Kinda, but I was curious how long it would comparatively
take to generate a bitstream starting with a myhdl file.

I don't have an R2 (or 1) to test but the following is
an example starting with a myhdl file, generating a
bitstream for an icestick using the open-source tools [1].

I built this into some automation stuff I have used in
the past.  Running the example on my old'sh ubuntu system
I get:

    >> time python ex_icestick.py
    real   0m3.6s

The above converts the simple myhdl file, then runs the
yosys/arachne/icestorm to generate the bitstream.  I
don't have an icestick so I couldn't test it.

Regards,
Chris
