The Icarus Verilog Wiki Edit

This is the main page for the Icarus Verilog[1] documentation. From here, branch out to the different sorts of documentation you are looking for. In all cases, the documentation is in wiki form, so that you can update or improve it (although I encourage discussion first before making major changes.)

This wiki in general presumes at least a basic working knowledge of the hardware description language Verilog. For basic information about the purpose and provenance of the language itself, the best starting point is the Wikipedia article here. If you are looking to learn the language in detail, then there are many books on the subject.

And of course ultimately it all comes down to the official language reference, IEEE Std 1364-2005 (not free) from the IEEE. Recently IEEE 1800-2012 version of SystemVerilog LRM (which is a superset of 1364 LRM) is made available free via GET program, see:

The "ABOUT" page has more information about this wiki, including pointers to editing tutorials.
