Simulink Design Verifier

 

Simulink Design Verifier

Identify design errors, prove requirements compliance, and generate tests

Simulink Design Verifier™ uses formal methods to identify hidden design errors in models. It detects blocks in the model that result in integer overflow, dead logic, array access violations, and division by zero. It can formally verify that the design meets functional requirements. For each design error or requirements violation, it generates a simulation test case for debugging.

Simulink Design Verifier generates test cases for model coverage and custom objectives to extend existing requirements-based test cases. These test cases drive your model to satisfy condition, decision, modified condition/decision (MCDC), and custom coverage objectives. In addition to coverage objectives, you can specify custom test objectives to automatically generate requirements-based test cases.

Support for industry standards is available through IEC Certification Kit (for IEC 61508 and ISO 26262) and DO Qualification Kit (for DO-178).

Design Error Detection

Discover design errors in your model before simulation, including run-time errors, diagnostic errors, and dead logic.

Run-Time and Diagnostic Errors

Before you run simulations, you can detect run-time and modeling errors, including integer overflow, division by zero, array out of bounds, subnormal values, and floating-point errors as well as data validity errors. 

Dead Logic

Find objects in your model that cannot be activated during simulation and execution of generated code.

Viewing dead logic in your models.

Test Case Generation

Generate test cases for dynamic simulation to achieve structural and functional coverage goals.

Test Cases to Increase Coverage

Augment and extend existing manually created test cases to address incomplete model coverage.

Requirements-Based Test Cases

Generate test cases from models of system requirements.

Test Cases for C/C++ Code

Generate test cases to increase coverage of generated code and C/C++ code called from Simulink® blocks and in Stateflow® charts.

Generating tests for models that call C code.

Requirements-Based Verification

Verify formal requirements expressed using MATLAB, Simulink, and Stateflow.

Safety Requirements

Verify that your design behaves according to formally defined safety requirements that you express using MATLAB®, Simulink, and Stateflow.

Express requirements using Simulink.

Simplification of Variant Models

Use the Variant Reducer to generate a reduced model for a subset of valid configurations.

Simplify Models for Deployment

After you have fully validated your master variants model, use Variant Reducer to generate a reduced model for a subset of valid configurations. All related files and variable dependencies are also reduced. The reduced artifacts are packaged in a separate folder to enable easy deployment and sharing with customers and partners.
