Use correct terminologies.
Still I can't know how degree you know modeling and various simulator as well as your signal processing scheme.

than they can be simulated by the same analog simulator.
"
than?" Is it
Verilog-A ?
What is
same as ?

What is "carry wave" ? Is it "Carrier Wave" ?
All three signals are input signals ?
How do they interact each other ?
How much of higher order harmonics do you expect for each tone, 5Hz, 5kHz and 500kHz ?
flz wrote on Jul 2nd, 2009, 2:29am:are there any simulating strategies that can simpfy the simulation for such systems in pure circuits simulation field?
If there is no hidden state in models, you can use Multitone Steady State Analyis such as QPSS or Envelope Analysis.
Here there are many possibilities in how to apply QPSS or Envelope Analysis for your target system.
But I can't give you clear suggestion since your descriptions or explanations about your targets are still very very poor.
flz wrote on Jul 2nd, 2009, 2:29am:ps: Usually the equations of the structures part are much more than the circuits part,
and there are connected by coupled models, such as electrode plate,
and we can modify the simulator engine we used.
I can't understand what you mean ?
Do you make original simulator ?
