PLD on Breadboard Programming WARNING!
When you connect your DE10-Lite PLD PCB to your computer with a USB cable, verify that the 7-segment display shows "3701". If not, use the Quartus archive file, safe_3701.qar, to put your DE10-Lite into a "safe mode." Program this design using the ".pof".

Only program your subsequent labs (or other assignments) using ".sof" files.

When your DE10-Lite is not being used, remove the USB connector from your computer (not from the DE10-Lite). (When not in use, I suggest that you leave your USB connected to your DE10-Lite and your DE10-Lite connected to your breadboard with the ribbon cable.)

When wiring up a new circuit, keep the DE10-Lite and breadboard un-powered. When your circuit wiring is complete, plug in the USB cable to your computer and then program the DE10-Lite using an ".sof" file.
