Main Description
The HW design architecture is the resource architecture on design level. It contains a set of nodes appropriate for the
computational needs, communication busses connecting them, power supply, sensors and actuators and their connections.
This task defines the top-level structure of such hardware components, both with respect to type and interfaces. It may be
based on functionality, responsibility, legacy, etc. depending on engineering decisions. It moreover documents any
additional constraint, e.g. with respect to performance, in a separate work product.

Steps
Specify top-level hardware components
Given the functional design architecture, in particular its hardware functions and the communication pattern between all
types of functions, including relevant design constraints, this task specifies a number of hardware components. These
components are together able to realize the functionality specified in the FDA. |
Connect hardware components
This step adds HWConnectors between ports of interfaces of the components in the HDA. |
Identify design constraints
Design constraints that need to be posed on the overall hardware architecture, and particularly on specific hardware
components, are identified, assessed and documented in the dedicated work product. Such constraints could, for instance,
relate to performance and resources. |
