PARSER VERSION NUMBER: 7.2.1

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

OS AND VERSION: Microsoft Windows 11 Enterprise

REPORTED BY: Arpad Muranyi, Siemens EDA

DATE: November 15, 2024

TITLE: Missing Repeater_Type not seen through Model Selector 

DESCRIPTION OF BUG:

The IBISCHK7 parser, version 7.2.1, does not generate an Error for a missing
AMI Reserved_Parameter Repeater_Type that should be found in an Rx .ami file
when [Repeater Pin] is found in the IBIS file. An error is flagged if the 
associated Rx Model is referenced from a [Pin] entry, but there is no error
if the associated Rx Model is referenced from a [Model Selector].
