Perform Verification and Validation Tasks in DO-254 and ISO 26262 Workflows
Certification workflows such as DO-254 and ISO 26262 are increasingly used by design teams in industries where high-integrity systems are a requirement. These workflows ensure that in each successive phase—conceptual design, detailed design, and implementation—the design is verified against the previous phase.
Using Simulink, engineers can satisfy DO-254 and ISO 26262 objectives while realizing cost and schedule benefits through early verification of requirements, model and code standards checking, code generation, and test case reuse:
- Requirements can be traced from requirements documents, though Simulink models, and down through generated HDL and testbench components.
- HDL cosimulation provides back-to-back testing of designs at the conceptual design and detailed design stages.
- FPGA-in-the-loop testing enables back-to-back testing with designs at the implementation stage.
