Safety-Critical Software Testing: DO-178C Compliance
We provide comprehensive verification and validation (V&V) services designed to meet the most stringent airworthiness requirements. Our approach ensures that software functions as intended, even in the most demanding environments.
Our Testing Hierarchy
To meet the objectives of DO-178C, we execute a multi-layered testing strategy:
- Unit Testing (Low-Level): Verifying individual software components against their low-level requirements to ensure code precision.
- Software Integration Testing: Focusing on the inter-connectivity of software modules and their compliance with high-level requirements.
- Hardware/Software Integration Testing: Validating the software behavior within the actual target hardware environment to ensure seamless interaction.
Strategy & Execution
Our methodology is anchored by the Software Verification Plan (SVP) and the Software Verification Control Plan (SVCP). We don’t just “run tests”; we build a traceable path from requirement to result.
- Planning: Development of the SVCP to define the scope, environment, and pass/fail criteria.
- Execution: Formal test runs on target or simulated environments.
- Reporting: Generation of comprehensive Software Test Reports (STR) and lifecycle evidence required for certification.
The LDRA Advantage: Automated Excellence
We leverage our deep expertise in the LDRA tool suite to drive efficiency and accuracy in our testing pipeline.
- Automated Code Analysis: Rapidly identifying vulnerabilities and non-compliance with MISRA or CERT standards.
- Structural Coverage Analysis: Achieving Statement, Decision, and MC/DC (Modified Condition/Decision Coverage) requirements as dictated by Design Assurance Levels (DAL) A, B, and C.
- Repeatability: Automated regression testing ensures that software updates don’t introduce new defects.
Proven Track Record
For the past two years, we have maintained strategic partnerships with two leading software verification firms. This collaborative ecosystem allows us to:
- Scale testing capacity for large-scale projects.
- Provide independent peer reviews to ensure “four-eyes” compliance.
- Stay at the forefront of evolving aerospace certification trends.
