[comp.lsi] EDIF 2 0 0 rom code data and test vectors

raymund@sci.UUCP (Raymund Galvin) (07/12/88)

Does anybody have an example of representing ROM code data in an EDIF 2 0 0 ?
After looking at the EDIF 2 0 0 spec, I guess it might look something
like this:

  (interface
    (port (array ADDRIN 4) (direction input))
    (port (array DATA 8) (direction output))
  )
  (contents
    (follow (protRef DATA)
      (table
        (entry (match (portRef ADDRIN) F F F F) (logicRef T F T F T F T F))
        (entry (match (portRef ADDRIN) F F F T) (logicRef T F T F T F T F))
        (entry (match (portRef ADDRIN) F F T F) (logicRef T F T F T F T F))
        (entry (match (portRef ADDRIN) F F T T) (logicRef T F T F T F T F))
        (tableDefault  (logicRef T F T F T F T F))
      )
    )
  )

Similarly, does anybody have an example of test vectors in EDIF format?

I have this horrible feeling, that the fragment shown above is all wrong
and that the correct way is 10X more verbose.   Any examples or feedback
will be appreciated.

Is there a mailing list somewhere concerning EDIF issues?

There is NOW an official "keeper of questions" for EDIF - Hilary Kahn at
Univ. of Manchester in the U.K. She will compare your question with prvious 
ones and supply the most up to date info available. New questions will be
send to the EDIF TC for review. This could take up to 2 months (volunteer
labor!), but you are ASSURED that you will get the SAME answer as everyone
else, and it will be extensively reviewed!

Hilary's netmail address (I haven't tried it!):

edif-support@ux.cs.man.ac.uk

Alternatively you could use US to the EDIF User Group office at:
2222 South Dobson Road
Mesa, AZ 85224

If you haven't at least sent your name then do so!

Have you heard about "EDIF world?"
