Understanding of IBIS file


I need some help with the interpretation of the IBIS file for the NS9630. Is it right that the given data only describes the possibilities of the original toshiba asic? It seems that there is no specific IBIS file for the chip which I can use directly in my simulation tool. There are four pdf files with a large list of buffer cells. But which of them describes the real pins of the NS9360?


Which version of NS9360 are you talking about?
-> http://www.digi.com/support/identifyfamily.jsp?family=88&tp=3&tp2=0

I’m talking about the 177MHz version (NS9360B-0-C177)

Once you extract http://ftp1.digi.com/support/documentation/tc280_ibis.tar you will get a set of folders which has tarballs inside…
In you extract those you will get .ibs files… wont that help?

But again its related to buffers i guess.

All the docs that you can get is available here :-

Or is this ? http://ftp1.digi.com/support/documentation/ns9360_pinout_drawing.pdf

or http://www.digi.com/support/productdetl.jsp?pid=2594&osvid=121&tp=10&tp2=0

If none of these help then you need to log a case in http://www.digi.com/support/eservice/login.jsp?p=true

Yes I can see the .ibs files. They are all listed in tables in the pdf files. Here is a part of one which describes only the input buffers. This is also given for output, clock and bidirectional buffers.

cell name file name
IBUF ibuf.ibs
IBUFD ibufd.ibs
IBUFU ibufu.ibs
IBUFN ibufn.ibs
IBUFND ibufnd.ibs
IBUFNU ibufnu.ibs
SMTC smtc.ibs
SMTCD smtcd.ibs
SMTCU smtcu.ibs

But what does it mean? Which buffer or rather .ibs file should I choose for GPIO[1] or ADDR[0] and so on?
