PARSER VERSION NUMBER: 7.2.1

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

OS AND VERSION: Microsoft Windows 11 Enterprise	23H2

REPORTED BY: Arpad Muranyi, Siemens EDA

DATE: April 24, 2025

TITLE: AMI Reserved Parameter Repeater_Type erroneously reported as missing

DESCRIPTION OF BUG:

The parser incorrectly issues the following error:
"ERROR - Component 'TBD': Repeater_Pin '2P' is associated with a model 'RXmodel' whose AMI Parameter file 'RX_Redriver.ami' does not have a Repeater_Type defined"
when any of the four Reserved Parameters preceeding Repeater_Type including 
AMI_Version, Init_Returns_Impulse, GetWave_Exists, or Max_Init_Aggressors are
incorrectly written as "Usage In" or "Usage InOut" instead of the
required "Usage Info".  This error message is misleading because the
Repeater_Type parameter is present (and it is written correctly).
