fpga refers to field programmable gate array, which is further developed on the basis of programmable devices such as PAL, GAL and CPLD. It appears as a semi-custom circuit in the field of application-specific integrated circuit (ASIC), which not only solves the shortcomings of custom circuit, but also overcomes the shortcomings of the limited number of gate circuits of the original programmable device.
An integrated circuit is a tiny electronic device or component. Using a certain process, the transistors, resistors, capacitors and inductors required in a circuit and wiring are interconnected together, made on a small or several small pieces of semiconductor chips or dielectric substrates, and then packaged in a tube shell to become a miniature structure with the required circuit functions.
The two are different technological components, the structure is not the same, and the use is not the same.
Integrated circuits are divided into analog and digital, and digital and analog hybrid integrated circuits. Fpgas must be in the form of digital VLSI. The digital integrated circuit you design must first use FPGA programming to verify the design scheme is reasonable; Then the simulation can be perfected to verify such a cycle to ensure the correct and reasonable design. FPGA development can be used to validate the design of digital integrated circuits.
