摘要

配电网分析是配电网设计规划的重要内容之一。一个典型的经验法则是20%的路由资源分配给配电网。然而，随着多芯片封装的2.5D封装的引入，由于中间层中额外的IR下降，功耗预算分配仍然宽松，因此配电网络工程变更顺序(ECO)是设计实施流程的函数，有待探索和部署。本文将分享设计中的配电网ECO和结果。与EDA工具的开箱即用解决方案相比，设计中的无缝配电网络ECO可将IRDrop提高7%。

Automated IRDrop ECO

Power Distribution Network (PDN) Analysis is one of the important aspects in design planning. A typical rule of thumb is 20% of the routing resources allocated for power distribution network. However, with the introduction of 2.5D packaging for multi-chip on package, the power budget allocation is yet relax for additional IR Drop in interposer layers, hence a power distribution network engineering change order (ECO) is a function of design implementation flow, to be explored and deployed. This paper will share the in-design power distribution network ECO and results. The seamless in-design power distribution network ECO results in 7% IRDrop improvement compared to out of the box solutions from EDA tools.
