ADVENTIUM ENTERPRISES, LLC — National Aeronautics and Space Administration SBIR Phase I: H6

Description

The Stakeholder Access to Embedded System Models (SAESM)nbsp; project will produce a vendor neutral model-based systems engineering (MBSE)nbsp; analysis environment that supports Consultative Committee for Space Data Systems (CCSDS) Spacecraft Onboard Interface Services standard Electronic Data Sheet (SEDS) generation from existing models, e.g., models written in System Modeling Language (SysML), Future Airborne Capability Environment (FACE), and Architecture Analysis and Design Language (AADL),nbsp; ingestion of existing SEDS into the environment, and virtual integration of the systemrepresented in the environment.nbsp; Virtual integration is a process of analyzing detailed models of embedded software systems to uncover errors primarily related to non-functional requirements, including timing, safety, and security.nbsp; These errors are generally not uncovered until integration and test phases when costs to fix them are prohibitive. SAESM will enable multiple stakeholders to conduct these analyses without requiring expert knowledge of the underlying modeling language(s).nbsp; SAESM supports vendors by enabling them to support NASArsquo;s SEDS initiative using modeling languages they are already using, supports NASA personnel by automatically creating and maintaining SEDS, and supports all parties with virtual integration. This improves system capability by reducing risk of cost and schedule overruns due to late discovery of errors.
