[IBIS] Differential Buffer Modelling

IBIS Gurus,

 

I have some questions about generating differential buffer model as
stated in latest Cookbook 4.0.

1)          My normalized differential mode current has a similar plot
as shown in Pg 36. It's a function of the differential voltage, so that
makes the usage of keyword [Series Current] appropriate in this case. To
fill the I-V table, am I supposed to use the Vdiff vs Idiff ?

2)          For the V-T table data extraction, it was mentioned in Pg 40
that for [Series Current] keyword, PWL current source can be used to
replace the R value. What should be the PWL response to represent the
Idiff? (Idiff was only found to be a function of Vdiff from I-V
extraction). 

 

Please advise if my assumptions are incorrect.  

 

Thanks

Kong-Yew
