Abstract

Time is a foundational aspect of Cyber-Physical Systems (CPS). Correct time and timing of system events is critical to optimized responsiveness to the environment, in terms of timeliness, accuracy and precision in the knowledge, measurement, prediction, and control of CPS behavior. However typically both the specification and verification of timing requirements of the CPS are done in an ad-hoc manner. While feasible, the system can become costly and difficult to analyze and maintain, and the process of implementing and verifying correct timing behavior can be error-prone. Towards the development of a verification testbed for testing timing behavior in tools and platforms with explicit time support, this paper first describes a way to express the various kinds of timing constraints in distributed CPS. Then we outline our idea and implementation of a distributed testbed to verify the timing of a distributed CPS analytically through a systematic framework. Finally, we illustrate the use of the timing testbed on two distributed CPS case studies..
