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.
