PARSER VERSION NUMBER: 6.1.5

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

OS AND VERSION: ALL

REPORTED BY: Mike LaBonte, SiSoft

DATE: 7 May 2019

DESCRIPTION OF BUG:
The testcase AMI file has a negative Rx_Receiver_Sensitivity value, which
IBIS 7.0 does not prohibit. Checking it with "ibischk6_64 -ami bug204.ami"
results in:

=========================================================
IBISCHK6 V6.1.5

... Checking bug204.ami for AMI Version 6.1 Compatibility...

Errors  : 0

File Passed
=========================================================

However, Rx_Receiver_Sensitivity is used as a magnitude, and a negative
value hints at a misunderstanding about how it is used.

IBISCHK should warn for negative values, with a message such as:

Negative Rx_Receiver_Sensitivity value -0.1 should be positive,
only the magnitude is used.

INSERT IBIS FILE DEMONSTRATING THE BUG:

==> bug204.ami <==

Error message in a new V7.1 of IBIS.
