Language Semantics Driven Design and Formal Analysis for Distributed Cyber-Physical Systems: [Extended Abstract]

Abstract

Typically platform specific programming models for distributed Cyber-Physical Systems provide limited portability, code reuse, rigorous verification, and synthesis. Koord is a new distributed CPS programming model and language, which treats the platform-independent decision and coordination tasks as a separate concern from platform-dependent concerns of low-level sensing, communication, and control. Koord features event-based programming, shared variables for convenient coordination across multiple agents, and interfaces defined by sensor and actuator ports for the (platform independent) application program to interface with program's environment consisting of controllers and the physical plant. We implement the executable semantics of Koord in the \K framework. The Koord framework also includes formal analysis tools on top of the semantics to enable semantics driven-verification.
