Accurate Inductance Extraction with Permeable Materials Using Qualocation
نویسندگان
چکیده
In this paper we present a more accurate method for solving a frequency-dependent inductance of 3-D structures that contains permeable materials. The extracted inductance using the new method is much more accurate than when using the traditional collocation method for no increased cost. Computational results are presented and compared with data to demonstrate the accuracy improvement of the approach.

Numerical solution of boundary-integral equations for molecular electrostatics.
Numerous molecular processes, such as ion permeation through channel proteins, are governed by relatively small changes in energetics. As a result, theoretical investigations of these processes require accurate numerical methods. In the present paper, we evaluate the accuracy of two approaches to simulating boundary-integral equations for continuum models of the electrostatics of solvation. The...

Abstract: For high-speed circuits, on-chip inductance can no longer be ignored. This paper deals with inductance in the presence of multi-layered meshes used for on-chip power supplies. We have shown ways of designing power/ground (p/g) mesh that reduce inductance. Accurate 3-dimensional inductance extraction problem is intractable for large chips. We have demonstrated the feasibility of using ...
متن کاملOn the Extraction of On-Chip Inductance
Inductance extraction has become an important issue in the design of high speed CMOS circuits. Two characteristics of on-chip inductance are discussed in this paper that can significantly simplify the extraction of on-chip inductance. The first characteristic is that the sensitivity of a signal waveform to errors in the inductance values is low, particularly the propagation delay and the rise t...

Inductance has been identified as an emerging troublemaker of interconnects for the next generation high-speed digital VLSI design. As a result, accurate and fast inductance extraction is of crucial importance. Formulae-based partial inductance extraction method approaches have been widely adopted for inductance extraction due to its simplicity and efficiency. However, there are so many inducta...

Practical approaches for on-chip inductance extraction to obtain a sparse, stable and accurate inverse inductance matrix K are proposed. The novelty of our work is in using circuit characteristics to define the concept of resistance-dominant and inductancedominant lines. This notion is used to progressively refine a set of clusters that are inductively tightly-coupled. For reasonable designs, t...
