EverTest verification of a Simulink model

EVERTEST · DYNAMIC VERIFICATION IN SIMULINK

MATLAB & Simulink Partner
Two tools, one workflow

Static analysis and dynamic verification

Use them together or on their own. Both run inside your existing MATLAB environment and both are qualifiable for safety-related development.

Static Model Analysis and Correction

EverCheck

Check your Simulink, Stateflow and TargetLink models against safety modelling guidelines — and correct them automatically. Cleaner models, fewer surprises downstream.

  • Automated model correction against safety guidelines
  • Exclusions stored in the model itself, by System ID (SID)
  • Verification reports with check results and justified exclusions

Dynamic Model & Code Verification

EverTest

Generate a test harness for any subsystem, define test cases in Excel, and run them across MIL, SIL and PIL. Back-to-back comparison and structural coverage, one workflow.

How it works

From your existing model to a clean, verified, review-ready unit

01
Minutes, not days

Download and install

One installer, no server, no admin project. EverCheck and EverTest run inside your existing MATLAB on Windows — download, install, activate the trial license, done.

02
Your model, not a demo

Pick one of your own units and test it as it is

Generate a test harness with EverTest for the unit exactly as it stands today — inputs, outputs, parameters and data types are detected automatically. Define your test cases in Excel and capture the current behaviour as your regression baseline. No scripting required.

03
Clean up safely

Check and correct the unit

Run EverCheck against your safety modelling guidelines. Violations are flagged and many are corrected automatically — refactor with the baseline already in place, so you are never guessing what a change did.

04
Prove nothing broke

Re-run the same tests

Execute the same test cases against the corrected unit. Passing means the clean-up preserved behaviour — the model is now clean and provably correct. Results, coverage and traceability merge into one self-contained HTML report.

05
Ready for the team

Share it for review

Generate an EverView file — the whole model as a single HTML page anyone can open in a browser, no MATLAB license needed. The unit is clean, verified and documented, so the review is about the design, not about chasing guideline findings.

The best evaluation is your own project: one unit, one afternoon, clean and verified.

When the stakes are high

Your assessor will ask. You will have the answer.

Qualification is your obligation, not ours — so we do the part we can. Every installation ships with a safety manual and a complete qualification kit: the use cases, the error conditions, the mitigations, the test evidence, and the validation tests. The effort on your side stays small.

Success story

From structured text to safety-compliant C code — in four weeks

safecubed · Industrial safety-critical application

The verification gap closed without a separate SIL toolchain

safecubed replaced a multi-step PLC Coder workflow with single-step C code generation using Embedded Coder.

The models had already been checked and corrected with EverCheck — clean and guideline-compliant before code generation started. Existing MIL test cases were reused to verify the model adaptations, and the production C code was integrated as a Simulink variant, so the same EverTest harness covered both model and code — no separate SIL toolchain.

The full transition took less than four weeks.

Frequently asked questions

EverCheck and EverTest run on Windows 10 or later with MATLAB R2018a or later — inside your existing MATLAB environment, no separate platform.
The trial runs for 14 days with all features unlocked — you get the full tools, including harness generation, MIL/SIL/PIL testing, reporting and EverView.
Yes — that's the point. Generate a harness for one of your own subsystems, run your own test cases and generate a verification report from your real project. That's the best evaluation you can do.
You need your own valid MATLAB and Simulink licenses. For structural coverage measurement, EverTest uses your Simulink Coverage license.
Both tools ship with a safety manual assessed by TÜV SÜD (TCL 3) and a qualification kit, minimizing the tool-qualification effort on your side. Read how tool qualification works →
