The Embedded Software of an Electrical Meter: An Experiment in Using Formal Methods in an Industrial Project

This article presents how various Formal Methods have been involved, rst on their own, then coupled, in the diierent steps of the industrial development of an embedded software for an electricity meter. Synchronized Transition Systems have been used to conceive and implement some Rendezvous mechanisms for the distributed kernel , and the physical link protocol supporting communication between processors. The Rate Monotonic Analysis model has been completed to suit some features of the product; however it appeared too rough to reach a positive issue. So we coupled both (Synchronized Transition Systems and Rate Monotonic Analysis) to achieve a ne analysis of the temporal properties of the system under development. This can be considered a rst step towards Formal Methods Engineering.
