I do majority of my work on a *nix system.  I do have
access to a Windows machine with Python and MyHDL setup.
On this machine I use the git bash [1].  The git bash
will have `make` etc. (I believe).  Then I also have
`iverilog` and `modelsim`.  Some of the test require
`py.test` [2] to be installed

The test suite has two categories:

    1. core (core and core2)
    2. conversion

The *core* don't require any cosimulation, these you
should be able to run out of the box.

    # setup myhdl, install the latest or create links
    >> cd <clone dir>/myhdl/test/core
    >> make

This will run one set of tests, you should see them
all pass

    >> cd <clone dir>/myhdl/test/core2
    >> py.test

This will run the second set of core tests, again
all should pass.

For the conversion tests you will need a simulator
installed an possibly the myhdl.vpi built and copied.
The Windows machine I have access to, has modelsim.

To run the general conversion (these don't require
the myhdl.vpi)

    >> cd <clone dir>myhdl/test/conversion/general
    >> make vcom  # or make icarus, make GHDL, make vlog

On my linux machine, I have 3 failing tests on the master
branch with `icarus` and 5 wiht `GHDL`.  On the windows
machine I have most tests failing (icarus, GHDL, and VCOM)
... not sure why.  Is this what you are seeing (reporting)?

The toVerilog directories will require the myhdl.vpi, we
can cover these in a follow-up.
