For the system design, the physical functional model is derived from the functional logic model.
Physical functional model
The functional model includes the description of the context, the implemented functions (hierarchical, incl. diagnostic functions, safety functions, etc.) and the information flows (informal).
An informal description, application notes and customer-servicing notes are documented for each function (compare Function variants).
Description of time dependencies
In the system design, functions for example, are compiled into tasks and assigned to computing levels (scheduling tables).
With the exception of variables, MSRSW.DTD 1.1.0 does not possess any explicit means for describing time dependencies. These therefore have to be described informally for the functional description (<sw-function-desc>) or in <add-info>.
Partitioning in hardware und software
Partitioning is carried out taking resources and other secondary conditions (e.g. costs, etc.) into consideration.
Software architecture
The software architecture can be described in the MSRSW.DTD in that a <sw-function> is applied with <sw-function-class> = architecture.
Hardware architecture
Described in MSRSYS.DTD.
Test specification
Described in MSRSYS.DTD.
