First, I create a functional breakdown in a functional breakdown diagram.
I want to create a system architecture diagram for different functional level like internal block diagrams in SysML.
When I want to use the functions I created in an architecture diagram (I use manage function allocation) I can only use the functions of the lowest level of my breackdown (the mother functions containing other functions are grayed out and cannot appear in the architecture diragram), but I would also like to make architecture diagrams representing the functional exchanges of higher levels (see attached images).
The functional data flow bank diagram makes it possible to manage multi-level functional exchanges, however it is not an architecture diagram, we cannot allocate actors and entities to functions.
Do you know a solution that would meet my need?
Thank you in advance.
