Blaster driver installed. Or look for
Altera’s DE2 Board for information about installing the driver. Before using the board, make sure that the USB cable is properly connected and turn on the power supply switch on the board.
Thetre two possible ways of programming In the JTAG mode and Active Serial (AS) mode.
