Call for opens:
 - Michael asked to discuss ibischk parser distibution
 

AR review:

New ARs:
 - Lance will check with Tammy to see if they have a current list of licensees.
   no report

Discussion:
 - Michael discussed with Pete Pupalaikisat DesignCon getting free access to 
   the parser, not just the checker, tschk. The parser is available to those 
   who have purchased the license to the source code. The user would like to 
   have an open-source parser to Touchstone 2. Michael had an AR from the 
   interconnect task group to ask this group about the possibility of 
   providing some sort of parsed data from a Touchstone 2 file. The other 
   aspect of this is the license agreement for the parser source code. At some 
   point, providing the parsed data gives away part of the benefit of the 
   source code. In summary, the problem is not technical, but financial. 
 
 - Atul delivered the source code for tschk210 with the test suite. The 
   program is compiled only for Linux. All of us work on Windows, so testing 
   is not straightforward. The group reviewed and discussed the process of 
   running the test suite. Each member of the group will investigate access to 
   a Linux machine to run the tests.
 
 - Arpad Muranyi showed a potential bug in the ibischk program. the checker
   reported a warning in the ISSO pulldown curve. The file being tested has 
   inconsistent data in the min case but not the typ and max cases. The 
   checker does not report the error. The HyperLynx checker reports this as an 
   error, but the committee checker reports a warning. Weston commented that 
   syntax errors that violate a rule stated in the specification are errors, 
   but data inconsistencies are warnings. Lance said that ibischk reports an 
   error if V-T to I-V data is inconsistent by more than 5%. The group needs 
   to look into the requirements of the checker to make the decision about 
   what is an error or warning is consistent in all the data checks.

Tabled topics (no discussion without motion):
 - none


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

Meeting ended: 12:59 pm ET
