Thanks for the tip Michael! I'll definitely keep your reccomendation to
use yices2 in mind when setting the default engine in the script (if I
do end up needing to set one, I'm not done yet), and for myself when I
start trying to use nmigen.

In that regard, Luke, after I am done with the scripts and the
modifications to the docs on the wiki, is there some testing
infrastructure that needs to be worked on, or should I try to start
learning to make nmigen HDL contributions to the project? Essentially,
what do you reccomend I do next that would be most helpful to the project?

Here is my code for a working super_prove installation in case you are
interested in trying it out:
