Programmers creating mission-critical applications — embedded control applications, industrial monitoring applications, and high-performance test systems — cannot afford to introduce errors or uncertainty into the system. The stakes are especially high in medical applications, where failure can often lead to patient injury and costly product recalls.
This paper provides a runtime stability analysis of the Daisy-Chain 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.
