Application module:
Packaged part white box model |

This clause specifies the information requirements for the
Packaged part white box model
application module. The information requirements are specified as the
Application Reference Model (ARM) of this application module.
NOTE 1 A graphical representation of the information
requirements is given in
Annex C.
NOTE 2 The mapping specification is specified in
5.1. It shows how
the information requirements are met by using common resources and
constructs defined or imported in the MIM schema of this application
module.
This clause defines the information requirements to which implementations shall
conform using the EXPRESS language as defined in ISO 10303-11.
The following begins the
Packaged_part_white_box_model_arm
schema and identifies the necessary external references.
NOTE 1
An electrical part is sometimes realized by installing one or more occurrences of die into a container and creating a set
of terminals attached to the die
on the inside and available for external connections on the outside of the container. See
Figure 1
for an illustration of a cutaway view of an electrical component that includes terms related to the Packaged_part Application Object.

NOTE 2
Two Packaged_part models may be exchanged with this part of ISO 10303, depending on usage.
One may support the exchange information that maps the functionality of the Electrical part to the
Bare_die,
or dies, included in the composition of the Packaged_part; and information that maps the terminals of those instances of
Bare_die to the terminals of the Packaged_part.
This mechanism provides maximum flexibility and information exchange and is characterized as a "white box" model.
This model is primarily included in the standard to support design to analysis activities.
Alternatively, one may map the functionality required directly to the Packaged_part terminals, and not populate the
Bare_die.
The alternative is simpler and is characterized as the "black box" model.
NOTE 3
The inclusion of composition elements to help compose a Packaged_part
does not cause the conversion of the Packaged_part to a design view.
