Elements
Parts The IBD represents the internal structure of a block, and the internal components of the block are represented by parts. These parts may have a multiplicity defined, indicating the number of instances of the component that may exist in the block. Reference Properties An IBD may contain external elements that the block does not own. These are represented by rectangles with dashed borders. Ports Ports specify interaction points between parts. In an IBD, they are represented by small squares on the edges of a part. There are two types of ports: • Standard ports define provided and required interfaces. • Flow ports specify the flow of objects between parts. Connectors Connectors are lines that connect ports and represent communication paths between the parts. Information, energy, and materials flow over these connectors. == References ==
