You could actually try that out yourself.

There is a simulation benchmark that includes Icarus:

 http://www.veripool.com/verilog_sim_benchmarks.html

If I understand it right you don't have to have verilator installed for
running the benchmark with Icarus.

I tried running the latest develop snapshot 20070227 with it and had to
do a slight modification to the Makefile

In line 26 I had to add a dot '.' to the last -y switch to have it look
like this:

  ICARUS_FLAGS = -o simi -y ../bench -y ../rtl -y . \


Cheers,

Guenter
