Do you mean the modelling of circuits to emulate the sonic 
characteristics of analog or digital/analog gear (something like 
https://ccrma.stanford.edu/~dtyeh/ for instance)? The other 
interpretation (circuits used for modelling the behaviour of other 
circuits) does not make a lot of sense to me in the context of Line6 
modelling pdeals. Those are DSP based devices. I guess the exact 
approach/set of algorithms they use is proprietary.
