Functional Safety Standards

Developing products to safety standards with Model-Based Design

With MATLAB and Simulink, engineering teams speed up product development while ensuring compliance with the most rigorous requirements of safety standards such as ISO 26262, IEC 61508, EN 50128, EN 50657, IEC 62304, ISO 25119, DO-178C, and DO-254.

DO Qualification Kit and IEC Certification Kit provide reference workflows and guidance that let you meet the requirements of safety standards throughout their process models.

The kits provide guidance on methods and tool use cases, which you can use at the system, hardware, and software levels covering specification, design, implementation, verification, and validation activities. Verification and validation with Model-Based Design span activities of verifying software units to validating system requirements. With Model-Based Design simulation capabilities, you can shift left much of these verification and validation activities even before final implementation or production-intent hardware becomes available.

Concept and Development Activities at the System Level

With Model-Based Design, you can use System Composer, Simulink, Simscape, and verification and validation tools in Simulink to conceptualize, specify, design, develop, verify, and validate your electrical and/or electronic (E/E) systems, including:

Specification of system safety and non-safety requirements
Development and specification of architectural designs with backward traceability to system requirements and forward traceability to individual disciplines (hardware and software)
Early verification and validation of system requirements and system designs
System rapid prototyping (4:50) and system-level hardware-in-the-loop testing

Working with your requirements and architectural design within the same environment.

Development Activities at the Software Level

Engineers develop embedded software with Model-Based Design to meet certification standards (23:33)

Specification of software safety and non-safety requirements
Development of software architecture designs with backward and forward traceability, respectively, to software requirements and software elements
Design and implementation of software units, without or with automatic code generation
Design, implementation, and integration of software components, including automated code generation from software component models
Static and dynamic verification at the software unit, software component, and fully integrated embedded software

Testing your software as soon as your detailed design models become available.

Development Activities at the Hardware Level

Model-Based Design lets engineering teams develop FPGA and ASIC applications (3:06) that comply with standard requirements on programmable logic devices, including design and verification activities.

Supporting Processes

In addition to engineering processes, Model-Based Design provides several capabilities relevant to supporting processes.
