What is FPGA and is it useful?

FPGA is the product of further development based on programmable devices such as PAL and GAL. As a semi-custom circuit in the field of application specific integrated circuit (ASIC), it not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of limited gates of the original programmable devices.

FPGA design is not a simple chip research, but mainly uses the mode of FPGA to design products of other industries. Different from ASIC, FPGA has been widely used in communication industry. Through the analysis of the global FPGA product market and related suppliers, combined with China's current actual situation and domestic leading FPGA products, we can find the future development direction of related technologies, which plays a very important role in promoting the overall improvement of China's scientific and technological level.

Extended data:

FPGA device is a semi-custom circuit in ASIC and a programmable logic array, which can effectively solve the problem of less gate circuits in the original device. The basic structure of FPGA includes programmable input and output unit, configurable logic block, digital clock management module, embedded block RAM, wiring resources, embedded dedicated hard core and underlying embedded functional unit.

FPGA has been widely used in the field of digital circuit design because of its rich wiring resources, repeatable programming, high integration and low investment. The design process of FPGA includes algorithm design, code simulation design and board-level debugging. Designers and actual needs establish the algorithm architecture, use EDA to establish the design scheme or HD to write the design code, ensure that the design scheme meets the actual requirements through code simulation, and finally conduct board-level debugging, and use configuration circuits to download relevant files to FPGA chips to verify the actual operation effect.
