Polyspace Code Prover proves the absence of overflow, divide-by-zero, out-of-bounds array access, and certain other run-time errors in C and C++ source code. It produces results without requiring program execution, code instrumentation, or test cases. Polyspace Code Prover uses static analysis and abstract interpretation based on formal methods. You can use it on handwritten code, generated code, or a combination of the two. Each operation is color-coded to indicate whether it is free of run-time errors, proven to fail, unreachable, or unproven.
Polyspace Code Prover also displays range information for variables and function return values, and can prove which variables exceed specified range limits. Results can be published to a dashboard to track quality metrics and ensure conformance with software quality objectives.
Support for industry standards is available through IEC Certification Kit (for IEC 61508 and ISO 26262) and DO Qualification Kit (for DO-178).
Formal Proof of Absence of Critical Run-Time Errors
Prove the absence of specific run-time errors (integer overflow, divide-by-zero, and out-of-bounds array access) in C/C++ by analyzing all paths and inputs without executing code. Enable early verification without tests or instrumentation. Prevent undefined behavior that can compromise robustness, safety, and security in embedded environments.
Sound Formal Methods-Based Code Verification
Perform sound static analysis using abstract interpretation to reason over all execution paths and inputs without executing code. Determine run-time error status directly in the source via color-coded annotations. Identify proven-safe behavior, definite defects, and code needing assumptions or design refinement.
Control- and Data-Flow-Based Architectural Understanding
Compute detailed control and data flow across functions and modules to trace data propagation and variable ranges at each statement. Identify unreachable or redundant code, and verify alignment with design or ARXML specifications.
Analysis of Global Variables and Concurrent Access Patterns
Analyze global variable reads and writes, including pointer-based and shared task or thread access, to expose control and data flow leading to unsafe concurrency. Identify unprotected shared data, unintended coupling between execution contexts, and concurrency risks affecting safety and security early in embedded software development.
Simulink Integration
Analyze C/C++ generated code from Embedded Coder or dSPACE TargetLink with Polyspace Code Prover directly from the Simulink environment. Trace verification results from generated code back to the originating model elements, enabling a continuous verification workflow from Model‑Based Design to production embedded code.
Formal Static Application Security Testing
Eliminate critical C/C++ security vulnerabilities by proving that memory safety and run-time failures cannot occur, including buffer overflows, invalid memory access, and numeric overflow. Trace inputs to failing operations to model attack paths, assess exploitability, and prioritize security risk reduction without depending solely on fuzz testing for deep or hard-to-reach code paths in complex systems.
Certification Support
Create artifacts needed to complete the certification process for industry standards. Certification completed by TÜV SÜD for use with IEC 61508 and ISO 26262 standards. Use reports and artifacts for DO-178C processes.
