Figure 2.7 USB Power Supply Interface Schematics 

We can see that after the PB8 is turned on, the power supply is connected to 

the VCC5V0 level network of the development board, and then converted to the 

1.0V (FPGA core voltage), 1.8V or 3.3V. Among them, 1.8V and 3.3V are the BANK 

voltage of the FPGA. The two voltages are provided to meet the level standards of 

various external signals. The conversion circuit is shown below.   

 

Figure 2.8 Schematics of the 3.3V Power Supply
