Michael Mirmak convened the meeting.  No patents were declared.   

Walter Katz moved to approve the minutes of the June 24 meeting.  Bob 
Ross seconded.  No objections were raised and the minutes were approved.

During Opens, Walter noted that he had sent out a list of suggested 
Vtable equations via the reflector (shown as alterations to p. 53).  
Michael asked Mike LaBonte to check whether this change is already part 
of the edits list; it is.  Bob agreed with Walter on the change content.
Arpad Muranyi asked what is meant by “source” term in the revised language.  
The specific wording will be discussed later.  Mike noted that the new 
Pin Referencing BIRD addresses some of this.  The team seems to have lost 
interest in definitions.

Mike proposed reviewing the new I-V table text.  Walter summarized his 
changes, which primarily are dedicated to describing the reference 
terminals correctly, *globally* (except for External Model).  

Vtable is the lookup into the voltage-controlled current source. It gets 
rid of Vcc-relative as a concept.  Walter deferred to Bob for how ECL 
should be described.  On ECL, Bob suggests replacing Vcc with Pulldown_ref; 
the other ECL rule is replace Pullup_ref with Pulldown_ref.   Bob noted 
that ECL technology needs to be defined precisely in the specification.

Bob noted that [Voltage Range] or [Pullup Reference] are mentioned; the 
same pair or option should be noted for [Pulldown Reference] in the new text.
Michael suggested an alternative notation based on SPICE probing: V(node, node), 
where both nodes of the measurement are explicit.  This avoids problems with 
implications of voltage “at” nodes and makes the values for the equations clear.  
Arpad agreed.  Mike suggested that a terminal name be added.  Randy will be 
showing some diagrams soon for multi-element C_comp where the terminal name 
for measurement is listed.  

Walter notes that ideal node zero is present in all three nodes in actual 
equations; this cancels, so the equations are correct.  Michael agreed, and 
would prefer both notations appear at least once, with an explanation of the 
extra reference node.  

Arpad noted an inconsistency: V-t tables for the Pullup should have been 
measured from pad to Vcc-rail; instead, V-t tables are measured relative to 
pulldown, etc. rail.

Walter proposed that Pullup_ref be used as language for both node and voltage.  

Arpad suggested that this might mix up voltage and node concepts for users.  
Walter agreed, and suggested that V(Pullup_ref) is the voltage at that terminal 
with respect to some other terminal.  Just think of it as the node. 

A brief discussion on nodes vs. terminals was conducted. These are the same 
thing, as agreed by Walter and Arpad.

Mike observed that the left side of equation is currently “Vtable” – the term 
“voltage” is being used explicitly.  Voltages in the data tables are correct, 
per Walter; Mike notes that this column is called “Voltage”.
Mike noted that he cannot post Draft 3 as only a draft 1 was ever distributed.  
Mike accepted an AR to send out the reference Pullup_ref document and Mike and 
Bob will edit it offline.  

Walter proposed that Draft 1 be reviewed offline, then that the team assess the 
comments during the meeting.  This comment resolution approach is much more 
efficient when used by other groups.

Randy Wolff moved to adjourn.  Mike seconded the motion.  The meeting adjourned.
