Hi,
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?
Thanks
I’m talking about the 177MHz version (NS9360B-0-C177)
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?
