System engineering and model-based system engineering can mean different things to different groups, but most definitions share a common set of concepts, including starting from a set of system-level requirements used to drive a system decomposition and requirements allocation process. Then trade studies are performed on system architecture alternatives to produce a candidate architecture from which the design is developed and then simulated to verify the requirements are met.

This presentation shows how MATLAB^® and Simulink^® support this workflow when combined with Requirements Toolbox™ and System Composer™ by allowing users to:

• Capture, view, analyze, and manage requirements
• Develop a system architecture model from the requirements, existing Simulink models, ICDs, and externally created architectures or combinations of the above
• Examine the system architecture model using different views for different concerns
• Allocate (link) requirements to architectural components and perform coverage and change impact analysis
• Perform trade studies to compare, assess, or optimize the system architecture
• Design components specified in the system architecture model
• Simulate the system composition to verify system-level behavior
