Verilog vs VHDL: Choosing the Right HDL for FPGA Design

By

The two dominant hardware description languages (HDLs), Verilog and VHDL, are both well-established, widely supported, and capable of describing complex digital systems. While each language can be used to create functionally identical hardware, they differ significantly in syntax, style, and design philosophy. When developing FPGA designs, selecting the right HDL is one of the first … Continued

Demystifying I/O Timing Constraints

By

I/O timing constraints can be daunting, even for experienced FPGA designers. A common misconception is that these constraints somehow fix skewed input signals. They don’t. While synthesis and implementation tools can tolerate some signal misalignment, constraints are always required to determine whether your design will function correctly, as-is. If precise alignment is necessary, it must … Continued

Clock Domain Crossing (CDC) Made Simple: Best Practices for Vivado Users

By

Managing clock domain crossing (CDC) is one of the most critical — and sometimes confusing — challenges in FPGA design. With modern designs often spanning multiple clock domains, ensuring safe data transfer across these domains is essential to avoiding metastability, timing issues, and unreliable system behavior. In this post, we’ll walk through how to approach … Continued

Achieving Timing Closure with Vivado Intelligent Design Runs

By

Vivado Intelligent Design Runs (IDR) are a powerful feature that helps designers achieve timing closure more efficiently. Timing closure is often one of the most persistent and frustrating challenges in FPGA development. For complex designs, especially those targeting UltraScale and UltraScale+ devices, traditional trial-and-error tuning of implementation strategies can lead to long debug cycles and … Continued

Understanding What High-Level Synthesis (HLS) Is: Bridging the Gap Between Software and Hardware

By

In electronics and digital design with FPGAs and SoCs, the demand for more efficient, powerful, and faster hardware is unrelenting. Engineers and developers require ways to optimize their designs, making them faster and more energy efficient. One of the transformative technologies available to address this challenge is High-Level Synthesis (HLS). It plays a crucial role … Continued
Versal Adaptive SoC (ASoC)

Versal ACAP vs Versal Adaptive SoC

By

You may have heard the term Versal ACAP. Now, there’s Versal Adaptive SoC. What are they? What’s the difference? Let us explain. What is the Versal ACAP? In 2018, AMD Xilinx introduced the first adaptive compute acceleration platform, commonly known as an ACAP. The ACAP provides the robust functionality of an FPGA with adaptable programming … Continued
