EMPIRE: An Efficient and Compact Multiple-Parameterized Model Order Reduction Method
نویسندگان
چکیده
In physical design and optimization for VLSI/ULSI, parameterized model order reduction can be used to handle large design objectives. In this paper we propose an efficient yet accurate parameterized model order reduction method EMPIRE for physical design with multiple parameters. It is the first practical algorithm using implicit moment matching to handle high order moments of very large number of parameters. In addition, it can match the moments of different parameters with different accuracy according to their influence on the objective under study. Experiment results show that compared with the best existing algorithm CORE which uses explicit moment matching for the parameters, EMPIRE results in 47.8X improved accuracy at a similar runtime.

We present an efficient method for the reduction of model equations in the linearized diffuse optical tomography (DOT) problem. We first implement the maximum a posteriori (MAP) estimator and Tikhonov regularization, which are based on applying preconditioners to linear perturbation equations. For model reduction, the precondition is split into two parts: the principal components are consid...

This paper describes a flexible and efficient new algorithm for model order reduction of parameterized systems. The method is based on the reformulation of the parameterized system as a perturbation-like parallel interconnection of the nominal transfer function and the non-parameterized transfer function sensitivities with respect to the parameter variations. Such a formulation reveals an expli...
