AR review:
 - Weston will work with Randy to make a suitable example for tschk testing.
   done. used public IBIS 7.0 Interconnect Model example from Micron.
   

New ARs:
 - Weston will look at making a more simple unified file for the readme 
   document.
 - Lance and Randy will work on posting the tschk2 code and executable to the 
   website.

Discussion:
a. TSCHK2.1.0 final approval and code release
   Atul released another version of TSCHK2. Randy did some tests on converting 
   G and H parameters. This version appears to do the correct calculations for 
   conversion between normalized and unnormalized values. The current test 
   cases are OK, but the format would be better with more significant digits. 
   The new version of tschk2 correctly prints the output Touchstone version 
   1.0 or 1.1 in the header comments of the file. For later versions, it does 
   not print that first line in the comments. Randy proposed that we release 
   the code and executables. The group agreed.
   
   The readme.html file is not updated. The group discussed suggestions for 
   updating that file. We will not wait for this file update for the code 
   release. [AR] Weston will look at making a more simple unified file for the 
   readme.
   
   [AR] Lance and Randy will work on posting the code and executable to the 
   website.
   
b. IBISCHK7 BUG247 Update
   Randy added a change to the bug report to recommend just changing the BOOL 
   name to something else in all the source code files.

c. IBISCHK7 BUG248 Draft 1 - crash ibischk IASSERT
   Code developers that commented said that they normally change the code to 
   work around IASSERT.
   
   Michael suggested that we check with more code license users to see if they 
   normally change the code a lot before linking it into their programs. Maybe 
   the code source needs an overhaul to make it more of a library.
   
   Randy asked about changing the website folder listed in the bug reports for 
   test files. Maybe the website folder structure needs to change to make it 
   more usable.
   
   this bug is classified Fatal since it crashes the program and any calling 
   program.
   
d. IBISCHK7 BUG249 Draft 1
   This bug is about a memory leak. It has an associated file (AMI) that needs 
   to be stored with the bug report. Michael added that the AMI file is valid 
   and works correctly. The parser checks it OK. When the parser is part of a 
   larger flow such as called from an application, the memory used for 
   checking is not always released.


Tabled topics (no discussion without motion):

Weston moved to adjourn. Lance seconded. Without objection, the meeting ended.
