Due to the high availability demands placed on modern hardware systems and the high cost associated with downtime, nding and xing faults in these systems is an important problem. Unfortunately, the complexity of these systems is very large, making this problem very di cult. While recent innovations in the eld of model-based diagnosis have brought increased performance, making it a viable method...

A new approach to Fourier analysis within the context of circuit simulation is presented that is considerably more accurate and flexible than the traditional SPICE approach. It is based on the direct computation of the Fourier integral rather than on the discrete Fourier transform and so it is not subject to aliasing. It can be used to accurately compute a small number of Fourier coefficients f...

Standard Sneak Analysis procedures are costly from a time, money and personnel perspective. The processing of design data available only during the latter portions of the development cycle are highly labor intensive and difficult to institute a design change. Automated techniques for sneak analysis have been developed by several contractors for the workstation environment, but are either not co...

A broadband Circuit Analogue (CA) absorber using double-circular-loop array is investigated in this paper. A simple equivalent circuit model is presented to accurately analyze this CA absorber. The circuit simulation of the proposed model agrees well with full-wave simulations. Optimization based the equivalent circuit model, is applied to design a single-layer circuit analogue absorber using d...

This work is based on a new approach for minimizing energy consumption in quasi static energy recovery logic (QSERL) circuit which involves optimization by removing the non adiabatic losses completely. Energy recovering circuitry based on adiabatic principles is a promising technique leading towards lowpower high performance circuit design. The efficiency of such circuits may be increased by re...

An application called the Spice Internet Package (SIP) has been developed for use through the Internet and intranet networks. The SIP provides an interface that is operating independent, which allows Spice simulation and analysis to be performed from any computer that has a web browser on the Internet or intranet. One can access the Spice Internet Package and try some examples with the password...

Abstract: Transient analysis is an important circuit simulation technique. The circuit model, which is a system of differential-algebraic equations, is solved for a given initial condition using numerical time integration techniques. Multirate methods are efficient if the dynamical behaviour of the circuit model is not uniform. This paper deals with the analysis and control of the discretizatio...

The purpose of this brief is that, by an application of the method of characteristics, we analyze chaotic phenomena in Chua’s circuit with lossy transmission line. The transmission line is replaced by the equivalent lumped circuit and a time-delayed element so that it can be solved efficiently by the Runge-Kutta method. It is found from numerical experiments that the circuit has complicated and...

Transient noise analysis means time domain simulation of noisy electronic circuits. We consider mathematical models where the noise is taken into account by means of sources of Gaussian white noise that are added to the deterministic network equations, leading to systems of stochastic differential algebraic equations (SDAEs). A crucial property of the arising SDAEs is the large number of small ...
