******************* IBIS ICM GOLDEN PARSER BUG REPORT FORM *******************
******************************************************************************

PARSER VERSION NUMBER: 1.1.2

PLATFORM (SPARC, HP700, PC, etc.): IA32

OS AND VERSION: MS windows

REPORTED BY: Michael Mirmak, Intel Corp.

DATE: April 18, 2007

DESCRIPTION OF BUG:

The ICMCHK1 parser returns an error message about malformed filenames for
Touchstone S-parameter files with extensions of the form "snp" if n is 
greater than 9 (e.g, s14p).  No messages are returned for extensions where
n is less than 10.  

Section 8 of the ICM specification, under "[ICM S-parameter]" provides no
requirements or restrictions on the filename or extension used for the
Touchstone file.  The accompanying example clearly states "any name
and extension allowed" next to the filename used in the example.  Further,
the Touchstone specification does not require filename extensions to reflect
the actual number of ports in the file. 

This error behavior should be removed from the parser.

An additional recommendation for the specification would be to add text that
explicitly permits any filename or extension to be used for Touchstone
files linked through [ICM S-parameter].

Note that, for the enclosed example, two S-parameter files using the given
names should be present in the same subdirectory to prevent the return of
additional errors beyond those mentioned here.
