The ‘Internal Block Diagram’ supports three unique diagram constructs: a ‘Block,’ a ‘Port,’ and a ‘Connector.’ Each diagram construct is described in more detail below:

  • Block

    This construct is used to capture the physical components of a system. In the system model, an Asset entity with a Block label is generated to represent a ‘Block’ construct. In the diagram, this construct is represented as a rounded block containing the name of the ‘Block.’

  • Port

    This construct is used to specify the location where ‘Block’ constructs connect. In the system model, a ‘Port’ entity is generated to represent a ‘Port’ construct with the decomposes/decomposed by relationship to a block entity within or above a current level of composition.

  • Connector

    This construct is used to capture the relationships between physical components of a system.

    In the system model, a Connector entity is generated to represent a ‘Connector’ construct with a connects to relationship to each of the entities which represent the two connected constructs.

    In the diagram, this construct is represented as a solid line connecting two ‘Block’ constructs, two ‘Port’ constructs or a combination thereof and a line label containing the name of the ‘Connector.’
