It describes the 3 last slides I included: http://fi...

Re: PAR scope and direction

Interesting insight...Ian. So it appears we are describing interfaces as to how they interact and not really devices or assemblies per se as part of larger assemblies. The behavioral aspect of the assembly is not the device or assembly itself, but is the interfaces and how they interact. The provide...

Re: PAR scope and direction

Ian is right. Access mechanisms is only part of the design, but not what the provider is going to provide to the standard process. The provision is for the " conforming descriptions " as Ian stated it. The term component is also troubling to me. Component parts is slightly better. But are we not rea...

Re: PAR scope and direction

I feel there is more involved than just a behavior description of interfaces (the green braces in my diagrams). There is the aspect of the behavioral description of the transformations inside the device as well mapping the right hand side back to the left hand side (the yellow braces in my diagrams)...

Re: PAR scope and direction

to extend test access to the system level We should discuss to what we are extending access to. If "level" is left off, I believe the meaning of the sentence is too weak. What is meant then as extending access to the system? Some could argue they already have access to the system for functional tes...
