Todd,
Regarding: “What do you expect that string will look like?”,
I would expect that string to look the same as the
string that was set into the DLL (since you said
it echoes back the received parameters):
(My_RX_DLL(dfe(taps(1 0)(2 0)(3 0)(4 0)(5 0)))
But I don’t see how going through this exercise
answers the question we are discussing…

Arpad,
Sorry for the delay in reply – today’s errands ran longer than I anticipated.
I suggest we go through the tap example front to back and then see how that
compares to other cases.
The .ami file for a hypothetical RX declares the following:
(My_RX_DLL
(Reserved Parameters
…
)
(Model _Specific
(dfe
(taps
(1 (Usage InOut)(Range 0 -1.0 1.0)(Type Tap)
(Default 0)(Description "First DFE tap."))
(2 (Usage InOut)(Range 0 -1.0 1.0)(Type Tap)
(Default 0)(Description "Second DFE tap."))
(3 (Usage InOut)(Range 0 -1.0 1.0)(Type Tap)
(Default 0)(Description "Third DFE tap."))
(4 (Usage InOut)(Range 0 -1.0 1.0)(Type Tap)
(Default 0)(Description "Fourth DFE tap."))
)
)
)
Let’s say the .dll is called with the default settings for the tap parameters,
which gives an AMI_parameters_in string of:
(My_RX_DLL(dfe(taps(1 0)(2 0)(3 0)(4 0)(5 0)))
Let’s also say the .dll echoes back the control parameters it finds during the
AMI_Init call, using the AMI_parameters_out interface. What do you expect that
string will look like?
Todd.

about Model Specific parameters
Todd,
This was exactly my point. On what bases would an EDA tool
be expected to plot Type Tap and none of the other Types?
Or, are we saying that the tool is expected to plot any Usage
InOut/Out regardless of its Type? And could any other
expectations from the tool arise for the other Types,
depending on what their meaning is? This is where the
spec is clear as mud.
If we say that the tool should plot the Type Tap, because
we know the meaning of it (Tap), people could also come up
with other rationale for the other types. But these
expectations may all be very subjective, personally biased.
We can’t have such expectations and such loose ends in a
specification.
On the other hand, if we do not have such expectations, then
why would we allow to have InOut/Out for Model Specific
parameters? It just doesn’t make sense…
In my opinion the specification should mention what the tool
should or could do with these InOut/Out parameters, or
prohibit them.
Thanks,
Arpad
