Demonstration Setup

To set up the demonstration, perform the following steps:

1. Connect a PS/2 keyboard to the development board.

2. Connect the VGA output of the development board to a VGA

monitor (both LCD and CRT type of monitors should work)

3. Connect a speaker to the Line Out port of the development board.

4. Load the bit stream into FPGA.

5. Ensure that all the switches, SW[9:0], are set to 0 (Down Position).

6. Press KEY1 on the development board to start the music demo.

7. Press KEY0 on the development board to reset the circuit.

Table 6–1 illustrates the usage of the switches and push buttons (KEYs).
