We propose a root-causing procedure for accelerating system-level debug using
rule-based techniques. We describe the procedure and how it provides high
quality debug hints for reducing the debug effort. This includes the heuristics
for engineering features from logs of many tests, and the data analytics
techniques for generating powerful debug hints. As a case study, we used these
techniques for root-causing failures of the Power Management (PM) design
feature Package-C8 and showed their effectiveness. Furthermore, we propose an
approach for mining the root-causing experience and results for reuse, to
accelerate future debug activities and reduce dependency on validation experts.
We believe that these techniques are beneficial also for other validation
activities at different levels of abstraction, for complex hardware, software
and firmware systems, both pre-silicon and post-silicon.

通过基于规则的技术提出一种系统级调试加速的原因分析流程，使用多项测试的日志提取工程特征和数据分析技术生成高质量的调试提示，以 Power Management (PM) 设计功能 Package-C8 的故障排除为案例研究并展示了它们的有效性，还提出了一种挖掘原因分析经验和结果以加速未来调试活动并减少验证专家依赖的方法，我们相信这些技术对于复杂的硬件、软件和固件系统，以及不同抽象层次的验证活动，无论是硅前还是硅后，都是有益的。
