So let us start. There is also a test suite available. You can use this feature to prevent instantiation of unwanted roots. Next, let’s take the Icarus Verilog compiler and simulator for a test run.

The command file technique clearly supports much larger designs simply by saving you the trouble of listing all the source files on the command line. Various people have contributed precompiled binaries of stable releases for a variety of targets. These snapshots follow development progress, and, although the latest features are included in this source, compatibility from snapshot to snapshot is not guaranteed.

The simplest is to list the files on the command line: Documentation is available on cocotb. There are two releases of this. These are articles that describe in clear prose, with examples, the basics of using Icarus Verilog.


That is as it should be. This is a fairly large and complex standard, so it will take some time to fill all the dark alleys of the standard, but that’s the goal. Then, open the disk image and run the installer. I’ll be adding a credits verjlog someday, although the source distributions do in general name names. Open the zipfile, and drag the tutorial1 folder to your Desktop.

Finally, close and re-open the command prompt and try again. If this command fails, make sure the tutorial1 folder was successfully created on the Desktop, and not, for instance, in your Downloads folder. Icarus Verilog chooses as roots There can be more than one root all the modules that are not instantiated by other modules. Under Windows, the commands are invoked in a command window.

And there it is, the program has been executed. The two major parts cover working with Icarus Verilog and Berilog Verilog details. Although both sections are written in prose with examples, the second section is more detailed and presumes the basic understanding of the first part.

The links here contain more advanced information on select subjects. If you don’t already have one, I suggest Sublime Textwith the Sublime Verilog extension installed.

Getting Started

What sort of output the compiler actually creates is controlled by command line switches, but normally it produces output in the default vvp format, which is in turn executed by the vvp program. Next, execute the compiled program like so: Icarus Verilog is a work in progress, and since the language standard is not standing still either, it probably always will be.


Next, you should choose either Mac or Windows for instructions on installing Icarus Verilog and verifying that everything is working. Welcome to the home page for Icarus Verilog. Open up the system properties control panel, and edit the environment variables for your account.

Accept all of the default choices as you click through the installation. Updates to the stable release may be made from time to time to fix problems, but there should be no compatibility issues within this version series. Simbus Simbus supports distributed simulations of bussed systems.

User Guide

Access the git repository of the test suite with the command: The “iverilog” command is the compiler, and the “vvp” command is the simulation runtime engine. Go to Downloads on the left and click the link to get Scansion. It will create a folder on your Desktop called tutorial1.
