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.

Weston
