Stv-process

Stv-extract-relevant-signals

Pull out the fully general expressions for the signals that we care about, and bind them to the bit names of the simulation variables.

Signature
(stv-extract-relevant-signals extract-alists out-alists acc) → *
Arguments: extract-alists — The stv-extraction-alists we obtained from stv-compile.; out-alists — The list of output alists from the fully general simulation, e.g., from stv-fully-general-simulation-run.; acc — An accumulator to extend, which should initially be nil.

We walk down the extract-alists and out-alists together, extracting the expressions for the signals that we care about at each phase, and naming them with the output simulation variable bit names.
