1. **会议与主题**:2025年1月28-30日圣克拉拉会议中心,华为团队提出高效时序感知电源完整性分析(TAPIA)方法。 2. **传统方法局限**:目标阻抗分析无法捕捉时域电流行为;集总/分布式模型仿真难以精确评估模块噪声及最小工作电压(Vmin)。 3. **TAPIA核心**:通过时序路径分析量化电源噪声影响(PSIJ、RJ、DCD),结合动态抖动库(DJLs)重建时序性能,确定Vmin/Vmax。 4. **验证结果**:两颗芯片实测与仿真Vmin误差仅10mV(SS角0℃),证明方法准确性,避免过设计降低成本。
**TAPIA优势?** **PSIJ如何计算?** **Vmin如何验证?**
