Polyspace R2021a

For users of Model-Based Design, R2021a introduced cross-release workflows that were previously unavailable. The new pslinkrunCrossRelease function allows engineers to analyze code generated from an earlier Simulink release using a later release of Polyspace. This feature requires the Polyspace version to be newer than the Simulink version, with Simulink being R2020b or later. This forward-compatibility greatly improved the flexibility of continuous integration pipelines.

A static analysis tool is only as good as its precision. A tool that cries wolf (false positives) eventually gets ignored by developers. Polyspace R2021a introduces updated abstract interpretation algorithms that improve precision in complex control flow scenarios. polyspace r2021a

This flexibility simplifies CI/CD pipelines, allowing teams to use the latest static analysis features without immediately upgrading Simulink. or not yet reviewed.

This article explores Polyspace R2021a in exhaustive detail: its core products (Polyspace Bug Finder and Polyspace Code Prover), new features introduced in this release, integration with CI/CD pipelines, MISRA/AUTOSAR compliance, and practical workflows for ISO 26262, DO-178C, and IEC 61508 certification. new features introduced in this release

R2021a added support for (covering the latest rules for ISO C11/C18) and expanded AUTOSAR C++14 guidelines to 320+ rules. The Polyspace Metrics dashboard now includes rule coverage heatmaps, showing exactly which MISRA/AUTOSAR rules are violated, justified, or not yet reviewed.
