PARSER VERSION NUMBER: 5.0.3

PLATFORM (SPARC, HP700, PC, etc.): PC

OS AND VERSION: Windows 2000

REPORTED BY: Bob Ross, Teraspeed Consulting Group

DATE: July 27, 2010

DESCRIPTION OF BUG:

There is no indication when a [Model Selector] in a file is not used.

The recommendation is to issue a Caution message for unused
[Model Selector]s because they may indicate unintended pin assignment
or extra [Model Selector]s that were intended to be removed.

The test case reports illustrates a file that passes the ibischk5 parser
and also contains an unused [Model Selector].  The check should be done
for [IBIS Ver] 3.2, 4.2 and 5.X files.
