All,
Update wording is now:
The EDA Tool/Simulator shall use the value of these Jitter and Noise
parameters directly if they are Usage Info. If they are Usage Out, then
the EDA Tool/Simulator shall use their values generated by AMI_Init. The
models AMI_GetWave function may return different values for these
parameters than the values returned by AMI_Init; the EDA Tool/Simulator
may report the values of such parameters to the user, but the EDA
Tool/Simulator may not change any inputs to AMI models or change other
result of the simulation based on the values returned by the parameters in
this BIRD by AMI_GetWave.

Walter,
I don't remember all the details of these parameters, so I will
ask a question which may be somewhat uneducated.
Are any of these parameters used to "modulate" the bit pattern,
or influence any other input that is passed into the AMI model
by the tool? In case the answer is yes, I would suggest to
reword the last part of your new text:
"but the EDA Tool/Simulator may not change any other result of the
simulation"
This refers to modifying "results", but does not prohibit modification
of inputs, which should also be included in this statement. I know
changing the inputs might indirectly also modify the results, but I
don't like to leave this vague like that.
Also, for the sake of consistency and completeness, I wonder if
this sentence should also mention past, present or future results,
as was Suggested by Scott for the InOut/Out BIRD draft.
Thanks,
Arpad

All,
I have added these lines to BIRD 123.1 (Jitter BIRD). Please review this
and make suggested changes before I submit it to the Open Forum.
Note:
The EDA Tool/Simulator shall use the value of these Jitter and Noise
parameters directly if they are Usage Info. If they are Usage Out, then
the EDA Tool/Simulator shall use their values generated by AMI_Init. The
models AMI_GetWave function may return different values for these
parameters then the values returned by AMI_Init; the EDA Tool/Simulator
may report the values of such parameters to the user, but the EDA
Tool/Simulator may not change any other result of the simulation based on
the values returned by the parameters in this BIRD by AMI_GetWave.
