Because the power supply of the ZYNQ FPGA has the power-on
sequence requirements, in the circuit design, we have designed according to
the power requirements of the chip. The power-on sequence is
+1.0V->+1.8V->(+1.5 V, +3.3V, VCCIO) circuit design to ensure the normal
operation of the chip.
Part 20: Fan
Because ZYNQ035 generates a lot of heat when it works normally, we add
a heat sink and fan to the chip on the board to prevent the chip from
overheating. The control of the fan is controlled by the ZYNQ chip. The control
pin is connected to the IO of the BANK34. If the IO level output is low, the
MOSFET is turned on and the fan is working. If the IO level output is high, the
fan stops. The fan design on the board is shown in Figure 20-1.

The fan has been screwed to the AX7350B FPGA development board
before leaving the factory. The power of the fan is connected to the socket of
