If simulation means Spice to you, you are 20 years behind.

Looking to the past ...  Simulations of things like this were 
(and are) often done on a proprietary commercial simulator 
"Saber", using a proprietary modeling language "Mast".  
Matlab/Simulink is also popular (and proprietary).

Looking forward ...  Things like this can be done very well in 
Verilog-AMS, which has a published standard, cleaner syntax, and 
several commercial implementations.  Many users of Saber and 
Mast are switching over.   Gnucap provides partial support for 
Verilog-AMS, and is working on more complete support.
