Thank you, Walter & Ambrish.
I understand the bit about Init_Returns_Impulse = TRUE being necessary for
statistical simulation (at least on a rudimentary level).
If both these parameters are set to TRUE and we're doing time domain
simulation, is there any possibility that the simulator might apply
equalization twice? Of does the simulator get to pick which way to apply
equalization in this case?

Greg,
If Init_Returns_Impulse = TRUE, then the IR output if Init contains the
impulse response of the channel modified by the equalization of the model.
This is independent of the GetWave_Exists = True or False.
If GetWave_Exists = TRUE, then the waveform output of GetWave is the input
to GetWave modified by the equalization of the model. This is independent
of the Init_Returns_Impulse = True or False.

If Init_Returns_Impulse = TRUE and GetWave_Exists = TRUE, what is GetWave
supposed to do? It can't do any equalization, right? Equalization is
happening in Init if Init_Returns_Impulse = TRUE.
Thanks in advance.
