Cyber-Physical Systems: Design and Verification Challenges

Overview

Abstract

A Cyber-Physical Systems (CPS) is primarily composed of several electronic, communication and controller modules and some physical actuators and sensors. The mix of heterogeneous underlying technologies poses a number of technical challenges to the design and more severely to the analysis of such complex infrastructure. In fact, a CPS shall adhere to strict safety, reliability, performance and security requirements, where on needs to capture both physical and random aspects of the various CPS modules and then analyze their inter-relationship. Oftentimes however, system bugs remain uncaught during the analysis and in turn cause unwanted scenarios that may have serious consequences in safety critical applications. In this talk, we discuss some of the challenges surrounding the design and verification of contemporary CPS with the advent of smart technologies. In particular, we will introduce recent developments in the use of formal methods for the modeling, analysis and verification of CPS and display a few real world CPS case studies using physical components based on photonics integrated circuits.
