White Paper: Model-Based Systems Engineering (MBSE) and MATLAB for Embedded Systems Design

Introduction

In today's complex engineering landscape, the development of embedded systems requires a systematic and rigorous approach to ensure efficiency, quality, and maintainability. Model-Based Systems Engineering (MBSE) provides a framework for modeling and analyzing complex systems using a variety of modeling languages. MATLAB, a powerful computing environment and programming language, offers a comprehensive set of tools for MBSE and embedded systems design.

Understanding MBSE

MBSE is a systematic approach to engineering that uses models to represent a system's architecture, behavior, and requirements. By creating visual representations of the system, MBSE facilitates communication, collaboration, and decision-making among stakeholders.

Key Benefits of MBSE

  • Improved Communication: MBSE provides a common language and visual representation that can be understood by stakeholders with different backgrounds.

  • Early Error Detection: By modeling the system early in the development process, MBSE enables the identification and correction of potential issues before they become costly problems.

  • Increased Efficiency: MBSE can streamline the development process by automating tasks and reducing the need for manual documentation.

  • Enhanced Traceability: MBSE allows for better traceability between requirements, design, and implementation, ensuring that the system meets its intended objectives.

MATLAB for MBSE and Embedded Systems Design

MATLAB, a high-performance language and interactive environment for numerical computation and visualization, offers a rich set of tools for MBSE and embedded systems design. Some key features include:

  • Modeling and Simulation: MATLAB provides a variety of modeling languages, such as Simulink and Stateflow, for creating system models and simulating their behavior.

  • Code Generation: MATLAB can automatically generate code from system models, streamlining the implementation process.

  • Hardware-in-the-Loop (HIL) Simulation: MATLAB supports HIL simulation, allowing for testing embedded systems in a realistic environment before deployment.

  • Integration with Other Tools: MATLAB can be integrated with other engineering tools, such as requirements management and configuration management software.

Key Steps in Applying MBSE with MATLAB

  1. Define System Requirements: Clearly articulate the system's objectives, functions, and constraints.

  2. Create System Models: Use MATLAB's modeling tools to create system models, including block diagrams, statecharts, and sequence diagrams.

  3. Simulate and Analyze: Simulate the system's behavior to identify potential issues and evaluate its performance.

  4. Generate Code: Automatically generate code from the system models using MATLAB's code generation capabilities.

  5. Validate and Verify: Test the generated code against the original requirements to ensure it meets the system's objectives.

Commonly Used Tools

In addition to MATLAB, several other tools are commonly used in MBSE and embedded systems design:

  • Enterprise Architect: A comprehensive modeling tool that supports various modeling languages, including UML.

  • Capella: A free and open-source MBSE tool developed by the European Space Agency.

  • Cameo Systems Modeler: A commercial MBSE tool from IBM.

  • SystemC: A C++-based language for system-level modeling and simulation.

  • Verilog: A hardware description language used for modeling digital circuits.

Conclusion

MBSE and MATLAB provide a powerful combination for designing and developing complex embedded systems. By leveraging these tools, engineers can improve communication, collaboration, and efficiency, while ensuring that systems meet their intended objectives.
