Polyspace R2021a: Advancing Static Code Analysis for Safety-Critical Systems

Polyspace R2021a, developed by MathWorks, introduces significant enhancements to its static analysis suite to improve the safety, security, and reliability of embedded software. This release focuses on faster analysis times, expanded coding standard support, and better integration for complex C++ and AUTOSAR projects. Key Feature Enhancements in R2021a 1. New Guidelines Checkers for Code Complexity

R2021a introduces a new category of Guidelines checkers specifically designed to manage and reduce software complexity.

Quantifiable Metrics: These checkers monitor metrics such as cyclomatic complexity and the number of execution paths.

Early Detection: By identifying complex modules early, developers can refactor code before it becomes a maintenance or safety liability.

Standard Compliance: The suite supports HIS (Hersteller Initiative Software) recommended thresholds for these complexity checkers. 2. Improved AUTOSAR Support

For automotive developers, this release significantly optimizes workflows involving the AUTOSAR standard.

Faster RTE Analysis: Polyspace Code Prover now runs faster and provides more precise results for C/C++ code utilizing the AUTOSAR RTE API.

Smart Stubs: The analysis uses "smart stubs" for AUTOSAR library functions, reducing the need for manual setup while maintaining high precision. 3. Mixed C and C++ Analysis

Polyspace Code Prover now natively supports projects containing a mix of C and C++ source files.

Seamless Compilation: The tool automatically compiles C files as C and C++ files as C++, then verifies the entire project as a unified C++ entity.

Reduced Overhead: Developers no longer need to separate these files to achieve successful compilation and verification. Product Suite Comparison What's New in Polyspace R2021a? - MATLAB & Simulink

What’s New in Polyspace R2021a? - MATLAB & Simulink - MathWorks

Polyspace R2021a is a major release of MathWorks' static code analysis suite, designed to verify the safety, security, and reliability of C and C++ embedded software. This release is notable for introducing "Polyspace as You Code" and expanding its performance capabilities for complex safety-critical systems. Key Features and Improvements in R2021a What's New in Polyspace R2021a? - MATLAB & Simulink

Polyspace R2021a represents a significant milestone in the evolution of static code analysis, specifically within the MathWorks ecosystem. As a tool designed for the formal verification of C, C++, and Ada source code, R2021a introduced critical enhancements that bridged the gap between rigorous mathematical proof and the practical needs of modern DevOps workflows. The Core Value Proposition

At its heart, Polyspace R2021a utilizes "abstract interpretation," a formal method that allows the tool to prove the absence of specific run-time errors (like overflow, divide-by-zero, or out-of-bounds access) without actually executing the code. Unlike traditional "bug hunters" that rely on heuristics to find likely errors, Polyspace provides a level of certainty—categorizing code into green (safe), red (error), gray (unreachable), and orange (unproven) zones. This exhaustive analysis is vital for safety-critical industries such as automotive (ISO 26262), aerospace (DO-178C), and medical devices. Key Innovations in R2021a

The R2021a release focused heavily on accessibility and integration. Key features included:

Polyspace Access: This release strengthened the web-based interface, allowing developers and project managers to review results without needing a local installation. This shifted the tool from a specialist’s workstation to a collaborative team environment.

Jira Integration: R2021a streamlined the remediation process by allowing users to export identified defects directly into Jira. This integrated security and quality checks into the standard project management lifecycle.

Expanded Coding Standards: The update provided enhanced support for MISRA C:2012 and AUTOSAR C++14, ensuring that code not only ran without errors but also adhered to industry-standard stylistic and safety guidelines.

Performance Improvements: This version introduced faster analysis engines and better support for incremental analysis, addressing the common criticism that formal verification is too slow for rapid development cycles. Impact on the Development Lifecycle

Polyspace R2021a moved formal verification "to the left" of the development cycle. By integrating with build systems and providing clear dashboards, it allowed teams to identify "unprovable" code segments long before they reached the integration or testing phases. This reduces the cost of fixing bugs, which increases exponentially as code moves toward production. Conclusion

Polyspace R2021a is more than just a bug finder; it is a quality assurance powerhouse. By combining the "exhaustiveness" of formal methods with the "connectedness" of modern software tools, it provides a comprehensive solution for developers who cannot afford to be wrong. It remains a definitive example of how complex mathematical analysis can be packaged into a usable, collaborative, and essential part of the software engineering toolkit.

In Polyspace R2021a, there isn't a feature to "generate a story" in a literary sense. Instead, you likely want to generate a report or "story" of your code analysis to share with stakeholders.

Here is how you can generate a professional report of your results: Generate a Report from the UI

Open Results: Load your analysis results in the Polyspace Platform.

Select Reporting: Go to the Reporting menu and click Run Report.

Choose a Template: Select from predefined templates like BugFinder or CodeMetrics. Set Format: Choose your output format (PDF, Word, or HTML). Run: Click Run to save the report to your output folder. Generate a Report via Command Line

If you are automating your workflow, use the polyspace-report-generator command: Polyspace R2021a is a release of the MathWorks

polyspace-report-generator -results-dir -format PDF -output-name Analysis_Story -results-dir: Path to your verified code results. -format: Standard formats are PDF, Word, and HTML. -output-name: Name your "story" file. 💡 Key Highlights in R2021a

Custom Templates: You can customize existing templates to include only specific "stories" like memory safety or coding standards (MISRA/AUTOSAR).

New Guidelines: R2021a introduced "Guidelines" checkers to track code complexity stories, helping you spot spaghetti code early.

Combined Results: You can now generate a single "story" that combines both Bug Finder (coding rules) and Code Prover (runtime errors) results. If you'd like, I can help you: Customize a template to show specific bug types.

Set up an automated script to generate reports after every build.

Interpret specific results like "Cyclomatic Complexity" or "Red Zones."
