Basys3™ FPGA Board Reference Manual
10 Built-In Self-Test
A demonstration configuration is loaded into the SPI Flash device on the Basys3 board during manufacturing. The
source code and prebuilt bitstream for this design are available for download from the Digilent website. If the
demo configuration is present in the SPI Flash device and the Basys3 board is powered on in SPI mode, the demo
project will allow basic hardware verification. Here is an overview of how this demo drives the different onboard
components:
• The user LEDs are illuminated when the corresponding user switch is placed in the on position.
• The VGA port displays feedback from a USB Mouse.
• Connecting a mouse to the USB-HID Mouse port will allow the pointer on the VGA display to be
controlled.
• On power-up, each digit of the seven-segment display will display a counter output from 0-9 that
increments once a second.
• Pressing BTNU, BTNL, BTNR, or BTND will cause a digit of the seven-segment display to go blank.
• Pressing BTNC will reset the design.
• On power-up, a welcome message is sent over the UART. Also, every time a button is pressed a message
is sent. The UART can be connected to using a terminal program with 9600 Baud, 8 data bits, 1 stop bit,
and no parity.
All Basys3 boards are 100% tested during the manufacturing process. If any device on the Basys3 board fails
test or is not responding properly, it is likely that damage occurred during transport or during use. Typical
damage includes stressed solder joints and contaminants in switches and buttons resulting in intermittent
failures. Stressed solder joints can be repaired by reheating and reflowing solder and contaminants can be
cleaned with off-the-shelf electronics cleaning products. If a board fails test within the warranty period, it will
be replaced at no cost. Contact Digilent for more details.
