This is a really good article (IMHO at least) in SOS about how classic analog gear is digitally simulated using different techniques and platforms, mostly computer plug-ins but also DSP hardware as well.
Plug-in Modelling
It discusses actual circuit modeling at the component level (like the AXE uses for some of its blocks) as well as the use of test signals (like the Kemper Amplifier Profiler) to determine the transfer functions of complex non-linear circuits. It also touches on dedicated DSP processors (again like the AXE uses) vs. computer plugins.
Representatives from companies that are industry experts chime in on their philosophies of the best ways to go about it, specific hardware they've created DSP code for, the limitations of different methods, etc. I found it to be a very enlightening and extremely interesting article. I'm actually only about 3/4 of the way through it myself but thought it worth posting a link to before I nod off tonight.
Enjoy (or not!).
Thanks.
