Detect Out Of Bound Array Access

Check ID: mathworks.sldv.arraybounds

Detects operations that access outside the bounds of an array index

Description

This check detects instances of out of bound array access in Simulink Design Verifier.

Following the recommendations of this check increases the likelihood of generating MISRA C:2012 compliant code for embedded applications, as well as code that complies with the CERT C, CWE, ISO/IEC TS 17961 standards.

Results and Recommended Actions

Result	Recommended Action
Failed, model incompatible	Resolve the model incompatibility. See Supported and Unsupported Simulink Blocks in Simulink Design Verifier (Simulink Design Verifier) Support Limitations for Model Blocks (Simulink Design Verifier) Support Limitations of Simulink Design Verifier for Simulink Software Features (Simulink Design Verifier) Support Limitations for Stateflow Software Features (Simulink Design Verifier) Support Limitations for MATLAB for Code Generation (Simulink Design Verifier) Also see Handle Incompatibilities with Automatic Stubbing (Simulink Design Verifier).
Out of bound array access found in model	To view the conditions that cause the out of bound array access, create a harness model. When you simulate the harness, the inputs replicate the error. Click View test case in the Model Advisor report.

Capabilities and Limitations

• Does not run on library models.

• Analyzes content in masked subsystems. By default, the input parameter Look under masks is set to all.

• Analyzes content of library-linked blocks. By default, the input parameter Follow links is set to on.

• Does not support exclusions.
