2.15 System Status Interface

As shown in
sensors to monitor the status of the board, such as FPGA temperature, board power
monitor, and fan speed status. These interfaces are connected to the System MAX10
FPGA on the board. The board management logic (Dashboard) in the System MAX10
FPGA will monitor those status and perform corresponding control according to the
status. For example, when the temperature of the FPGA increases, the system will
automatically increase the fan speed to reduce the temperature. When the
temperature of the FPGA continues to exceed the working range (such as a fan failure
condition), the FPGA power will be cut to protect the board.
The board also provides USB to UART interface to connect with the System MAX10
