A Comprehensive Soft Error Analysis Tool For Core Networking System

In this paper, we developed a comprehensive single-event upset (SEU) analysis tool. To achieve this goal we start by defining the SEU mitigation strategy as a combination of chip level methods and system level methods. Given a particular SEU chip level and/or system level mitigation choice, we propose first categorizing the SEU Failure In Time (FIT) into different time window bins based on SEU recovery time. Then we analyze the impact of each mitigation strategy, results in the FIT value change in each bin. This tool enables the engineers to do the SEU mitigation design in early design phase. A user-friendly Excel format is also developed to make the complicated model easy to use.
