FPGA is one of the physical implementations of digital circuits. Compared with ASIC chip, another important realization of digital circuit, an important feature of FPGA is its programmable feature, that is, the user can specify the FPGA to realize a specific digital circuit through the program.
In this article, we talk about FPGA from 5 aspects, what is FPGA, the FPGA architecture, FPGA design flow, the FPGA application and the difference between FPGA and ASIC, let's read on. 
<h2 id="heading-what-is-fpga">Ⅰ. What is FPGA?</h2>
FPGA is a digital integrated circuit chip that can be used to write circuits, and is a chip used to design chips. You can use programming languages ​​to design the circuits you want. In general, the circuit in the single-chip microcomputer has been solidified, and only the program needs to be input, while the FPGA is designed to use the programming language to design the circuit.
The working principle of Fpga is to adopt the concept of Logic Cell Array (LCA), which includes three parts: Configurable Logic Block (CLB), Input Output Block (IOB) and Interconnect.
