Part 2.6: LED Light on Core Board
There are 3 red LED lights on the AC7100B 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 illuminate; when the FPGA is configured, the configuration
LED will illuminate. The user LED light is connected to the IO of the BANK34,
the user can control the light on and off by the program. When the IO voltage
connected to the user LED is high, the user LED is off. When the connection IO
voltage is low, the user LED will be lit. The schematic diagram of the LED light
hardware connection is shown in Figure 2-6-1:

Part 2.7: Reset key
There is a reset key on the AC7100B FPGA core board. The reset key is
connected to the normal IO of the BANK34 of the FPGA chip. The user can use
this reset key to initialize the FPGA program. When the key is pressed in the
design, the signal voltage input to IO is low, and the reset signal is valid; when
the key is not pressed, the signal input to IO is high. The schematic diagram of
