Michael,
Sounds like there are two things you are trying to accomplish
a) allow an algo model to be associated with multiple pins
b) an algo model that processes data from multiple pins
First case makes associations of an algo model with multiple pins easy.
Second case seems to be device architecture specific and possibly may
involve changes to the EDA platform in addition to syntax changes that
allow specification of such a case.
I can see first case happening more often than the second case. Do you
agree?
Hemant

Subject: [ibis-macro] Questions on API proposal
Looking at the API proposal text, I have two implementation
questions:
1) Is [Algorithmic Model] below the level of [Model] in the
keyword hierarchy? In other words, can an [Algorithmic Model] only be
used with the particular [Model] that contains its definition?
I can imagine circumstances where I might want a single
[Algorithmic Model] definition to be used independently with several
different analog [Model]s (e.g., where the same engine design is used
separately to process data but for two different interfaces). Under the
current definition, I would have to re-define the [Algorithmic Model]
several times, even if identical, for individual [Model]s, even if they
are associated under [Model Selector] with a single pin.
2) On a related note, does [Algorithmic Model] not accept a text
string argument as an identifier? Again this implies that defining an
[Algorithmic Model] is explicit under [Model] but instantiating it is
implicit through the [Pin] list.
This effectively means that each [Algorithmic Model] is only
associated with a single [Model] and therefore a single [Pin]. I can
imagine -- and might be interested in creating -- cases where a block of
algorithmic code processes the results of data involving multiple analog
buffers associated with multiple pins. In this syntax, I have no way of
defining this association, at least not through [Pin], [Model] or any
argument to [Algorithmic Model]. The [Circuit Call] keyword does allow
me, by contrast, to associate a single block of code with multiple pins.
Am I missing something?
