Bug Finder Analysis in Simulink

Check C/C++ code imported into and generated from Simulink® models for defects

Use Polyspace® from the Simulink Editor or the MATLAB® Command Window to identify potential bugs, runtime errors, and coding standard violations in your Simulink model. Use Polyspace in two different steps of the verification and validation process.

Before generating code, detect and address issues that might be introduced by the custom code in your model. Analyze the custom code in the C function block, the C caller block, and the S function block. See Run Polyspace Analysis on Custom Code in Simulink Models.

After code generation, analyze the generate code for code specific issues that might not be caught in the model, such as errors due to untested parts of model or incorrect code generation options. See Run Polyspace Analysis on Code Generated with Embedded Coder.

After integrating Polyspace and MATLAB, you can run a Polyspace analysis directly from the Simulink Editor, or use MATLAB scripts to automate a Polyspace analysis. See Integrate Polyspace with MATLAB and Simulink and Run Polyspace Analysis by Using MATLAB Scripts. Alternatively, generate options files from Simulink models, and use these options files to run a Polyspace analysis on the generated code in the system command line. See Run Polyspace Analysis on Generated Code by Using Packaged Options Files.

Functions

polyspacesetupIntegrate Polyspace installation with Simulink
pslinkrunCrossReleaseAnalyze C/C++ code generated by R2020b or newer Embedded Coder versions by using a different version of Polyspace that is more recent than the Simulink version (Since R2021a)
