    • A method for performing a signal integrity analysis on an integrated circuit (IC) that includes a plurality of scatterers by dividing the scatterers into subgroups using a nested Huygens' equivalence principle algorithm and solving a set of equations realized thereby with a reduced coupling matrix. The method includes decomposing the IC design into a plurality of small non-overlapping circuit sub-domains, wherein each of the sub-domains is formed as a small, enclosed region. Each sub-domain is analyzed independently of the other sub-domains using only electric fields to represent the interactions of each sub-domains with the other sub-domains as equivalent currents on equivalent surfaces of the plurality of sub-domains. Neighboring equivalent sub-domains are grouped together to form larger sub-domains using equivalent currents on equivalent surfaces to represent the interactions of the sub-domains. The steps of analyzing and grouping the sub-domains are repeated until the grouping approaches a box comprising the entire domain, and that the domain interactions between every sub-domain have been analyzed.
    • 一种用于通过使用嵌套的惠更斯等效原理算法将散射体分成子组并且用减小的耦合矩阵求解由此实现的一组方程式来对包括多个散射体的集成电路(IC)进行信号完整性分析的方法。 该方法包括将IC设计分解为多个小的非重叠电路子域,其中每个子域形成为小的封闭区域。 仅使用电场来分析每个子域独立于其他子域,以将每个子域与其他子域的相互作用表示为多个子域的等效表面上的等效电流。 相邻的等效子域被分组在一起以形成较大的子域,使用等效表面上的等效电流来表示子域的相互作用。 重复分析和分组子域的步骤,直到分组接近包含整个域的框,并且分析了每个子域之间的域交互。
