Built in Self Test
The Basys2 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
Basys2 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.
If the self test is not resident in the Platform Flash ROM, it can be programmed into the FPGA or
reloaded into the ROM using the Adept programming software.
