| - | **Exercise 2 Pass-off:** Show a TA your circuit and have them check that it will not damage the board. Do not turn on the NEXYS 4 board until you have reviewed your circuit with a TA. It is relatively easy to damage the logic chips or the FPGA board if you hook up your logic circuit incorrectly. \\ \\ | + | **Exercise 2 Pass-off:** Show a TA your circuit and have them check that it will not damage the board.

| At this point, the FPGA board should provide the button inputs to your circuit and the LEDs will display the logic produced by your circuit. Test all input combinations to make sure your two functions (F and A) are producing the correct results. | At this point, the FPGA board should provide the button inputs to your circuit and the LEDs will display the logic produced by your circuit.
