Weston,
Good catch!!! The following line:
"The EDA tool uses the voltages passed in through this parameter"
Should be:
"The EDA tool uses the voltages passed out through this parameter"

Subject: [ibis-editorial] PAM_Thresholds interpretation
All,
After Walter asked about the interpretation of the PAM_Thresholds parameter
this morning, I thought I should look into it to increase my understanding.
While the specification does not explicitly say that the string in the AMI
file must contain anything, the description and the example imply that the
string should have n-1 numbers in it. The description says, "The EDA tool
uses the voltages passed in through this parameter", which implies to me
that the string value in the AMI file should have n-1 numbers in it. Then in
the example code the string has 3 numbers in it.
(PAM_Thresholds (Usage Out) (Type String)
(Description "Thresholds for waveform and eye processing.")
(Value "0.00 0.00 0.00")
)
Maybe this needs a BIRD to clarify that the Value in the AMI file is only a
placeholder and the string value is ignored. On the other hand, the
description and the example imply that the model might use these numbers in
some way. This conflicts with the Usage Out syntax. So, either way, it seems
to be inconsistent.
Regards,
Weston
