Arpad: I understand the concern. An alternative paragraph might state: Note: The EDA Tool/Simulator shall use the values of the Jitter and Noise parameters directly (or as selected by the user according to the parameter Type descriptions) if they are Usage Info. If they are Usage Out, then the EDA Tool/Simulator shall use the values returned by AMI_Init. The model's 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 input to AMI models or change any result of the simulation based on the values returned for the Jitter and Noise parameters by AMI_GetWave. Can you suggest improvements?

The last sentence does not sound all that much better this way either. But in addition, I just realized that this entire note only talks about what the EDA tool should do. It doesn't say what the responsibilities of the model maker is. I think we need to spell out that if any of these parameters is Usage Out, the model maker has to make sure that the Init function returns a valid value for the EDA tool, and then we can mention that they can also return other values in GetWave, but those will not be used by the EDA tool or the model in any way to have an effect on the simulation, or its results. I am getting nitpicky now, but I also wonder about the word "directly" in the first sentence. I understand the intent, meaning "from the .ami file not from the AMI model", but to some the word "directly" might mean "without user intervention" in the context of the EDA tool providing a GUI for the user to select a specific value. This can't be the case, since some types might require user selection (list, range, etc.), but the word "directly" might imply that.

The paragraph also contains a self-reference to a BIRD. I would reword the last clause from Note: The EDA Tool/Simulator shall use the values 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 model's 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 for the parameters in this BIRD by AMI_GetWave.

Is this ok?

I would like to request that the following sentence be corrected, because it is grammatically incorrect, and because of that not clear (red emphasis added to point to the problem area): ".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."
