## Testing

Running the included testbenches requires MyHDL and Icarus Verilog.  Make sure
that myhdl.vpi is installed properly for cosimulation to work correctly.  The
testbenches can be run with a Python test runner like nose or py.test, or the
individual test scripts can be run with python directly.
