PARSER VERSION NUMBER:
      Found in IBISCHK3 V3.2.9  (Rechecked with IBISCHK V4.1)

      Checked on SPARC

      Solaris

REPORTED BY:
      Bob Haller SiSoft, and IBIS Quality Committee Members

DATE:
      2 Aug 2005 original report

DESCRIPTION OF BUG:
      IBIS parser is missing checks that could uncover a flawed IBIS file.
The IBIS Quality Committee proposes that a new Parser warning message be created;
The "Caution" would be created to add a class of checks to signficantly enhance the present IBIS Parser.
The new checks would be enabled with a command line switch to minimize additional spurious warnings 
for traditional IBIS model users, but will aid the model creator,reviewer and advances users with 
enhanced automatic IBIS parser checking capability.

INSERT IBIS FILE DEMONSTRATING THE BUG:

     The attached test case summarizes one of the new requirements called out in the IBIS Quality specification 
that are not adaquately checked by the 4.0.1 IBIS parser. The Attached IBIS file should be used to test 
parser conformance to this new requirement. This IQ committee believes that this check is representative opf the new category Caution.

4.2.3  {LEVEL 1}  [Model] Vinl and Vinh enclose Vmeas

  For I/O buffers Vinl and Vinh values should be below and above,
  respectively, Vmeas. Exceptions to this should be explained in a
  comment. It's uncommon.

  +++ IBISCHK NOTES +++++++++++++++++++++++++++++++++++++++++++++++++++++
  Proposal: ibischk caution message if Vmeas not between Vinh or Vinl
    in I/O models.
