RE: question about monotonicity requirements

Katja,

In my opinion, there isn't a simple either/or answer to that question to
match your either/or question. My answer(s) are:

1) The spec is worded to mean the individual tables. Also, that's how
ibischk operates and reports non-monotonicity violations.

2) From a simulator stand-point, it is the sum of the curves that matters.

Subject: question about monotonicity requirements

I have a question regarding the monotonicity of the I-V-curves.
The Ibis 3.2 spec says:

Keywords: [Pulldpwn]...
To be monotonic, the I-V table must meet any of the
following 8 criteria:
1- The CURRENT axis either increases or remains constant as
the voltage axis is increased.
...

Does this apply to the [Pullup]- and [Pulldown]-curves or to the
resulting curve of [POWER Clamp] + [GND Clamp] + [Pullup/down] ?

Thanks,
Katja Koller
