What Is Polyspace Code Prover?

Polyspace^® Code Prover™ helps engineering teams develop safer and more reliable embedded software by proving the absence of certain critical run-time errors in C and C++ code. Using formal methods based on abstract interpretation, it analyzes all possible inputs, control flows, and data flows to identify potential software failures such as numerical overflows, divide-by-zero, and out-of-bounds array access before deployment.

Unlike traditional testing approaches that exercise a subset of execution scenarios, Polyspace Code Prover analyzes software behavior across all possible run-time conditions represented by the code. This enables teams to detect defects early, reduce reliance on robustness testing, and gain greater confidence in software quality. Analysis results are presented through intuitive color-coded findings that help engineers quickly distinguish code proven safe from code requiring investigation.

Polyspace Code Prover also provides software architecture insights that help engineers understand and verify complex codebases. Teams can identify dead code, explore exhaustive function call graphs, analyze global variable usage, and gain visibility into multitasking behavior. These capabilities are especially valuable when maintaining legacy software, onboarding developers, or verifying that implementation aligns with architectural design.

For Model-Based Design workflows, Polyspace Code Prover integrates with Simulink^® to automate verification of generated code and maintain traceability between generated code and model-level analysis results. It supports development workflows that include user-written code, generated code, and AI-generated code.

Polyspace Code Prover also helps organizations produce verification evidence and certification artifacts for major safety and security standards, including ISO 26262 and DO-178C. Whether developing automotive, aerospace, industrial, medical, or other embedded systems, teams use Polyspace Code Prover to improve code quality, support compliance activities, reduce late-stage defects, and deliver software with greater confidence.
