PARSER VERSION NUMBER: 7.1.0

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

OS AND VERSION: Windows 10

REPORTED BY: Arpad Muranyi, Siemens EDA; Mike LaBonte, Unaffiliated; Bob Ross, Teraspeed Labs

DATE: June 5, 2022

DESCRIPTION OF BUG:

No Error is reported for a file referenced to an absolute path.  This is
documented by rule 3 in IBIS Version 7.1, pages 18-19; and illustrated in
Figure 1.

"Absolute paths - those beginning with a root name or root directory - are
not permitted in a reference to any file."

The test case involves an EMD file where a reference to an ISS file is by an
absolute path: C:\Users\bug234.iss. This file is not at or under the file from
which it is referenced. An Error should be reported.  Note, for testing
purposes in different operating systems, bug234.iss could be placed in a
subdirectory under the absolute path.

(Arpad Muranyi reported the problem; Mike LaBonte created the test case; Bob
Ross edited the material and created the bug234.txt report.)

The command line is ibischk7_64 -emd bug234.emd.
