State Linked Interface Compliance Engine for Data (SLICED)

Despite gains in component cohesion due to FACE's data-modeling standard and approach, integration of UoPs still presents a significant challenge for system integrators. The UoP data models required by FACE are necessary but not sufficient; FACE does not currently provide mechanisms to describe behavioral aspects of communication such as sampling rates, messaging patterns, latency requirements, and mode changes. These missing behavioral details lead to errors currently detectable only through manual, labor intensive review by system integrators.In State Linked Interface Compliance Engine for Data (SLICED) Phase I we demonstrated the feasibility of behavioral analysis by using minimally burdensome UoP state machines to detect failures including deadlock, latency, and race conditions. In Phase II, we propose maturing SLICED to TRL 7 by developing UoP behavior modeling guidelines, generating model views and inspection tools, creating FACE behavioral conformance testing tools, and demonstrating SLICED in Navy relevant operating environments.
