Support Limitations for MATLAB for Code Generation
Unsupported MATLAB for Code Generation Features
Simulink® Design Verifier™ does not support the following features of the MATLAB Function block in the Simulink software and MATLAB® functions in the Stateflow® software. Avoid using these unsupported features in models that you analyze with Simulink Design Verifier.
The software does not support characters, which MATLAB for code generation allows.
The software does not support calls to external C functions, which MATLAB for code generation allows.
The software supports extrinsic functions only when they do not affect the output of a MATLAB function.
Support Limitations for MATLAB for Code Generation Library Functions
Simulink Design Verifier provides various levels of support for MATLAB for code generation library functions. The software either fully or partially supports particular functions. It does not support other functions.
If your model contains unsupported functions, you can turn on automatic stubbing, which considers the interface of the unsupported functions, but not their behavior. However, if any of the unsupported functions affect the simulation outcome, the analysis might achieve only partial results. For details about automatic stubbing, see Handle Incompatibilities with Automatic Stubbing.
To achieve 100% coverage, avoid using unsupported MATLAB library functions in models that you analyze.
The following table lists Simulink Design Verifier support for categories of library functions in code generation from MATLAB:
Software supports functions in that category, indicated by a dash (—).
Software does not support functions in that category.
Software supports the function in that category with limitations as specified.
