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

Understanding the AXI Protocol: Applications and Functionality

By

The AXI protocol is powerful and easy-to-use for connecting modules within SoCs and FPGAs. Intro to the AXI Protocol AXI (Advanced eXtensible Interface) is an interface for connecting modules within an SoC or an FPGA. It is fully synchronous and can be as wide and as fast as needed to meet transfer requirements between modules. … Continued

Leveraging Vivado QoR Reports to Optimize FPGA Design Performance

By

Vivado QoR Reports are powerful tools in the Vivado Integrated Development Environment that help designers enhance the Quality of Results (QoR) for their FPGA designs. These include the DRC Report, the Methodology Report, the Design Analysis Report, the QoR Assessment Report, and the QoR Suggestions Report. The Vivado QoR Reports predict potential improvements that designers … Continued
Finite State Machines (FSMs)

Stop Having So Many States in Your Finite State Machines! – A Guide to Using FSMs

By

What starts as a simple task can quickly spiral into something far more complex—whether it's home repairs, birthday parties, or, unfortunately, Finite State Machines (FSMs). In Hardware Description Language (HDL), it’s easy to keep adding states—“wait” states, nested states, and so on. While these states are meant to simplify logic and improve maintainability, they often … 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
