Structure of Field Programmable Gate Array (FPGA)

Reading time: 10 minutes

A field programmable gate array (FPGA) is an integrated circuit designed to be configured by anyone for various purposes like hardware stimulation. In this article, we have demonstrated the structure of FPGA.


A field programmable gate array (FPGA) consists of:

  • Input/ Output Pads
  • Configurable Logic Blocks (CLB)
  • Connection Blocks
  • Switch Blocks
  • Channel Width

Visually, the internal structure of FPGA is as follows:
