[IBIS] RE: [IBIS-Users] IBISCHK4 parser updated; IBIS 4.2 now an ANSI specification

Hi experts,

is it possible that there is a bug in this latest IBISCHK4 (v4.2.1) version? 

I am checking one IBIS model and then I get a whole bunch of warnings that I can't explain, like:
"WARNING - Pin B1 is not defined as a Diff Pin though the associated Model Selector INOUT was determined to be Differential"

When is one pin considered to be differential? I assume only in [Diff Pin] section, but now it seems that it is looking for something else .... and I don't know what ....

With old version of IBISCHK4 (v4.1.1) I get no such funny warnings.

For your convenience I have attached the outputs of both spelling checkers (parsers).

Regards,
Radovan
