- The design process for automotive electronics isan iterative process, where new components and distributedapplications are added over several design cycles incrementally.Hence, at each design iteration an existing communicationschedule is extended by new messages that have to be scheduledappropriately. In this paper, the goal has been to synthesizeschedules under real-time constraints for the dynamic segmentof FlexRay with respect to the 64-cycle protocol specification. Wepropose a flexible scheduling framework to generate all feasibleschedules for a set of messages satisfying real-time and protocolconstraints. Further, we present an optimization procedure toretain schedules according to suitable design metrics. Eventhough the size of the possible design space is exponential inthe number of messages, our proposed method keeps down theschedule synthesis time to practically acceptable values as shownin the experiments.
