In Vivado’s welcome screen, click the Create Project button.Ĭhange the name of the project to ila_tutorialand click on Next. It should work in Vivado version 2020.2 or newer.Įxtract the Zip and open the ila_tutorial.xpr file in Vivado to view the example design, or read the rest of this article to learn to create it from scratch.

You can download the example project and VHDL code using the form below. I’m using the Kintex-7 FPGA KC705 Evaluation Kit, but the methods shown in this tutorial should work on any modern Xilinx FPGA board.
Xilinx Intellectual Property: Virtual Input/Output (VIO). 
Xilinx Intellectual Property: Integrated Logic Analyzer (ILA). Unlike ILA, the VIO IP allows you to virtually drive internal signals inside your FPGA to stimulate or control your design, like driving the RESET signal. The ILA IP helps you easily probe internal signals inside your FPGA and bring them out into a simulation-like environment to monitor them and verify their behavior. The ILA and VIO are free customizable IPs from Xilinx. Use the sidebar to navigate the outline for this tutorial, or scroll down and click the pop-up navigation button in the top-right corner if you are using a mobile device. This article contains multiple screenshots from the Vivado GUI. It is easy, fast, flexible, and has many advanced features that help designers quickly view and check the chosen signals’ behavior. The Integrated Logic Analyzer (ILA) is an alternative that combines the advantages of both previous options. This option is easy, fast, and works well for simple cases, but it is not flexible, scalable, or realistic.Īnother option is to have an external logic analyzer with advanced features that can display and depict these signals’ behavior, but it requires external and relatively expensive equipment. 
One option is to bring these signals to the FPGA pins and connect them to LEDs to see their behavior visually.

That is, gaining access to an internal signal’s behavior in their FPGA design for verification purposes. In many cases, designers are in need to perform on-chip verification. This tutorial covers using the Integrated Logic Analyzer (ILA) and Virtual Input/Output (VIO) cores to debug and monitor your VHDL design in the Xilinx Vivado IDE.
