Re: Model name question

Arpad,

I believe many simulator vendors already identify models
internally by the following tuple:

(component_name, model_name)

I would recommend formalizing this in future IBIS specifications.
We need not specify the exact format of the naming convention,
but we do need to clarify that a model should be identified by
component_name and model_name, since model_names are
not unique.

If we were all real sticklers, we would require tools to identify
a model by the following tuple:

(component_name, model_name, revision)

Many a time I have been bit by multiple revisions of models laying
around ... especially with automatic path searches of model directories,
where the last model loaded is the one that is used.

regards,

scott
