SUB SYSTEM DESIGNER PORTABLE
The example describes the Portable Audio Player's composition, detailing how each of the subsystems is structured. The Portable Audio Player's composition is described in greater detail in the Portable Audio Player's Internal Block diagram: In this example, the Portable Audio Player is defined in SysML as a system composed of subsystems that perform specific tasks the design shows subsystems for supplying power, performing playback and audio processing, and interfacing with other devices and the user interface. This diagram shows an example Design Model for a Portable Audio Player the SysML Block Definition diagram describes the Portable Audio Player as a composition of various reusable off-the-shelf subsystems and in-house designed ones. the sub-systems making up a system and the framework for sub- system control and communication is called architectural design. The SysML Design Model contains the Blocks that define the system's composition it describes the manner in which reusable subsystems fit together to fulfill the design requirements. The subsystems can also be linked back to the requirements they are implementing, and then to the stakeholders who own the requirements. 6Subsystem Design Highlights: Pipelines and data. sensors.Buses and networks-on-chips.Standards for IP. Subsystems can be hyper-linked to more detailed diagrams, which allow the viewer to click through from the system level through to all its constituent parts. Systems are typically complex and must be broken down into a number of subsystems that will interact with each other through known and published interfaces.Ī Block Definition diagram can be created in Enterprise Architect to model the decomposition of a system into a hierarchy of subsystems. Once the requirements have been elicited, modeled and analyzed, the attention of the engineer turns to design. Team Vision for Subsystem-Level Design Phase Goals. Overall the goal of this phase is to create, choose, and come up with specific ideas for sections of the system. The SysML systems engineering modeling language has a strong focus on design. The subsystem design phase is a smaller section of the overall detail design phase.
