Hell all,
We have described the on-die-termination as follows:
4.3.14 {LEVEL 1} On-die termination modeling documented
Any IBIS models with on-die termination should be labeled as such
using comment lines. On die termination should be modeled in [Power
Clamp] and/or [GND Clamp] tables. Document the method used to embed
the termination into the clamps.
But what happens, when we have an on-die-termination, which can be non-driving
/ driving only ??
( e.g. DDR2 with ODT )
Then we need I think a submodel, because if you put it in the clamps, it will
always be there.
I just wanted to figure out, that we have to discuss about the chapter 4.3.14
tomorrow

Preliminary list of IBIS parser cautions
http://www.sisoft.com/ibis-quality/docs/caution.txt
http://www.sisoft.com/ibis-quality/docs/bugxx_caution.txt
Goal is to reviewed Bug list/template bug for submission to IBIS open forum.
Concern was raised this if the list is too long and has too many minor
issues it will take forever to get through and approved in Open forum,
not to mention implementation. It was agreed that we will prioritize and
select a candidate or two that would justify the creation of the caution
category submit that as a bugs to the parser. Discussed possible candidates
3.1.2, 4.2.13, Should overshoot be a Warning versus a caution
4.3.4 sweep ranges of IV could be good candidate because its historical artifact
and reasonable justification to open new category. ECL may have different
requirement
Team Members should review the caution list and continue discussion on reflector
AR: Mike to rewrite wording of 4.3.4 these are not consistent
