The Qucs solvers can be used as a shared library, qucsator is actually 
just a thin wrapper for this library now. With special elements in your 
circuit you can externally control voltage sources etc. at every time 
step. This can run either 'synchronously' i.e., you set voltages etc. on 
every single time step, or 'asynchronously', where you set voltages in 
between multiple steps and they are interpolated at the next steps.

Is it possible to do the same or similar with gnucap?

Based on the above I also created a matlab/octave interface based on mex 
files for direct data communication with the simulation during 
simulation execution from these languages to allow joining to larger 
simulations.

Richard
