摘要

部分元件等效电路(PEEC)方法是将片上三维多导体结构转换为电路级描述的有效方法。本文描述了一种基于三角形网格的PEEC方法,其中任意形状的导电结构表面由三角形网格镶嵌表示。通过分离三角边基函数对之间的标量、矢量和欧姆电位相互作用,得到了耦合的电磁电路公式。整体方法可以解释为无spice,仅表面版本的PEEC方法,特别适用于片上系统布局的片上信号完整性分析,其中不规则形状的组件很常见。

Coupled electromagnetic-circuit simulation of arbitrarily-shaped conducting structures using triangular meshes
The partial-element-equivalent-circuit (PEEC) approach is an effective method to convert three-dimensional on-chip multiconductor structures to circuit-level descriptions. In this paper, a triangular-mesh-based PEEC approach is described, wherein the surfaces of arbitrarily-shaped conducting structures are represented by triangular mesh tesselations. A coupled EM-circuit formulation is obtained through the separation of the scalar, vector, and ohmic potential interactions between pairs of triangular edges-based basis functions. The overall approach can be interpreted as a SPICE-free, surface-only version of PEEC method and is especially useful for on-chip signal integrity analysis of systems-on-chip layout where components with irregular shapes are common.
