Description A quick reference manual for the two most popular Hardware Description Languages (HDL): VHDL and Verilog. This app is written by engineers, for engineers. For every construct in VHDL, provides the equivalent in Verilog, and vice-versa. VHDL (VHSIC-HDL, Very High Speed Integrated Circuit Hardware Description Language) is a hardware description language used in electronic design automation to describe digital and mixed-signal systems such as field-programmable gate arrays and integrated circuits. VHDL can also be used as a general-purpose parallel programming language.
Welcome to the home page for Icarus Verilog. This is the source foryour favorite free implementation of Verilog!What Is Icarus Verilog?
Icarus Verilog is a Verilog simulation and synthesis tool. Itoperates as a compiler, compiling source code written in Verilog(IEEE-1364) into some target format. For batch simulation, the compilercan generate anintermediate form called vvp assembly. This intermediate formisexecuted by the ``vvp' command. For synthesis, the compiler generatesnetlistsin the desired format.The compiler proper is intended to parse and elaborate designdescriptions written to the IEEE standard IEEE Std 1364-2005.This is a fairly large and complex standard, so it will take some timeto fill all the dark alleys of the standard, but that's the goal.
Icarus Verilog is a work in progress, and since the languagestandard is not standing still either, it probably always will be. Thatis as itshould be. However, I will make stable releases from time to time, andwillendeavor to not retract any features that appear in these stablereleases.The quick links above will show the current stable release.
The main porting target is Linux, although it works well on manysimilar operating systems. Various people have contributed precompiledbinaries of stable releases for a variety of targets. These releasesare ported by volunteers, so what binaries are available depends on whotakes the time todo the packaging. Icarus Verilog has been ported to That OtherOperatingSystem, as a command line tool, and there are installers for userswithoutcompilers. You can compile it entirely with free tools, too, althoughthereare precompiled binaries of stable releases.

Where is Icarus Verilog?
NOTE: This is aquick summary of where to get Icarus Verilog. for more completedownload and install instructions, look -->here.
The Current release is available in source and a variety of binaryforms in the FTP directory <ftp://ftp.icarus.com/pub/eda/verilog/v11/>. Updates to the stable release may be made from time to time tofix problems, but there should be no compatibility issues within thisversion series. This will continue to be maintained until renderedobsolete by a new stable release.
Development snapshots are made fairly often, and made available inthe FTP directory <ftp://icarus.com/pub/eda/verilog/snapshots>.The files are gzip compressed tar files that contain the source andmakefiles. These snapshots follow development progress, and, althoughthe latest features are included in this source, compatibility fromsnapshot to snapshot is not guaranteed.

And finally, the current 'git' repository is available for read-onlyaccess via anonymous git cloning. This allows for those who which totrack my progress and contribute with patches timely access to the mostbleeding edge copy of the source. Access the git repository of IcarusVerilog with the commands:
gitclone git://github.com/steveicarus/iverilog.git
Vhdl Tool For Mac Os
From here, you can use normal git commmands to update your sourcetothe very latest copy of the source. See the InstallationGuide for details on how to access and compile the git repository.
A Test Suite?
There is also a test suite available. The test suite is also accessibleas the ivtest github.com project, available here: <https://github.com/steveicarus/ivtest>. Access the git repository of the test suite with the command:Since the test suite is simply an ongoing accumulationof tests, there are not typically any releases, per se. Only the gitsource.
