A Runtime Stability Analysis of Clock Synchronization Precision on a Time-Triggered Bus Prototype

Abstract

This paper provides a runtime stability analysis of the DaisyChain clock synchronization algorithm running over CASCA -a time-triggered extension of CAN bus. The main objective is to show with practical results how to achieve global time base of high precision and how this precision is affected by the modification of the TDMA transmission schedule. That contributes by providing some basic guidelines for the task of designing time-triggered, TDMA-based distributed systems for embedded control applications.
