Crosstalk has become a major issue in VLSI design due to the high fr equency, long interconnecting lines and small spacing between interconnects in today's integrated circuits. In this paper, we study the problem of crosstalk minimization in 3-layer HVH channel routing. A heuristic algorithm that combines layer reassignment and track reassignment is presented. This algorithm can iteratively mod...

This paper reviews different encoding schemes for reduction of power dissipation, crosstalk noise and delay. Crosstalk is aggravated by enhanced switching activity which is often main cause for the malfunctioning of any VLSI chip. Consequently, delay and power dissipation also increases due to enhanced crosstalk. Reduction in switching activities through coupled transmission line results in eno...

| The inter-wire spacing in a VLSI chip becomes closer as the VLSI fabrication technology rapidly evolves. Accordingly, it becomes important to consider crosstalk caused by the coupling capacitance between adjacent wires in the layout design for the fast and safe VLSI circuits. The upper bounds of the allowable crosstalk for nets, called cross-talk constraints, are usually given in the design s...

This paper explores how fluctuating crosstalk in a deterministic fitness function introduces noise into genetic algorithms. We model fluctuating crosstalk or nonlinear interactions among building blocks via higher-order Walsh coefficients. The fluctuating crosstalk behaves like exogenous noise and can be handled by increasing the population size and run duration. This behavior holds until the s...

In this paper we propose a coding scheme for general-purpose applications that can reduce power dissipation, crosstalk noise and crosstalk delay on the bus lines while simultaneously detecting errors at run time. The reduction in power dissipation can be achieved through reducing the bus switching activity. Not only is the switching activity in individual lines reduced but so is the coupling ac...

Stereoscopic three-dimensional (3D) services have become more popular recently amid promise of providing immersive quality of experience (QoE) to the end-users with the help of binocular depth. However, various arisen artifacts in the stereoscopic 3D processing chain might cause discomfort and severely degrade the QoE. Unfortunately, although the causes and nature of artifacts have already been...

All-to-all broadcast is to disseminate a unique message from each node to every other node of the network. This paper investigates the impact of some of the physical layer impairments on the optical all-to-all broadcast in linear array, bidirectional ring and hypercube networks. The physical layer impairments include Amplified Spontaneous Emission (ASE) noise, switch induced crosstalk and demux...

In this paper noise avoidance in closed form crosstalk noise model for on-chip VLSI RC interconnects using 2π model is presented. In this crosstalk noise model we consider the case when step input is applied to the aggressor which is adjacent to the victim net and further simplified it, then find out the closed form formulae for noise pulse width and noise amplitude for RC interconnect. Various...

In this paper we develop a general methodology to analyze crosstalk to obtain insight into effects that are likely to cause errors in deep submicron high speed circuits. We focus on crosstalk due to capacitive coupling between a pair of lines. We first consider the case where crosstalk noise manifests as a pulse and characterize the maximum amplitude, width, energy and timing of this pulse. Clo...

Optical crosstalk seriously limits the photon-counting resolution of silicon photomultipliers. In this work, realistic analytical models to describe the crosstalk effects on the response of these photodetectors are presented and compared with experimental data. The proposed models are based on the hypothesis that each pixel of the array has a finite number of available neighboring pixels to exc...
