Unless you run a full SPICE model, including all the imperfections

1. it isn't easy anymore,
2. it very probably won't run in real time.

And without all that, and idealised analog circuit is just another
format for some simple mathematical equations, a simple abstraction.
Engineers use it all the time to describe all sorts of systems that
are not electronic at all, in the same way they use mechanincal
abstractions such as mass/spring/damping systems. Idealised circuits
are just another notation for maths, an as such they provide nothing
new. They just translate into the standard filters etc. that DSP code
authors use all the time. It's an illusion to think that youd could
generate any 'magic' DSP code form them that can't be obtained in
the normal way. On the contrary, you're likely to get inferior quality
results as things such as quantisation and numerical stability are
blissfully ignored.
