I'm likening your project to the modules being the sum/gain/integrate/etc

designed the individual modules, they'll be static (likely replicated)
with the real changes happening in the backplane wiring?

 I think the one part you are not understanding is the purpose of the
patch panel. So, it would be like so:
 - Fixed analog component modules — integrators, multipliers, and such
   like — connect to the back plane. These modules are normally not
   changed out except for repair, testing, and expansion.
They "plug in" to the backplane.

- Cables from the patch panel(s) connect to the backplane. Wiring on the
   backplane connects these cables to the component modules. This wiring
   is not normally changed unless adding new patch panels or some
   fundamental redesign of a patch panel port.
So, all these are doing is acting as convenience functions; giving
you access to the backplane without having to directly wire ON the
backplane.

- The patch panels(s) have a bunch banana jacks allowing me to quickly
   interconnect the inputs and outputs of the various analog components.
   These connections are frequently changed — every time I set up a new
   simulation.
OK.  I was assuming the backplane was acting as your patch panel,
hence needing reasonably robust means of reusing connection points.

This is how it works with my current analog computer I built, except
that there is no backplane. Rather, the wires from the patch panel
cables connect directly to terminal blocks on the analog component
modules.
So, the backplane is just a packaging convenience?
