چکیده

We present a new realizable reduced order modeling technique for RLC interconnect trees. Both lumped and distributed wire models can be used with this technique. Provable stability is achieved by using Hurwitz polynomials. Moment computation process is avoided but moments can still be matched implicitly. In experiments, the proposed Hurwitz three-pole model can accurately and efficiently capture inductive effect for both near end and far end nodes.

RLC Equivalent Circuit Synthesis Method for Structure-Preserved Reduced-Order Model of Interconnect in VLSI

This paper aims to explore RLC equivalent circuit synthesis method for reduced-order models of interconnect circuits obtained by Krylov subspace based model order reduction (MOR) methods. To guarantee pure RLC equivalent circuits can be synthesized, both the structures of input and output incidence matrices and the block structure of the circuit matrices should be preserved in the reduced-order...

A Coordinate-transformed Arnoldi Algorithm for Generating Guaranteed Stable Reduced-order Models of Arbitrary Rlc Circuits

Since the rst papers on asymptotic waveform evaluation (AWE), Pad e-based reduced order models have become standard for improving coupled circuit-interconnect simulation eeciency. Such models can be accurately computed using bi-orthogonalization algorithms like Pad e via Lanczos (PVL), but the resulting Pad e approximates can still be unstable even when generated from stable RLC circuits. For c...

DTT: direct truncation of the transfer function - an alternative tomoment matching for tree structured interconnect

A method is introduced to evaluate time domain signals within RLC trees with arbitrary accuracy in response to any input signal. This method depends on finding a low frequency reduced-order transfer function by direct truncation of the exact transfer function at different nodes of an RLC tree. The method is numerically accurate for any order of approximation, which permits approximations to be ...

Interconnect layout optimization under higher order RLC model forMCM designs

In this paper, we study the interconnect layout optimization problem under a higher-order RLC model to optimize not only delay, but also waveform, for interconnects with non-monotone signal response in the context of MCM global routing. We propose a unified approach that considers topology optimization and waveform optimization simultaneously. Using a new incremental moment computation algorith...

cient Analyses and Models of VLSI and MCM Interconnects

In performance-driven interconnect design, delay estimators are used to determine both the topol-ogy and the layout of good routing trees. We address the class of moment-matching methods used to model distributed RLC interconnects with a small number of lumped segment models. We provide new non-uniform segment models which match the transfer function of a general interconnect line with source a...
