9 Built-In Self Test
The Basys 2 board comes preloaded with a simple self test/demonstration project stored in its ROM. The demo
project (available at the website) shows how the Xilinx CAD tools connect FPGA signals to Basys 2 circuits. Since the
project is stored in ROM, it can also be used to check board functions. To run the demo, set the ROM/USB jumper
(JP3) to ROM and apply power to the board; the seven-segment display will show counting digits, the switches will
turn on individual LEDs, the buttons will turn off individual digits on the seven segment display, and a test pattern
is driven on the VGA port.
