RE: Action Item: Draft proposal for prevention of SCE-MI 1.1 and SCE-MI 2.0 model mixing

Shabtay,

The use of the term "model" is arbitrary but convenient.

The more precise definition is "some level of heirarchy containing macros
in itself or below cannot have DPI functions anywhere in itself or below".

Similarly, "some level of hierarchy containing DPI functions in itself
or below cannot have macros anywhere in itself or below.

This forces macros to only exist in disjoint hierarchies from functions.

I'm just conveniently labeling such hierarhcies as "models" because that
is how we think of them.

Hi John,

 

Can you explain the why SCE-MI 1.1 message port must be instantiated only at the highest level of the hierarchy within the model and why DPI function call is declared at the highest level of the hierarchy within the model?

 

Thanks,

 

Shabtay
