Worst Case RLC Noise with Timing Window Constraints
We study the problem of determining the switching patterns and switching times of multiple aggressors to generate the worst-case crosstalk noise (WCN) for a quiet victim in RLC interconnect structures under the constraints of both aggressor switching windows and the victim sampling window. We consider the signal routing direction and show that it has a significant impact under RLC model but not...
متن کاملInterconnect 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...
متن کاملAnalytical Modeling of Crosstalk Noise and Delay for High Speed On-chip Global Rlc Vlsi Interconnects
With the advancement of high frequency in the VLSI technology, the modeling of the interconnections is much important as the performance of the electronics systems is limited by interconnect related failure modes such as coupled noise and delay. Exact estimation of on-chip signal delay through RC tree network is difficult. Inductance causes noise in the signal waveforms, which can adversely aff...
متن کاملRouting issues in Nanometer-scale . . .
As integrated circuits (ICs) have scaled into nanometer dimensions, operating at gigahertz frequencies, interconnects have become critical in determining system performance, reliability, and manufacturability. This thesis presents new algorithms dealing with several important aspects of VLSI interconnects optimization and prediction, namely, noise reduction in global routing, temperature-aware ...
متن کاملCrosstalk Noise Modeling for RC and RLC interconnects in Deep Submicron VLSI Circuits
The crosstalk noise model for noise constrained interconnects optimization is presented for RC interconnects. The proposed model has simple closed-form expressions, which is capable of predicting the noise amplitude and the noise pulse width of an RC interconnect as well as coupling locations (near-driver and near-receiver) on victim net. This paper also presents a crosstalk noise model for bot...
