Model selector in P3041 ibis model

Hi. In the ibis model of the P3041, a model selector 'bvdd_io' is used on e.g. the local bus signals. With the 'bvdd_io' model selector you can select 1 of 4 models going from "3.3V I/O slowest slew rate" to " 3.3V I/O fastest slew rate" All four models than have their 'minimum' 'typical' and 'maximum' simulation cases according the ibis specification. As I don't see any setting to change drive strengths on the local bus, what is the relation between the slew rate model selector and the corner cases min-typ-max of the ibis file.

Sorry for delayed response

The output buffer has several options by design, but not all these options are available for user.

The only one option is available (permanently selected)

Please use option "01" - slow slew rate

Have a great day,
Alexander

Thanks for your answer.

Is this valid for all models in the ibis file which have the model selector based on slew rate ?
