Functional Safety resources

DDC-I is well known in the avionics certification community and for 20 years, has successfully completed numerous certification audits since the first DAL A certification of a Deos baseline in 1998. Working directly with certification authorities, they offer certification defense of all the DO-178 Software lifecycle data for all DDC-I provided DO-178 products including RTOS, tooling, BSPs, and other contracted deliverables. This includes all pre and post SOI 1-4 audit correspondence and action items required for certification. DDC-I delivers to their customers the security of knowing the certification of all purchased components is handled.

The DDC-I product customization and board support package services are based on a wealth of safety critical experience. They offer services that allow our customers a low risk solution for hardware and operating system support. They port their RTOS to customer-specific hardware platforms with full certification artifacts, and full defense of those artifacts with certification authorities. This allows their customers to focus on their application, not the hardware, and the software platform it is running on.
