Clock Domain Crossing (CDC)

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 Versal devices, traditional trial-and-error tuning of implementation strategies can lead to long debug cycles and … Continued

The RF Analyzer in AMD Vivado represents a significant advancement in RF signal processing and analysis, tailored to address the complex requirements of modern communication systems, radar applications, and more. By bridging sophisticated configuration capabilities with user-friendly GUI controls, the tool equips engineers with the precision and flexibility required for optimal ADC (Analog-to-Digital Converter) and … Continued

AMD Versal AI Engine and AI Engine-ML. Which is right for you?

By

The AMD Versal architecture introduced a new adaptable compute domain, the AI Engine. The AI Engine is a powerful coprocessor that can be used to implement vectorized algorithms that otherwise would be resource intensive on a traditional FPGA. While the amount of AI Engine tiles varies across the Versal lineup, the AI Engine itself is … Continued
Configurable Logic Block (CLB)

The Configurable Logic Block – A Quick Look

By

In this post, we will quickly review the Configurable Logic Block (CLB) and how it has changed over the years.  In 1984, Xilinx introduced the first FPGA to the world, the XC2064. This FPGA formed the backbone of later device families and the design flow leveraged the Xilinx XACT tool.  Nearly 40 years later, FPGAs … Continued
Cross Triggering

Unlocking the Power of Cross Triggering on FPGAs

By

Understanding Cross Triggering (and why it's your friend) Cross triggering is a useful technique to help with debugging FPGAs. Field-Programmable Gate Arrays (FPGAs) are extremely versatile hardware platforms known for their ability to implement custom digital logic in the matter of seconds through the uploading of a bitstream. The applications of FPGAs range through many … Continued
