Abstract:

An input/output--link control protocol is modeled and analyzed in the real-time model checker Uppaal. The protocol is supposed to sit in an audio/video component and control (read from and write to) a link to neighbour audio/video components. The component may for example be a TV, and a neighbour may be a VCR. The protocol also communicates with the remote--control. The protocol is in addition responsible for the powering up and down of the component in between the arrival of data. It is this power control that is the focus of the modeling and verification demonstrated in this report. The work has been carried out in a collaboration between Aalborg University and the audio/video company B&O, which plans to incorporate the protocol as part of a new product line. The work was carried out in a limited period of 3 weeks, with an attempt to examine how well such a collaboration would proceed. The paper elaborates on the lessons learned.
