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.
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.
Find objects in your model that cannot be activated during simulation and execution of generated code.
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.
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.
Improved Dead Logic Reporting
View possible causes for dead logic in the Results Inspector window, including short-circuiting and conditional execution
Parallel Test Case Validation
Use parallel computing to validate test cases or counterexamples
Bus Element Support
Analyze top-level models that contain In Bus Element or Out Bus Element blocks
Analyze models configured to use instance-specific parameters for referenced models
Input Range Design Error Checks
Detect input range violations for several types of Lookup Table blocks, Multiport Switch blocks, and CORDIC-configured Trigonometric Function blocks
Justify Design Errors
Create filter and justification rules for design error checks after analysis for iterative workflows
