Because the power supply of Artix-7 FPGA has the power-on sequence
requirement, in the circuit design, we have designed according to the power
requirements of the chip, and the power-on is 1.0V->1.8V->1.5
V->3.3V->VCCIO.
Part 4: FPGA Chip
As mentioned above, the FPGA model we use is XC7A35T-2FGG484I,
which belongs to Xilinx's Artix-7 series. The speed grade is 2, and the
temperature grade is industry grade. This model is a FGG484 package with
484 pins. Xilinx ARTIX-7 FPGA chip naming rules as below
