Hallo All,
I just read the quality spec once more and have a question to page 23, point
5.6.2
It talks about open drain,sink, source and the corresponding vref.
It looks as if we put open-source and open-sink together, instead of
open-drain and open-sink.
Original text :
For Open-drain models [Model] or [Model Spec] Vref must be above Vmeas, and it
is usually set to the [Pullup Reference] voltage. For Open-source and Open-sink
models Vref must be below Vmeas, and it is usually set to the [Pulldown
Reference] voltage, typically zero. For ECL models Vref must be below Vmeas,
and is usually 2 V below [Pullup Reference].
Should it not be :
For Open-drain models and Open-sink models [Model] or [Model Spec] Vref must
be above Vmeas, and it is usually set to the [Pullup Reference] voltage. For
Open-source Vref must be below Vmeas, and it is usually set to the [Pulldown
Reference] voltage, typically zero. For ECL models Vref must be below Vmeas,
and is usually 2 V below [Pullup Reference].

Subject: [ibis-quality] Test Keyword Clarification BIRD draft 2
We decided in the IBIS Quality meeting today to circulate the draft BIRD
that was discussed. This has the small changes made during the meeting.
This BIRD is a response to parser bug 104, and it mostly has to do with the
scoping of the [Test Data] and [Test Load] keywords, which is only vaguely
defined in the IBIS 5.0 spec.
