Scott, Because if a User wants an EDA Tool to use an AMI Out parameter in a way that the User wants to there should be no rule that prevents an EDA Tool from doing it.

The User reads the Models Owner's Manual 2. The User understands the channel that this model is going to work in 3. The User decides how to set up simulations based on the channels operating conditions and the Models Owner's Manual. 4. The Model Owner's Manual needs to explain to the User what the models can do, what its inputs are and what its outputs are. The model has to explain to the User how to set the inputs to the model, and the model has to explain to the User how to use the outputs of the model. 5. The User decides how he wants the outputs of the model to be used. In order for the User to be able to do this: 1. IBIS is responsible for setting a standard for Model Makers to define the capabilities, inputs and outputs of their models. 2. The Model Maker is responsible defining the capabilities, inputs and outputs of his model, and to do that according to the standard set by IBIS. The Model Owner's Manual needs to explain to the User what the models can do, what assumptions it is making about its operating environment, what its inputs are and what its outputs are. The Model Owner's Manual has to explain to the User how to set the inputs to the model. 3. The EDA Tool is responsible for enabling the User to implement how the User wants to do an analysis and how the user wants to use the outputs of an analysis,. This applies to AMI Models, IBIS Models, ISS Models, Verilog Models, VHDL Models. I do not know how it can be any other way.
