As you corrected the sine wave display, the LEDs might not have lit up in sequence as you pressed the Sine Wave Sequencer button. With each push of the button, there should be a single, cycle-wide pulse on the GPIO_BUTTONS_re[1] signal. If there is more than one, the behavior of the LEDs becomes irregular. In this section of the tutorial, use Vivado logic analyzer to probe the sine wave sequencer state machine, and to view and repair the root cause of the problem.

Before starting the actual debug process, it is important to understand more about the sine wave sequencer state machine.
