Building the Digital Thread from MBD to MBSE to Meet ISO 26262 for Embedded Software

Adoption of ISO 26262 has led to the expansion of development methodology from hand code to Model-Based Design. A number of process improvements were identified to achieve traceability and thread pulling across the system engineering process, including connecting architecture models and implementation models, implementing traceability between requirements and models, and understanding model architecture’s implication on impact analysis. This presentation will provide an early overview of the solution that involves an integrated Model-Based Design-Model-Based Systems Engineering workflow, limited duplication of sources of truth, establishment of traceability and coverage with a requirement management tool, and a componentized modeling style.
