... And you thought there is no free lunch!!!
As they say, the best things in life come
free. I am not sure if that is true for EDA tools too, but you be the judge.
Here is a list of free Verilog tools and utilities. Only those
tools/utilities are listed here, which are absolutely free. That means, there
is no tag attached to it (no "It is a freeeee 30 day trial version" here),
but there may be some limitations on the product.

public license (GPL).
VBS : Jimen Ching's school project
has turned into a full-fledged behavioral Verilog simulator.
