Often, an IBIS file comes with one example pin (in
[Pin] section) for each I/O buffer model.
The user then creates their own [PIN] section
following the example.
As Craig notes, there are tools that can
automatically generate [Pin] section from
component info.
Also, you might check with your apps engineer to
see why this dml feature is not working as expected.
Cheers,
Lynne
