The Internal Block Diagram (ibd) is used to describe the internal structure of a Block's compartment parts (i.e. a subordinate block of the enclosing Block) and how its parts are interconnected, and what flows across the connections. The specified flow items represent high-level internal interfaces. Interactions with external Blocks are also modelled to specify the required external interfaces.
The following ibd has all the possible symbols that can be used:
A real world example ibd is shown below:

The symbols available in ibds are:
The symbols along with their default stereotypes, referenced elements, stereotype frames and cross reference link attributes are:
