FPGA (Field-Programmable Gate Array) is an integrated circuit chip with programmable logic gate arrays that can be configured and reprogrammed according to user requirements. The working principle of FPGA is to combine logic gates and storage units to form a programmable logic circuit. Users can map specific logic functions to the logic gate array of FPGA using programming tools to achieve different digital circuit functions.

The logic gate array of FPGA consists of a large number of Programmable Logic Blocks (PLBs), each PLB containing multiple logic units and storage units. Logic units can implement basic logic functions such as AND gates, OR gates, NOT gates, etc., while storage units can store intermediate results and state information. PLBs are interconnected through programmable interconnect networks, enabling data transfer between different logic units and control signal transmission.

In the design process of FPGA, users first need to write the required logic function description using hardware description languages (such as Verilog or VHDL). Then, the logic function is mapped to the logic gate array of FPGA through programming tools, and a configuration file is generated. The configuration file contains the layout of logic gates, connections, and initialization information of storage units, which can be loaded into the FPGA chip through a programmer.

Once the FPGA chip is loaded with the configuration file, the logic gate array will be initialized according to the information in the configuration file and start executing the user-defined logic function. Users can reprogram the FPGA chip to modify the logic function and achieve different digital circuit designs. Due to its programmability and flexibility, FPGA can achieve different functions without changing the hardware structure, making it widely used in digital circuit design and prototype verification.

In addition to the logic gate array, FPGA also includes other functional modules such as clock management units, input/output interfaces, memory controllers, etc. These functional modules can help users implement more complex digital system designs, such as processors, communication interfaces, image processing, etc. Users can configure these functional modules through programming tools to work in coordination with the logic gate array, achieving more flexible and high-performance digital system designs.

In summary, the working principle of FPGA is to combine logic gates and storage units to form a programmable logic circuit. Users can map specific logic functions to the logic gate array of FPGA using programming tools to achieve different digital circuit functions. FPGA has programmability and flexibility, allowing different functions to be achieved without changing the hardware structure, making it widely used in digital circuit design and prototype verification.
