This is the user guide: a collection of articles on how to use Icarus Verilog effectively. The two major parts cover working with Icarus Verilog and Icarus Verilog details. The first part contains articles that describe how and why things work, and the second part contains more advanced aspects of using Icarus Verilog. Although both sections are written in prose with examples, the second section is more detailed and presumes the basic understanding of the first part.
Working with Icarus Verilog Edit
These are articles that describe in clear prose, with examples, the basics of using Icarus Verilog. Each article covers a significant aspect of using Icarus Verilog in the real world.

Add-on Products Edit
These are some add-on products and 3rd party utilities that make working with Icarus Verilog a more complete user experience.
- GTKWave is a waveform/VCD dump viewer that is well supported by Icarus Verilog.
- Covered is a coverage analysis tool. It can be found here.
- Simbus supports distributed simulations of bussed systems.
- This is a RTL level rule checker. It is developed as an IVL_TARGET of iVerilog. There are two releases of this. One that works with iVerilog 0.8.7 and the other which works with iVerilog 0.9.3. More details are available here
- Cocotb uses VPI to embed the Python interpreter into the simulator and provides a Python library for accessing and assigning signal values, traversing the simulation heirarchy and writing regression tests. Documentation is available on cocotb.readthedocs.org
