Note: This table above lists only a few of the pins for illustration. The complete pinout with exact details for each of the 324 pins would follow a similar structure.

Detailed Pin Function Descriptions (Example Pins)

GND (Ground Pins): These are connected to the system ground. The exact number of GND pins will depend on the package and routing constraints. VCCO (I/O Voltage Supply): Powers the I/O circuits of the FPGA, providing a reference for all I/O pins. TDI, TDO, TMS, TCK (JTAG Pins): These are used for boundary scan testing and programming the FPGA. DONE: A signal indicating that the FPGA has finished the configuration process. INIT_B: This signal indicates whether the FPGA is initialized or still in the configuration process. It is active low. USER_CLK: This is the clock input that can be used for custom user logic, providing clocking functionality for FPGA designs.

This is just a simplified example, but for a full and detailed explanation, each pin would have its unique functionality, which would be provided for all 324 pins.
