Danil,
There are a number of models that are truly LTI, and only have an Init. The
GetWave_Exist=False is how the ami file tells the EDA tool that this is the
case.

Dear colleagues,
I would like to clarify one basic principle of AMI modeling, hoping that all
of us agree with it.
I believe that the model writer should never do a double-counting: if he
modified the channel impulse response in Init() to model some effect, he
should not model this effect in Getwave(). So he cannot put the "true" model
in GetWave() and it's linear approximation in Init(). If both types of
behavior are expected, there should be two models (or some internal flag
that changes the behavior of the model).
If this assumption is true, statistical (linear) simulator always works with
Init() function of the model, while pattern-dependent (non-linear) simulator
works with both Init() and GetWave() and I do not see any necessity for
Get_Wave_Exists flag.
Best,
Danil
