It does, although I'm not familiar with the simulation tools involved.

We also still have the task of getting a regenerated bitstream working
right on ZedBoard / Parallella board - with no new features, but also
not breaking any of the existing functionality, right?  Is this also
(still) on your priorities list (just not exactly a bcrypt topic, so not
mentioned in this specific posting of yours)?
