waveforms can be displayed through the mixed signal header. In addition, one PWM RC circuit source is
routed to the AV input pin of an analog quad. This AV pin can be used to monitor the generated voltage
with high accuracy, depending on the ADC resolution configured in the FPGA.

Push-Button System Reset
A push-button system reset switch with a schmitt trigger is provided on the board, as shown in the
following figure. The Schmitt trigger reduces noise on the system reset push-button. The SmartFusion
MSS reset is synchronized with this reset.
