IBIS 3.0 model

I am in the process of creating an IBIS 3.0 for our K6-2 processor.

When using ibischk3 It Gives me the following errors:
Pull down has decreasing current.
Gnd clamp has decreasing current.

Can anyone tell me what these mean? What charateristic of the data
should I look at? Is there a document that describes the error messages?
Most are self explanatory but this one stumped me.

Also is there a working IBIS 3.x model that I can use as an example?

Thanks in advance
