Hi IBIS experts, I have a question considering using [Pin Mapping] for input models. Question would be: how many entries should be for input buffer in for [Pin Mapping] keyword? Specification says: "Each line must contain either three, five or six entries." (Btw., in specification there is no example for input buffer) Format of command is: [Pin Mapping] pulldown_ref pullup_ref gnd_clamp_ref power_clamp_ref ext_ref So if I write for example: A1 GND VCC There are only 3 entries, but according to format specification second and third entry are used for pulldown reference and pullup reference respective, what is a nonsense in this case, because input buffers have only power and ground clamps and no pull-up and pull down references. If I write something like: A1 NC NC GND VCC This according to my opinion makes more sense, but still I have to use NC for pull-up and pull down references. What I was able to find as an example on Internet had always 5 entries, like: A1 GND VCC GND VCC For me this is senseless, because, as said before, one input buffer has only power and ground clamps. So, can somebody write me what is a proper format for input buffer in [Pin Mapping] ?
