Hi Erin ,

Current calculated is nothing but the Voltage drived at the driver end =
to
the impedence seen by the driver at the same end. For current at load =
side,
the same thing applicable. i.e. voltage sensed by the load to the =
impedence
seen by the load. Basically, Current gives idea about logic level. =
Polarity
of the current shows the sink/source.For further help refer Hyperlynx =
guide.

Subject: [SI-LIST] Hyperlynx Results interpretation

Hi
I had a couple of questions of interpreting the results from Hyperlynx =
if
any of the experts out their may know the answer or point me to the =
answer.

1.  Does Hyperlynx simulate the ESD protection diodes through the =
ground/vcc
clamp parameter in the IBIS model or is it omitted to show real levels =
in
the trace.  I ask this, because if they do then the levels of
overshoot/undershoot would likely be higher and other ICs could be =
buffering
other parts by clamping the waveform before it exceeds their min/max
specification.

2.  Using the oscilloscope in Hyperlynx they give the current waveform =
in
the CSV output file.  Is this the current measured in the trace =
connecting
to the driver, or is it the current that is actually entering the =
protection
diodes/parasitic capacitance of the part?

Sorry, if this questions seem trivial.  I want to make sure that when I =
see
overshoot/undershoot that I correctly interpret the levels to make
recommendations.

Any other information on interpreting/using Hyperlynx for SI application
would be greatly appreciated.
