节点电压方程 meaning in English

nodal voltage equation

First , to extract the rc parameters of the power grid . second , to extract cell currents of all the devices in the design . finally , to construct the nodal analysis equation of the power grid and solve it
电源网格的irdrop分析可分为三步来完成：首先提取电源网格的rc参数；然后计算各单元的工作电流；最后建立电源网格的节点电压方程，并求解各点的irdrop 。
Power grid integrity analysis can be implemented in four steps : first , to extract the r parameters of the power grid ; second , to partition the power grid when needed and in the same time extract the current ; third , to reduce the power grid efficiently ; and the last , to construct the nodal analysis equations of the global and local power grids and solve them
电源网格的irdrop分析可以分为四步完成：首先提取电源网格的版图参数；然后根据需要(通常根据网络大小)对电源网格进行划分，同时提取各实例的工作电流；对电源网格进行有效压缩；最后建立全局和子网网络的节点电压方程，求解各方程得到全部节点的电压降。
