What is a FPGA?

An FPGA (Field-Programmable Gate Array) is a semiconductor device that can be configured or reconfigured by the user after manufacturing. Unlike traditional integrated circuits with fixed functions, FPGAs offer high flexibility, allowing engineers to tailor them for specific tasks and adapt to evolving system requirements.

An FPGA consists of an array of programmable logic blocks and interconnects, which can be customised to create complex digital circuits. This makes FPGAs ideal for applications requiring flexibility, speed, and parallel processing, such as telecommunications, automotive, aerospace, and industrial sectors.

Why use an FPGA instead of other types of ICs (integrated circuits)?

FPGAs are preferred over other integrated circuits for several reasons. Firstly, they offer unmatched flexibility, as they can be reconfigured when requirements change, making them ideal for applications that may need updates or modifications. Additionally, FPGAs excel in parallel processing, enabling them to perform multiple operations simultaneously, unlike CPUs , which handle tasks sequentially. Moreover, FPGAs can reduce development time and costs by eliminating the need for custom hardware design .

How can I configure an FPGA?

Since FPGAs have no fixed function, they need a configuration to enable the device’s logic circuits and interconnects to adapt to a specific application’s requirements.

  1. Design Entry
    • Write the logic functions using Hardware Description Languages (HDLs) such as VHDL or Verilog.
  2. Simulation and Verification
    • Run simulations to check the logic, ensuring there are no errors before proceeding. This step can be repeated throughout the design process.
  3. Synthesis
    • Convert the HDL code into a gate-level netlist, using a synthesis tool, which represents the circuit in terms of logic gates.
  4. Place and Route + Bitstream Generation
    • Map the gate-level netlist to the physical resources (logic blocks, interconnects) using a vendor-specific Place&Route tool, that generates the configuration bitstream for the FPGA.
  5. Download Bitstream onto the FPGA
    • Transfer the bitstream to the FPGA using a programming tool or cable connected to the FPGA device.
  6. Post-Configuration Testing and Verification
    • Test the FPGA in real-world scenarios, comparing the output against the expected behaviour. Debug and re-configure if needed.

Many tools, including vendor-specific and third-party software, are available to aid in FPGA configuration.

Fields of application for FPGAs

FPGAs find applications in a wide range of industries due to their versatility.



In telecommunications, FPGAs are used for signal processing and data transmission. The automotive industry employs FPGAs for advanced driver-assistance systems (ADAS) and infotainment systems. FPGAs play a crucial role in aerospace and defense, used in radar systems, communication devices, and electronic warfare. The medical field benefits from FPGAs in imaging systems and diagnostic equipment. With the rise of artificial intelligence and machine learning, FPGAs are increasingly utilized for accelerating complex algorithms.
