ISO/TS 10303-1676:2018-11 specifies the application module for
Functional decomposition to design.

The following are within the scope of
ISO/TS 10303-1676:2018-11:

the
representation of the information needed to describe the assignment of a functional unit in a hierarchical
network definition to an element in the physical design definition.
Usually, this information is provided by a packaging application.

the pin mapping between the functional view and the packaged view that is normally
stored in a library and which the packaging application traverses during execution.

• identification of swapping of the allocation of functional unit to a physical design component with a different allocation;
• identification of swapping of the allocation of terminals of a functional unit to a physical design component with a different
  allocation.
