A Self-Reconfiguring IEEE 1687 Network for Fault Monitoring


Summary, in English

Efficient handling of faults during operation is highly dependent on the interval (latency) from the time embedded instruments detect errors to the time when the fault manager localizes the errors. In this paper, we propose a self-reconfiguring IEEE 1687 network in which all instruments that have detected errors are automatically included in the scan path. To enable self-reconfiguration, we propose a modified segment insertion bit (SIB) compliant to IEEE 1687. We provide time analyses on error detection and fault localization for single and multiple faults, and we suggest how the self-reconfiguring IEEE 1687 network should be designed such that time for error detection and fault localization is kept low and deterministic. For validation, we implemented and performed post-layout simulations for one self-reconfiguring network. We show that compared to previous schemes, our proposed network significantly reduces the fault localization time.
