All,
I agree with Walter’s suggestion of removing all that stuff from this BIRD.
There is no
need to over complicate this with package modeling related features when this
BIRD
started out as a buffer model improvement proposal. The package improvements
are
addressed in BIRD189 already, there is no need to introduce yet another way to
write
package models for IBIS.
To summarize, the TS4file is strictly a replacement for [Model]. If the .ibs
file has only
legacy package models, the buffer model is connected to the pad, but if the
package
model uses the new BIRD189 features and defines an on-die interconnect, than the
TS4file is connected to the “buffer terminal” (not the pad). Walter, is this
what you
intended with this latest change?
Thanks,
Arpad

All,
I am including BIRD158.6 draft3 with all existing changes accepted, and my
recommended changes which are to remove all reference to terminals at pad or
pin.
I strongly recommend that they be at the buffer. There should not be any
package interconnect in the Ts4file (we should certainly not recommend doing
so) then the package model should not include that interconnect.
This is simple, it matches exactly how IC vendors are generating these Ts4files.

Hi All,
I attach a finished draft 3 of BIRD 158.6 as shown and discussed at today’s ATM
meeting. Please review it before next Tuesday’s ATM meeting for (hopefully)
final discussion and deciding on the recommendation to the IBIS Open Forum.
Mike, could you please post it at the ATM archive site.
Thanks,
Radek
