Expedite Stochastic SPICE Simulations by Means of Polynomial Chaos
نویسندگان
چکیده
The impact on circuit performance of parameters uncertainties can be effectively evaluated by describing the resulting stochastic problem in terms of orthogonal polynomial expansions of electrical quantities. This contribution formalizes a rule for the construction of an augmented instance of the original circuit, that provides a systematic solution for the unknown coefficients of the expanded variables. The use of SPICE as a solution engine of the augmented circuit provides a convenient and efficient alternative to the conventional approach SPICE uses for uncertainty analysis. Index terms : Circuit modeling, Polynomial chaos, Circuit simulation, Transmission lines, Stochastic analysis, Tolerance analysis, Uncertainty.

Simulation of stochastic systems via polynomial chaos expansions and convex optimization
Polynomial chaos expansions represent a powerful tool to simulate stochastic models of dynamical systems. Yet, deriving the expansion's coefficients for complex systems might require a significant and nontrivial manipulation of the model, or the computation of large numbers of simulation runs, rendering the approach too time consuming and impracticable for applications with more than a handful ...
متن کاملEfficient estimation of polynomial chaos proxies using generalized sparse quadrature
We investigate the use of sparse grid methods in computing polynomial chaos (PC) proxies for forward stochastic problems associated with numerically-expensive simulators. These are problems where some input parameters are random with known distributions, and stochastic properties of the simulator output are desired. The bottleneck for PC proxy construction is the estimation of the coefficients,...
متن کاملModeling Uncertainty in Steady State Diffusion Problems via Generalized Polynomial Chaos
We present a generalized polynomial chaos algorithm for the solution of stochastic elliptic partial differential equations suject to uncertain inputs. In particular, we focus on the solution of the Poisson equation with random diffusivity, forcing and boundary conditions. The stochastic input and solution are represented spectrally by employing the orthogonal polynomial functionals from the Ask...
متن کاملOn the stochastic behaviors of locally confined particle systems.
We investigate a class of Hamiltonian particle systems and their stochastic behaviors. Using both rigorous proof and numerical simulations, we show that the geometric configuration can qualitatively change key statistical characteristics of the particle system, which are expected to be retained by stochastic modifications. In particular, whether a particle system has an exponential mixing rate ...
متن کاملPolynomial Chaos for Semiexplicit Differential Algebraic Equations of Index 1
Mathematical modeling of technical applications often yields systems of differential algebraic equations. Uncertainties of physical parameters can be considered by the introduction of random variables. A corresponding uncertainty quantification requires one to solve the stochastic model. We focus on semiexplicit systems of nonlinear differential algebraic equations with index 1. The stochastic ...
