******************************************************************************

PARSER VERSION NUMBER: 6.1.4 and all since 4.2.0.

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

OS AND VERSION: Windows 10

REPORTED BY: Arpad Muranyi, Mentor, a Siemens Business; Bob Ross, Teraspeed Labs

DATE: December 17, 2017

DESCRIPTION OF BUG:
Non-Inverting and Inverting should generate Error for [IBIS Ver] 5.1 and
Below.  The polarity entries were not legal before [IBIS Ver] 6.0

For ibischk5, the following Errors are reported since the Polarity column is
not legal for an [IBIS Ver] 4.2 file.

IBISCHK5 V5.1.4

Checking bug196.ibs for IBIS 4.2 Compatibility...

E0137 (line   51) - Incorrect Number of Line Items (10) For D_to_A: Expecting 9
E0137 (line   52) - Incorrect Number of Line Items (10) For D_to_A: Expecting 9

(E0222 also is reported with earlier parsers, but this false ERROR has been
fixed for ibisckh6_32 Version 6.1.4, as documented in BUG190.)

No Errors are reported for ibischk6_32 Version 6.1.4.  The E0137 should be
repored when IBIS files contain [IBIS Ver] 5.1 and below.

INSERT IBIS FILE DEMONSTRATING THE BUG:

|****************************************************************
[IBIS Ver]   4.2
| Note that the polarity column does not generate an error with
| version numbers older than v6.0, yet this feature was only
| added in version 6.0 (by BIRD160.1), so it should be flagged
| with at least a warning..
