This is basically correct, the parameters you need for your module
would also go in that declaration. You'll also need to add a
"SimObject('myfile.py')" line to a SConscript. You of course need to
write a whole lot of C++ code to model your device. Look at the other
devices in the src/dev directory to get an idea of what needs to be
done.
