Specify the top level module to elaborate. Icarus Verilog will by default
|

choose the only module that has no ports. However, this simplistic

heuristic is often not sufficient, and sometimes not what is wanted

anyhow.

choose modules that are not instantiated in any other modules, but

sometimes that is not sufficient, or instantiates too many modules. If

they will be used as root modules instead.
