There is an incomplete Verilog code generator for Icarus Verilog.
In principle, the idea here is to completely compile your program
with Icarus Verilog, and use the -tverilog code generator to then
write the compiled design back out in Verilog.

The obvious problem with that is that it needs work. But it shouldn't
be too hard to get it working on netlist-like verilog input. I
would recommend working with the current snapshot.
