Hello Fellow IBISans, Paul and Ron:
Much progress has been made and nearly all of the PACKAGE problems are
fixed. Four issues are listed below:
(1) One crash related to [Number of Pins] missing data has been fixed.
Another crash occurs if the entry is incorrectly given as "1" (several
other numbers may also produce a crash). You get "mtx.c323: assertion
failed. Abnormal program termination." I get similar results on DOS.
Also, I got a Segmentation fault on a Unix system in one case. So there
are problem still some pointer problems which will lead to crashes.
(2) For "Banded_matrix" choices, the Specification states that the last
row entries contain successively fewer columns. The parser operates
successfully, but I believe the Specification is wrong.
(3) For "Sparse_matrix" choices, some problem are related to not accepting
alpha-numeric indicies in the "Index" column of the Row data line.
(4) There is an omission in the Specification regarding the correlation
of actual [Pin] entries and number of entries with those required in
[Pin Numbers].
Attached at the end is an IBIS file illustrating these points.
Otherwise, the IBISCHK2 works well at testing the major features at a very
robust level, and is converging on handling the Version 2.1 package model
extensions very well. This is required for dealing with any extensions such
as those of BIRD28.
Good Work Ron and Paul!
