Broken Promises Training The V-Model Walking the V Tool Qualification ✉ support@everbits.com

The Safe MBD Workflow —
The ISO 26262 Way

Your model compiles. Can you ship it?

We follow Part 6 from architectural design to integration. You get a clear workflow, the right work products, and evidence that walks any audit.

Three Promises MBD Breaks —
Without a Plan

01

"One Source of Truth"

The model and the generated code can disagree. Without back-to-back testing, you have two sources, not one.

02

"Faster Iteration"

Catching bugs at integration takes ten times longer than catching them at the model. Slow tests at the model mean slow shipping.

03

"Higher Quality"

A model with no enforced guidelines and no coverage targets is just a different way of writing buggy code.

No Tool Replaces a Trained Engineer.

Combining Simulink, Stateflow and ISO 26262 well is a skill — and our four professional courses give engineers a shared vocabulary for safe model-based development.

One V. Three Tools.
Every Stage Covered.

Read the standard left to right. Every clause is a stage. Every stage has a tool.

From Model Prototype to Production

Four Stages, Four Clauses,
One Continuous Workflow

Each stage has clear inputs, clear outputs, and the right tools for the job.

7CL.
Stage 1 · Architectural Design · Left arm

The model becomes the specification.

Clause 7 wants an architecture that is verifiable, configurable and testable. In an MBD project, that architecture is a Simulink and Stateflow model.

EverCheck makes sure it's a model a reviewer can trust. Every signal has a name, a type, a range, a unit. The hardware-software interface is fully defined.

Every requirement ID is annotated in a format the tool can check automatically. No traceability spreadsheets, no review-by-eye.

8CL.
Stage 2 · Unit Design & Implementation · Left arm

Where guidelines turn models into code.

Clause 8 lists ten design principles for software units. Most of them are about model hygiene: one entry/exit, no dynamic objects, no implicit type conversions.

EverCheck enforces them. MAAB and MISRA SLSF rule sets out of the box, project-specific extensions on top. The Run & Fix feature corrects the violations that have a known fix and flags the rest before the developer compiles.

The result: a well-defined subset of Simulink and Stateflow that simplifies every later step — code generation, structural coverage, formal inspection.

9CL.
Stage 3 · Unit Verification · Right arm

100% coverage for requirements & structure.

Clause 9 sets one bar: every requirement exercised, every branch covered. EverTest is built around that bar.

Test cases are organised by requirement ID. The HTML verification report combines test results, traceability, statement, branch and MCDC coverage. The same test runs unchanged across MIL, SIL and PIL — the algorithm proven in simulation is proven again on the target.

EverTest also brings Test-Driven Development into reach. Engineers write the failing test, build the feature, watch it pass. The Clause 9 evidence becomes a side-effect of the design loop.

10CL.
Stage 4 · Integration & Verification · Right arm

Does the whole behave like the parts?

Clause 10 asks the harder question: do the verified units behave correctly when wired together, on the target, against the architectural design?

EverTest treats subsystems as atomic. It generates harnesses, warns when boundaries are missing, and supports fault injection to exercise the architectural safety mechanisms.

For the back-to-back test, the same EverTest cases run on model, SIL and PIL. Numerical equivalence becomes a report, not a manual exercise.

Stage 5 · Verification Reviews · Across the V

Review the model in a browser. Anywhere.

EverView turns any Simulink or Stateflow model into a single self-contained HTML file. One click in version control, one second to open.

No licence. No setup. Anyone with access opens the file in a browser.

Reviewers navigate, inspect functionality, search for text patterns and add comments. Each set of comments saves to its own file; EverView merges them back. The author keeps authorship. The reviewer keeps independence. The audit trail keeps both.

Figure 3The verification review workflow.

A continuous workflow — from the first model to the last review. One toolchain. One audit trail.

Qualified Tools — Because the Audit Will Ask.

A clean workflow is not enough on its own. ISO 26262-8 Clause 11 requires you to demonstrate that the tools you used to produce the safety case are themselves trustworthy.

Both EverCheck and EverTest are TCL 3 qualified. Each ships with a Safety Manual, a Qualification Kit and a validation test suite that you run in your own environment.
