The Polyspace R2021a release from MathWorks introduced significant advancements in handling complex C/C++ projects, particularly for safety-critical and automotive industries. This version focused on speed, mixed-language support, and expanded compliance for international safety standards. Key Features & Major Updates
Mixed C/C++ Analysis: Polyspace Code Prover now supports projects containing both C and C++ source files simultaneously. By using the -lang C-CPP option, the tool compiles and verifies them as a unified C++ project, eliminating the need to separate files.
AUTOSAR Enhancements: Analysis of code using the AUTOSAR RTE API is faster and more precise. New "smart stubs" for AUTOSAR libraries allow users to check for standard compliance without losing precision or needing complex manual setups.
New "Guidelines" Checkers: Polyspace Bug Finder introduced a new category for software complexity. These customizable checkers measure metrics like cyclomatic complexity and the number of execution paths, helping developers identify and refactor overly complex modules early.
Expanded Coding Standards: Support was added for additional rules within AUTOSAR C++14, CERT C++, and MISRA C++.
Cross-Release Workflows: Users can now use Polyspace R2021a to analyze code generated in previous versions of Simulink (starting from R2020b) using the pslinkrunCrossRelease function. Usability and Integration
Compiler Support: Added official support for Visual Studio 2019 and GCC 8.x compilers.
Simplified Setup: The integration process between Polyspace and MATLAB/Simulink was streamlined to require fewer steps.
