16 years agoHere's a few things to check:
1. What kind of a quartus license do you have? Is you .sof file time limited? If so, everytime you power off and then on the board, the previous programming will be cleared, and it will run the startup sequence. Make sure you use the Quartus programmer again every time you turn on the board. 2. Have you added the correct pin assignments? Have you correctly hooked up the reset key and the clock in your top level module?
