In today’s tech landscape, data is the foundation of innovation. Efficient and accurate data acquisition is critical for scientific research, industrial automation, medical diagnostics, and more — and that’s where Data Acquisition (DAQ) systems come into play. Among various DAQ technologies, systems based on Field-Programmable Gate Arrays (FPGAs) have garnered significant attention for their exceptional performance and flexibility.

An FPGA is like a chip that can be “reshaped” to meet specific requirements. It enables high-speed, parallel processing of large volumes of data, achieving ultra-low latency and high performance that traditional processors often struggle to deliver. This makes FPGAs a powerful choice for DAQ applications that demand high throughput and precise timing control.

However, unlocking the full potential of FPGAs comes with its own set of challenges. In this article, we’ll explore the key obstacles on the road to high-performance data acquisition.

1. Advantages of FPGA-Based DAQ

Before we delve into the challenges, let’s first take a quick look at the compelling advantages of FPGA-based DAQ systems:

• Unmatched speed and parallelism: FPGA logic units can work simultaneously, like thousands of miniature processors operating in parallel, effortlessly handling data rates in the range of gigabytes or even tens of gigabytes per second.
• Millisecond-level low latency: With direct hardware-level data routing, FPGAs avoid the delays typical of software-based forwarding—critical for real-time control and response.
• Highly customizable: The programmable nature of FPGAs allows hardware logic to be tailored to specific application needs, achieving optimal performance-to-power ratios.
• Flexibility and upgradability: Once deployed, FPGAs can be reprogrammed to upgrade features and extend the lifecycle of a system.

2. Six Challenges of Implementing High-Performance FPGA-Based DAQ

Despite its significant advantages, implementing an FPGA-based DAQ system is not without challenges. Key obstacles include:

• Hardware Design & Debugging:
  Designing FPGA boards is highly complex, requiring precise control of high-speed signal integrity (such as impedance and trace length), stable power delivery, and effective thermal management. This demands deep expertise in hardware engineering.
• HDL Programming:
  FPGA development involves using hardware description languages like Verilog or VHDL for parallel system design. Managing a large number of concurrent tasks can be difficult, and HDL code is often extensive, hard to debug, and less readable and maintainable. It requires a different mindset compared to traditional software development.
• Hardware-Software Co-Design:
  Achieving a smooth integration between FPGA firmware and host software is essential. This includes implementing communication interfaces (e.g., PCIe, Ethernet, USB), designing protocols, developing drivers, and providing APIs to ensure reliable and efficient data transfer.
• Testing & Verification:
  The system’s complexity calls for rigorous validation, including functional simulation, timing verification, hardware-in-the-loop (HIL) testing, and stress testing to guarantee stability and reliability.
• Talent & Learning Curve:
  FPGA development requires strong knowledge in digital circuits, signal processing, FPGA architecture, and toolchains. The steep learning curve and shortage of experienced engineers increase both development cost and time.
• Cost & Project Timeline:
  Initial investment can be high due to the cost of high-end FPGAs, EDA tools, and IP cores. The development cycle is often lengthy due to complex design and validation processes. However, the resulting performance, reliability, and customization capabilities make it a valuable long-term solution for demanding applications.
