From Quality to Compliance
Static analysis, unit testing, coverage measurement, and continuous monitoring serve two purposes simultaneously: they improve software quality and they generate compliance evidence. Defects are caught early and the codebase stays in a known, auditable state. The outputs, requirements traceability records, structural coverage data, and tool qualification evidence, satisfy what ISO 26262, DO-178C, IEC 61508, and IEC 62304 mandate.
What Standards Actually Require
While each standard has its own structure and terminology, they share a common set of expectations.
- Requirements-based testing: every test must be traceable to a specific requirement. Testing without traceability is not sufficient evidence of verification.
- Structural coverage: standards require minimum coverage levels including statement, branch, or MC/DC, depending on the safety integrity level of the software.
- Tool qualification: tools used in the verification process must themselves be qualified or certified, so that their outputs can be trusted as evidence.
- Documented evidence: results must be recorded in a form that can be reviewed, audited, and reproduced.
Bridging Quality Practice and Compliance
Static analysis for compliance
PC-lint Plus is certified to IEC 61508 (SIL 1-3), ISO 26262 (ASIL A-D), IEC 62304, and EN 50716. It checks compliance with MISRA C:2023, MISRA C++:2023, AUTOSAR C++14, CERT-C, and CWE-compatible weakness detection. Every finding is traceable and suppressible with documented justification, exactly what auditors look for.
Unit testing & coverage for compliance
VectorCAST supports requirements-based test case management, bidirectional traceability between requirements and test results, and coverage measurement in all modes required by safety standards. This includes the Industry Modes that automatically select the correct coverage criteria for a given standard and safety integrity level. Results are certified by TÜV.
Continuous quality monitoring
Squore aggregates data from across the development toolchain including static analysis results, test results, coverage metrics, and requirements coverage into a single dashboard. It enforces quality gates that prevent non-compliant code from progressing and provides trend analysis that gives teams early warning of quality deterioration.
A Practical Path to Compliance
Building verification into the development process produces better outcomes than treating it as a final-stage activity. Static analysis introduced early prevents defect classes from accumulating. Unit testing with traceability creates an evidence base that grows with the project. Continuous coverage monitoring surfaces gaps while they are still small. Each stage feeds the next, and the outputs at every stage are the same outputs that certification authorities review.
PC-lint Plus, VectorCAST, and Squore are certified to the standards they support and integrate into existing development toolchains. The compliance evidence they produce is a direct output of the engineering work, not a separate documentation effort.
