Part 3.11: JTAG debug port
A JTAG interface is reserved JTAG interface one the AV7K325 FPGA
development board for downloading FPGA programs or firmware to FLASH. In
order to prevent damage to the FPGA chip caused by hot plugging, a protection
diode is added to the JTAG signal to ensure that the voltage of the signal is
within the range accepted by the FPGA to avoid damage of the FPGA chip.

Part 3.12: Power Supply
The power input voltage of the AV7K325 FPGA development board is
DC12V, and the FPGA development board can be powered by the PCIE slot or
an ex12V power supply. On the carrier board, the voltage is converted
into +5V, +1.2V, +3.3V and 1.8V four-way power supply through 1 way DC/DC
