I would not accept your proposed changes. I would, however, accept the
following:
Model_Specific parameters shall not be intended to be used for
purposes which may alter past, present or future simulation results
in any way. In case there is a need to use parameters of (Usage
Out) or (Usage InOut) for such purposes, those parameters shall be
defined as Reserved_Parameters, with usage fully documented in the
specification. Model_Specific parameter usage is compliant if it
does not use the values of Out or InOut Model_Specific parameters to
modify the inputs to, or outputs of, any past, present, or future
calls to any AMI model in the simulation.

Arpad,
I suggest an alternative to the following paragraph in the Usage Out
and InOut BIRD
Model_Specific parameters must not be used for purposes which may
alter past, present or future simulation results in any way. In case
there is a need to use parameters of (Usage Out) or (Usage InOut) for
such purposes, those parameters shall be defined as
Reserved_Parameters and fully described in the specification.
Proposed replacement paragraph:
A Model is compliant if when presented with a set of inputs as
described by its .ami file and other inputs as described in the
approved IBIS specification gives the same outputs (within acceptable
numerical precision) on any hardware platform that the model supports.
The various IBIS AMI test benches can be used to validate this. A
simulation is compliant if it does not use the values of Out or InOut
Model_Specific parameters to modify the inputs to any future calls to
any AMI model in the simulation. A simulation is compliant if it does
not use the values of Out or InOut Reserved_Parameters to modify the
inputs to any future calls to any AMI model, unless such modification
to inputs to any AMI model in the simulation is fully described in the
IBIS specification. There shall be no prohibition from a User to
direct a simulation to use a compliant model in a non-compliant way.
