-----------------------MINUTES ---------------------------

- Review of minutes for September 23, 2003
   IBIS East Summit is October 21st.  Next meeting date should have been
Oct 7.
   Minutes approved with corrections.

- Announcements
  EIA Call for Patent Disclosure: No company declared a patent.

- AR Review
   Minutes and documents have been updated on the web site.
   IBIS East Summit IQ presentation - Bob H. will compile the existing=20
IQ documentation and bring copies of complete document. Document will=20
include pointer to IBIS Accuracy Handbook to handle correlation section.

- Opens for new items
   No new items.

- Detailed Documentation review
    Possible Errors That should be Checked
    Spice and Lab correlation

   Typ, Min, Max values: ibischk checks for numerical order.
   Item 8: should be "too few points".
   Item 9: "applies only to simulation models".  Intent is realistic
edge rate into buffer inputs.  Example would be input taken from a
chain of three inverters.  Somewhat fuller discussion of how this
impacts model accuracy would be useful.
   Move Item 9 to the bottom as guidance, rather than checklist item.
Or perhaps in a section on "what you need to know before simulating".
This is a model maker item, rather thsn something the user can check.
   Item 10: Any V-t table delay not due to the buffer itself should
be removed.
   IBIS 4.0 notes that V-t tables need to be aligned relative to the
same time reference.     If V-t data collection starts after N clock
cycles, then N*period can be subtracted directly from the V-t table
time.
   User check: is the total time of rising waveform + falling
waveform should be less than the maximum cycle period of the buffer.
Could note that different simulators can treat leading and trailing
dead time differently.
   Item 12 was removed.
   Item 13: replace TTL with Open Sink (Open Source) model, include
importance of using typ/min/max standard loads.
   Item 14: Sometimes [Ramp] gives better correlation than V-t tables.
Defer discussion to next meeting.

- Plans for next meeting
   Continue review of this document.
