Frequently Asked Questions

• What Polyspace Access does?

  Polyspace Access is a platform that lets you check your code quality throughout the software development life cycle. It’s a central place to identify coding defects, review static analysis, and monitor software quality metrics.

• Can I install Polyspace separately from MATLAB or Simulink?
  Starting from R2019a, Polyspace Bug Finder and Polyspace Code Prover are standalone products that can be installed independently of MATLAB and Simulink. However, integration with MATLAB/Simulink requires additional steps.

  To install Polyspace R2019a or later, follow these steps:

  1. Download the MathWorks Installer
  2. Launch the installer and log in to your MathWorks account when prompted.
  3. In the installer, select your “Polyspace Desktop,” “Polyspace Server,” or “Polyspace Test” license. Contact your local MATLAB license administrator if no Polyspace license is available.
  4. Follow the remaining instructions to install the Polyspace products.
• How does Polyspace help find bugs in code?

  Polyspace Bug Finder uses static analysis including semantic analysis to look at software control, data flow and interprocedural behavior. By finding defects early you can triage and fix bugs at the beginning of the development process.

• What is Polyspace Code Prover?

  Polyspace Code Prover uses static analysis and abstract interpretation based on formal methods. It can be applied to handwritten code, generated code or a combination of the two. Each operation is color coded to show if it’s free of run-time errors, proven to fail, unreachable or unproven.

• What is Polyspace Test?
  Polyspace Test provides tools to develop, manage and execute unit and integration tests for C and C++ code in embedded systems. You can create tests using the Polyspace xUnit API or a graphical editor, with stubs or mocks to isolate and verify code. Tests can run on host computers or embedded targets and be linked to requirements for traceability.

  It includes code coverage analysis (e.g., decision, condition, MC/DC) and automatic test generation for full coverage and boundary testing. The Polyspace Test comes with a common user interface which allows you to configure, run and review static analysis results to ensure test robustness. Industry standard support is available through IEC Certification Kit (ISO 26262, IEC 61508) and DO Qualification Kit (DO-178).
• How do I use Polyspace with Simulink?
  We can integrate Polyspace with MATLAB and Simulink to analyze Generated Code.

  To connect your MATLAB and Polyspace installations, follow these steps:

  1. Launch MATLAB with administrator privileges.
  2. (For versions prior to R2021a) Navigate to the directory polyspaceroot\toolbox\polyspace\pscore\pscore\, where polyspaceroot is the folder where Polyspace is installed, e.g., C:\Program Files\Polyspace\R2019a.
  3. In the MATLAB command prompt, enter: polyspacesetup(‘install’)
  4. A prompt will appear informing you that the workspace will be cleared and all open models closed. Click “Yes” to proceed. The process may take a few minutes.
  5. Restart MATLAB.
• Can Polyspace be integrated into CI/CD?
  Yes, Polyspace can be integrated with CI/CD workflows, including Jenkins and Bamboo, to automate static code analysis or dynamic testing. So you can find and fix code defects early.

  Polyspace in your CI/CD pipeline means continuous compliance to quality and safety standards, reducing the risk of runtime errors and making your software more reliable.
