The subject of my PhD study is the transformation of the output of CAD
systems to a model that can be used for model-based diagnosis.
In a model suitable for MBD the behavior of the system to be diagnosed
must be described in terms of the units that are to be replaced
(e.g., the Field Replaceable Units). Information from CAD systems may
or may not contain such information; I am curious to know how
difficult my work will be, or even if it is impossible.
I am currently investigating two standard languages for information
interchange between CAD systems: EDIF and VHDL (VHDL is more than
that, I know). I know that in both languages the information that I
need CAN be given, but more interesting for me right now is: Is it
actually provided.
I would like to ask you, as users of VHDL, some questions, so that I
at least know if I am pursuing the impossible:
1. Is VHDL mainly used for VLSI devices, or could I also expect to get
VHDL descriptions for PCB's, or even whole systems?
2. If I get a VHDL description of a system, can I recognize the
physical hierarchical construction of the system, like:
- the system's behavior is described in terms of the behavior of
PCB's of parts of PCB's
- the behavior of PCB's is described in terms of the behavior of
the components on the PCB's.
To any kind souls willing to answer: thanks in advance.
