Speeding Up Design Verification Testing of VPX Systems

Today’s aerospace and defense programs are increasingly dependent on Commercial Off the Shelf (COTS) solutions. These serve as key foundation elements for a variety of Line Replaceable Units (LRUs) and complex systems in land, air and sea platforms. System integrators worldwide rely on COTS-based technology such as single board computers (SBCs) to provide key functionality for everything from graphics processing, motion control, and fire control systems to full mission computers. With pre-integrated COTS technology, integrators can design and build tailored systems for a variety of applications, quickly and cost-effectively without having to deal with hardware interoperability issues.
However, getting through Design Verification Testing (DVT) is one of the biggest challenges system integrators face as they need to ensure COTS-based boards will work as intended in a specific design configuration. Typically, COTS board-level products are not delivered with system integration support tools that are needed to speed the integration process. As a result, integrators must spend significant time developing and executing test software to properly integrate any COTS board into a system. The additional time spent trying to overcome hardware integration challenges takes time and money away from integrating the final application for the platform ultimately costing the program more money.
This white paper outlines the key challenges system integrators face when building a system with VPX COTS-based solutions and outlines some possible solutions.

A proven, mature integration infrastructure can help get to deployment faster, and eliminate many of the risks associated with COTS solution testing and integration. As a result, integrators can focus their efforts and resources on building the overall system solution and application, rather than testing the COTS-based components in the system.
