I used the coupling strategy once so far.  It worked quite well.  The first time through I hand coded everything.  For the second time through, I'm making a code generator.  At the time of writing, the generator is mostly done.  The generator outputs a python module to be integrated in a cocotb test bench and a modelica model.  I'll be trying to use it soon.

Although it's almost certainly full of bugs, I have the generator up on GitHub: https://github.com/adamLange/hdlModelicaInterfaceGen
