摘要

电迁移(EM)是现代电路设计实践中一个重要的可靠性问题,它对当代集成电路的长期可靠性构成了相当大的风险,引起了EDA行业的关注。因此,开发一个强大的工业级EM分析工具至关重要。为了应对这一挑战,我们提出了PROTON,这是一个可以直接集成到工业设计流程中的开源工具,涵盖了广泛的EM分析需求。最重要的是,它提供了一个直观的图形用户界面,具有高水平的自动化,允许对电网设计的电磁应力分析进行可视化。质子的核心采用了最先进的方法,用于基于物理的电磁应力分析,为处理大规模电网设计提供了鲁棒性和可扩展性。与工业工具COMSOL在多个基准测试中进行了实验验证,其中质子的加速速度为×685,精度损失可以忽略不计。

PROTON – A Python Framework for Physics-Based Electromigration Assessment on Contemporary VLSI Power Grids
Electromigration (EM) is a significant reliability concern in modern circuit design practices that poses a considerable risk to the long-term reliability of contemporary integrated circuits and attracts attention from the EDA industry. Hence, the development of a robust, industrial-level EM analysis tool is crucial. In order to address this challenge, we present PROTON, an open-source tool that can be straightforwardly integrated into industrial design flows covering a wide spectrum of EM analysis needs. On top of this, it offers an intuitive graphical user interface with a high level of automation that allows the visualization of EM stress analysis on power grid designs. The core of PROTON incorporates state-of-the-art methodologies for physics-based EM stress analysis which provide robustness and scalability in handling large-scale power grid designs. These are experimentally verified in comparison with the industrial tool COMSOL on multiple benchmarks where PROTON demonstrated a speedup of ×685 with negligible loss in accuracy.
