Why It Matters

Why Simulink Engineers
Switch to EverTest

01

Manual Harness Setup Wastes Time

Setting up a test harness for every Simulink subsystem manually is slow and error-prone. EverTest generates it automatically — interface definition included.

02

SIL / PIL Testing Is Too Complex

Back-to-back verification between model and C code is required by ISO 26262 — but setting it up is painful. EverTest makes it a one-click operation.

03

Compliance Reports Take Too Long

Generating audit-ready verification reports manually is a bottleneck. EverTest produces HTML reports automatically — with traceability built in.

What EverTest Does

Simulink Unit Testing —
From Harness to Compliance Report

From harness generation to compliance reports — one tool, your MATLAB environment.

EverTest verifies how your model behaves. To check that the model is built correctly in the first place — modelling guidelines, design rules, static analysis — see EverCheck, our companion tool. Clean the model with EverCheck, then verify it with EverTest.

The Safe MBD Workflow

01
Harness & Setup

Automatic Test Harness Generation

Isolate any Simulink subsystem instantly. EverTest builds the harness, defines the unit interface, and sets up MIL, SIL and PIL simulation — automatically.

Features

A fourteen-minute tour of the EverTest feature set. It opens with what ISO 26262 expects of a verification tool, then works through test harness and test-case generation, EverView export, coverage of design ranges and requirements, static analysis with EverCheck, the step-by-step debugger, closed-loop reactive testing, SIL and PIL with integrated C code, and the verification report your assessor receives.

FAQ

Frequently Asked Questions

Answers based on the EverTest product help — from harness setup to ISO 26262 qualification.

EverTest isolates any Simulink subsystem from the remainder of the model and creates a test harness that provides time sequences of input data to stimulate the unit, parameter values to test variants of functionality, expected output data for the reference behaviour, and an assessment mechanism to verify the unit behaviour. No manual setup is required.
EverTest reads the MATLAB workspace to populate parameter values when adding new test cases. It reads values from MATLAB variables and Simulink.Parameter objects. If parameters are missing or the model is not updatable, EverTest populates them with default values of zero.
EverTest provides a Clean-Up feature that supports you during interface changes. It fixes the format, dimensions, names and data types across all selected test cases, propagating modifications consistently and setting the order, colours and other formal data properties automatically.
In the EverTest specification you define which inputs, outputs and parameters will be used during simulation. Each interface entry includes: Name, Type, Data Type, Dimension, Min, Max, Unit and Description. The Interface sheet lets you define all characteristics including port order.
Direct comparison of simulated outputs and expected results is not always practical. EverTest supports relative, absolute and temporal tolerances for automated assessments. Pass-fail results are indicated by background colours: green for passed, light-green for within the tolerance band, red for failed, and grey for explicitly ignored values.
EverTest generates a Requirements Traceability Matrix that answers three questions for each requirement: where it is implemented in the design, where it is verified in the test suite, and what the verification results are. This supports impact analysis and audit evidence for ISO 26262.
Yes. The signal feedthrough feature of EverTest enables reactive testing of closed-loop models. EverTest uses the full power of Simulink and Stateflow for specifying signal generators, temporal patterns and conditions of plant models. The interface specification can be reconfigured for closed-loop simulations.
EverTest provides a one-click interface to Simulink Coverage, collecting structural test coverage for all executed test cases at both model and C code level. Both Decision Coverage (branch coverage) and Modified Condition Decision Coverage (MCDC) are supported. EverTest merges all work products into a self-contained coverage report.
EverTest performs back-to-back testing to verify numerical equivalence between a Simulink model and its associated generated C code. Testing is carried out at model level (MIL), followed by comparison tests between model and code (SIL/PIL). The result is a verification report compliant with ISO 26262 requirements.
Yes. EverTest provides a simple interface to integrate external C-code into Simulink for unit testing and coverage measurement. You can reuse your model-based test cases and retain the ability to change parameter values per test case. C-code can be debugged using Microsoft Visual Studio (SIL) or Lauterbach Trace-32 (PIL).
Yes. Test Signals (Type T) allow you to monitor any signal at any level of the model hierarchy without touching the original design. This avoids routing buried signals through multiple levels of hierarchy, preventing interface clutter and technical debt while keeping production interfaces intact.
EverTest is a qualifiable tool certified for dynamic model verification under ISO 26262 and IEC 61508. It ships with a safety manual assessed by TÜV SÜD and a Qualification Kit containing TCL 3 validation tests. You run the validation suite in your own project environment and document the results — that constitutes your tool qualification.
