2.7 LED Light

There are 3 red LED lights on the AC7Z035B FPGA core board, one of which is
the power indicator light (PWR), one is the configuration LED light (DONE), and one
is the user LED light. When the core board is powered, the power indicator will light
up; when the FPGA is configured, the configuration LED will light up. The user LED
light is connected to the IO of the PL. Users can control the light on and off by the
program. When the IO voltage connected to the user LED is high, the user LED will
off. When the IO voltage is low, the user LED will light up. The schematic diagram of
the LED light hardware connection is shown in Figure 2-7-1:

2.8 Reset Circuit

There is a reset circuit on the AC7Z035B core board. The reset input signal is
connected to the reset key on the carrier board. The reset output is connected to the
PS reset pin of the ZYNQ chip. Users can use the key on the carrier board to reset
the ZYNQ system. The schematic diagram of the reset connection is shown in Figure
