All,
A test case is attached to illustrate these contradictory rules under
[Interconnect Model Group]
Page 32:
Identifiers associated with these Termimal_type *_I/Os are pin_name entries.
In addition, some *_I/O terminals may have the optional Aggressor_Only
column. If any *_I/O pin is marked as Aggressor_Only, then any *_I/O pin
with the same pin_name entry shall be considered as an aggressor, and not a
victim. Any *_I/O Terminal_type without the Aggressor_Only column may be
considered as an aggressor or a victim.
Page 33:
o No I/O pin_name in a component may appear as a Pin_I/O terminal without
the Aggressor_Only column in more than one Interconnect Model in the
Interconnect Model Group.
o No I/O pin_name in a component may appear as a Buffer_I/O terminal
without the Aggressor_Only column in more than one Interconnect Model in the
Interconnect Model Group.

The test case currently generates 32 Errors
16 Errors (these can be supressed and are contrary to the page 32 rule)
E6036 - [Interconnect Model Set] X9 [Interconnect Model] QQQ: Terminal 1 and
Terminal 2 both don't have Aggressor_Only defined though the pin_name is
same
16 Errors (only the Pad_I/O is marked Aggresssor_Only, but the [Interconnect
Model]s violate the rules on page 33)
E5908 - [Component] Fake1 [Interconnect Model Group] Y9: Pin_I/O Pin A1
appears in a terminal without the Aggressor_Only attribute in more than one
contained model in the group
E5908 - [Component] Fake1 [Interconnect Model Group] Y9: Buffer_I/O Pin A1
appears in a terminal without the Aggressor_Only attribute in more than one
contained model in the group
----
Two possible solutions to make the test case legal:
1. Contrary to the rule on page 32, require marking Aggressor_Only on
two [Interconnect Model] interfaces with the same *_/I/O pin_name, OR
2. Interpret the rules on page 33 to mean "without the Aggressor_Only
column (whether marked or unmarked)"
The Specification needs to be fixed. We can bring this up at the meetings.
