FPGA. Among them, VCCIO0 is the power supply pin of FPGA BANK0.
Similarly, VCCIO1 ~ VCCIO3 are the power supply pins of FPGA BANK ~
BANK3 respectively. In the development board, VCCIO is connected to 3.3V
voltage. Both pins are 3.3V input and output. VCCA is the FPGA analog power
supply pin, which is connected to 2.5V, VCCD_PLL is the FPGA phase-locked
loop power supply pin, and also connected to 1.2V. The power connection
diagram of the FPGA chip is shown in Figure 3-4.

In addition, there are many pins on the FPGA that need to be connected to
GND to ensure a stable ground reference inside the FPGA. The GND
connected to the FPGA is shown in Figure 3-5
