Polyspace Code Prover analyzes all code paths against all possible inputs to prove the absence of certain run-time errors such as overflow, divide by zero, and out-of-bounds array access in C/C++ code. It also provides control and data flow insights, and proves the correctness of concurrent access of global variables shared across tasks (threads).
Polyspace Code Prover uses static analysis through abstract interpretation based on formal methods, producing results without requiring program execution, code instrumentation, or test cases. Results are easy to understand and actionable: they appear inline in the source code with color-coded findings, variable range information, and code navigation. You can use Polyspace Code Prover on any combination of C/C++ code, manually written or generated from Simulink or an AI assistant.
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 certain run-time errors such as integer overflow, divide by zero, and out-of-bounds array access in C/C++ 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 files to trace data propagation, function calls, and variable ranges at each statement. Identify unreachable or redundant code and verify alignment with architectural design or ARXML specifications.
Analysis of Global Variables and Concurrent Access Patterns
Analyze global variable read and write, including pointer-based access. Identify unprotected shared data across tasks or threads, 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 overflows. Trace inputs to failing operations to model attack paths, assess exploitability, and prioritize security risk reduction.
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.
