Internal block diagram

Example IBD showing internal structure of a subsystem and the ports to other subsystems and external systems.

Internal Block Diagrams (IDD)[1]: 52  are a static representation of the internal structure of blocks. Where the BDDs represent a black box view of the system, the IBDs represent a white box view. It details how the parts of a block are interconnected through ports and connectors, providing a clear visualization of the system's internal composition and interactions.[2]
