Geoffrey,
Apologies for the lateness of my reply - I've been tied up with so many other things recently, I've had no chance to monitor the Designer's Guide.
No, SpectreRF does not provide a means of doing what you're suggesting. I'm not sure it would be useful, given the fact that the matrices over time are needed for the small-signal analyses.
If the circuit is weakly non-linear, and especially if it is a multi-tone simulation, using flexible balance can save a lot of memory, since you only need to store the harmonic coefficients for a small number of harmonics for each voltage and branch current (put simply).
Also, using QPSS can help if it's a multi-tone simulation, because even with shooting, the solution is partly in the frequency domain, and the time domain information is only needed for the "large" signal.
Andrew.
