چکیده
The solution of Maxwell's equations for irregular 3D structures have been used traditionally for oil-exploration, detection of radar-cross-section of military vehicles, antenna analysis, bio-medical applications and more recently in predicting electrical performance of RF and high speed circuits and systems. Since 1950s applied mathematics, physics, and engineering communities have refined the EM solution using 3 fundamental analysis techniques: Finite Element Method (FEM), Finite Difference Time Domain (FDTD) method and the Method of Moments (MoM) or the Boundary Element Method (BEM). The accuracy of simulated results and the time and memory requirements are key indicators of any solution methodology. While the community has successfully addressed many challenges over the last two decades, several problems including fast direct solvers, effective full-wave preconditioners, incremental or design specific solvers, parallelization of certain fast iterative solvers remain unsolved or partially solved.

An Iteration-free Fast Multilevel Solver for Dense Method of Moment Systems
A fast multilevel direct solver for the Method of Moments applied to electrically small structures is presented. The approach is based on a combination of low-rank decompositions and fill-in control. It is particularly advantageous for multiple right-hand-side problems such as those encountered in digital circuit and IC analyses, as is demonstrated by numerical simulation results presented here.
متن کاملPilot: a Fast Algorithm for Enhanced 3d Parasitic Capacitance Extraction Efficiency
Integral-equation methodologies applied to extract parasitics for board, package, and on-chip structures involve solving a dense system of equations. In this paper, we present an improved matrix-compression technique for fast iterative solution of such dense systems, which applies QR decomposition on multilevel oct-tree-based interaction sub-matrices. The regular-tree structure of the fast-mult...

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...

In this paper, a new formulation for coupled electromagnetic-circuit simulation is presented. The formulation employs full-wave integral equations to model the electromagnetic (EM) behavior of 2D or 3D structures while using modified nodal analysis (MNA) to model circuit interactions. A coupling scheme based on charge and current continuity and potential matching, realized as a generalization o...
