Kukai,
I believe that IBIS iv-vt curves are specifically mutually exclusive with
External Model. You can have only one or the other, not both in one model.

in conjunction with i-v, v-t tables)
Hi Arpad,
Apologies for late feedback as I made entry into this forum recently.
We have cases where AMI model (c-code) is supposed to work with
s-parameters for the buffer (say RDL of the buffer)
Can we extend the scope of this BIRD (or introduce New one) that covers
all cases:
1) AMI model + Analog buffer represented as Spice-IO
### Current BIRD116 would allow this
2) AMI model + VI-VT Analog buffer + RDL (etc) as parasitics in [External
Model]
### Here the External Model needs to work in conjunction with IBIS
v-i, v-t data
3) AMI model (contains Analog-IO buffer coded in AMI itself) +
S-parameter/Spice RDL
### Here the External Model needs to work w/o IBIS i-v, v-t data
Let me know if I missed fine points of the BIRD and that the cases 2) and
3) are already covered
