history
Project history and usage
Icarus Verilog is a long-running free Verilog compiler and simulation toolchain. It compiles Verilog and a growing subset of SystemVerilog, usually emitting `vvp` bytecode that is then executed by the `vvp` runtime.
Project history
The project README describes Icarus Verilog as a compiler for the IEEE 1364 Verilog HDL, with partial IEEE 1800 SystemVerilog support, and emphasizes that it is a compiler whose generated code is handled by back-end tools rather than a monolithic traditional simulator.
Its source tree carries a 2000-2026 Stephen Williams copyright line, and its release tags span early 0.8/0.9 series tags through v13_0. The documentation site includes user, target, and developer manuals, reflecting a tool that has accumulated both end-user workflows and internal extension points over decades.
Adoption history
Icarus Verilog is widely packaged across Unix-like and developer package ecosystems, including Homebrew, Debian/Ubuntu, Fedora, Arch, Nix, MacPorts, Chocolatey, Scoop, winget, and openSUSE according to the input package metadata. That spread mirrors its role as an accessible simulator for students, hobbyists, CI jobs, and open hardware projects.
How it is used
The basic workflow is to compile Verilog sources with `iverilog -o output input.v` and run the compiled result with `vvp output`. The documentation also covers command files for larger designs, root module selection, waveform viewing, VPI modules, multiple code-generation targets, and developer internals.
Why package nerds care
Icarus Verilog is one of the canonical open-source EDA packages: old enough to have autotools-era build expectations, important enough to appear in nearly every serious package set, and small enough to be a default answer when a package manager needs a Verilog simulator for tests or education.
Timeline
- 2000: Source tree copyright range begins for Stephen Williams's Icarus Verilog codebase.
- 2006: Public tags include v8-s20060822 and the 0.8/0.9 release line.
- 2010s: v10 and v11 tags mark continued evolution of the compiler/runtime toolchain.
- 2020s: v12_0 and v13_0 tags mark later standard-conformance, diagnostics, and runtime stability work.
