Complete Certification Software for Real-World Systems

Connext Cert is a software framework, based on the DDS standard, that enables system architects to build open and modular, safety-critical and real-world systems. Connext Cert can:

  • Simplify application logic and eliminate the need for custom networking code through powerful run-time libraries that provide publish/subscribe communication APIs.
  • Eliminate tens of thousands of lines of application software code and the need to generate accompanying certification artifacts.
  • Reduce the time, cost and risk of device and system-level certification.
  • Provide reusable certification evidence: A baseline for other industry-specific functional safety standards including IEC 61508 (industrial), IEC 60601/IEC 62304 (medical devices),  DO-178C (avionics), and ISO 26262 (automotive).

Supports Cost-Avoidance Initiatives

Connext Cert can save tens of thousands of lines of application software code and millions of dollars in associated integration costs. It aligns with industry-leading open architecture initiatives including FACETM, UCS and OMS.

Highest Safety Certification

The only off-the-shelf connectivity framework certifiable to the DO-178C DAL A certification standard and supporting pathways to ISO 26262 ASIL D and IEC 61508 SIL 3.

Reduces Code and Costs

Commercially-supported infrastructure that reduces custom communication and integration code, and the need to generate accompanying certification artifacts, slashing development time and expense. 

Supports Constrained Systems

Ideally suited for autonomous and distributed environments with challenging Size, Weight and Power (SWaP) constraints, such as Integrated Modular Avionics (IMA). Highly portable across safety-critical operating systems and CPUs, including those that support POSIX or ARINC 653.

Compliant with DDS Standard

A standards-based solution, compliant with the DDS programming interface and RTPS wire interoperability protocol. Interoperates peer-to-peer across DDS implementations.
