BUG NUMBER: 56
SEVERITY: [FATAL, SEVERE, MODERATE, ANNOYING, ENHANCEMENT] ENHANCEMENT
PRIORITY: [HIGH, MEDIUM, LOW] LOW
STATUS: [OPEN, CLOSED, WILL NOT FIX, NOT A BUG] CLOSED
FIXED VERSION: 3.2.8
FIXED DATE: November 20, 2001
NOTES ON BUG FIX: Classified at the April 20, 2001 IBIS Meeting.
A general fix related to issuing a Warning mesage if the
I-V table currents do not pass through 0 ma or at least
converge to 0 ma within some noise tolerance needs to be
proposed. More discussion is needed since there was
debate on the details of the problem
Resolve to fix problem at the May 11, 2001 IBIS Meeting.
The tolerance for testing a "0" value was set to 1 uV
at the June 1, 2001 IBIS Meeting.
(Corrected in response to a question from Atul Agarwal
to be 1 uA tolerence. 9/10/01).
