ISO/TS 10303-1637:2006 specifies the application module for Assembly module macro definition.

ISO/TS 10303-1637:2006 deals with the representation of predefined subsets of a design for reuse functionality. The assembly macro definition is supported by an equivalent capability in the context of interconnect substrate design reuse. The expected usage of this capability is only in the context of library stored design data and in design system to design system data sharing and exchange. A macro is not intended to be a directly realizeable design definition. The essential feature of ISO/TS 10303-1637:2006 is the inclusion of terminals that only exist in a macro definition so to support their reference in floor planning based design and their subsumption and replacement upon macro expansion in the detailed design. In ISO/TS 10303-1637:2006, assembly macros rely on interconnect macros for connectivity implementation.

The following are within the scope of ISO/TS 10303-1637:2006:

• terminals of assembly module macro;
• assignment of interconnect macro component terminals to assembly module macro terminals.
