A Block Definition Diagram (BDD) is a static structural diagram in the Systems Modeling Language (SysML) used to define and visualize the components of a system and their relationships. It serves as a foundational element for understanding the architecture of complex systems by depicting blocks, their properties, behaviors, constraints, and interfaces. Definitions Block: A Block is a modular unit of a system represented by a rectangle with the keyword \u00abblock\u00bb. It encapsulates its contents, which include: Properties: Attributes or characteristics of the block. Behaviors: Functions or operations the block can perform, such as operations, signals, and state machines. Constraints: Limitations that define the block&#8217;s operational parameters. Blocks can represent various components, including software, hardware, mechanical parts, and even &#8220;wetware&#8221; such as people or organizations. They support both Provided Interfaces (which the blo"}
