PARSER VERSION NUMBER: 6.1.0

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

OS AND VERSION: Linux 2.6.32-504.30.3.el6.x86_64

REPORTED BY: Mike LaBonte, Signal Integrity Software

DATE: December 17, 2015

DESCRIPTION OF BUG:

IBISCHK generates an E4689 error for IBIS 6.0 files containing a Model_type
I/0 [Model] with the Executable subparameter. The prohibition of Executable
for I/O models began with IBIS 6.1 so this error should be suppressed.
Using IBISCHK6 V6.1.0 on the supplied testcase files:

E4689 - [Algorithmic Model] Sub parameter Executable is not allowed for model
bug171 which is of type I/O

Errors  : 1

File Failed

There was no such requirement in IBIS 6.0. This was explicitly agreed upon
in the Advanced Technology Modeling Task Group teleconference held 28 April
2015.
