Overview of SOIS Electronic Data Sheets (EDS) & Dictionary of Terms (DoT) SOIS APP WG Fall 2012

Origin: ICD Present Scope of Interface Control Documents – Inputs and outputs of a single system – Interface between two specific systems – Complete protocol stack from physical to application layer for one component Criticism of ICD’s – Static documentation of detail that becomes out of sync with actual component – Human communication is sometimes necessary for clarity – Not machine readable for automated development processes

Flight SW components Design, Development, Operations, Maintenance – Automated tools supporting multiple flight and ground systems and components from a single source Designer and/or tools Component EDS Component (software) EDS Models Component EDS Device EDS Models Test procedures Test/Simulation tool/consoles Ground Systems Models Operations procedures Ground System Database(s) Page Displays Models Simulators Flight SW components Flight SW components Dictionary of Terms
