Crosstalk In Modern On Chip Interconnects

The book provides accurate FDTD models for on-chip interconnects, covering most recent advancements in materials and design. Furthermore, depending on the geometry and physical configurations, different electrical equivalent models for CNT and GNR based interconnects are presented. Based on the electrical equivalent models the performance comparison among the Cu, CNT and GNR-based interconnects are also discussed in the book. The proposed models are validated with the HSPICE simulations. The book introduces the current research scenario in the modeling of on-chip interconnects. It presents the structure, properties, and characteristics of graphene based on-chip interconnects and the FDTD modeling of Cu based on-chip interconnects. The model considers the non-linear effects of CMOS driver as well as the transmission line effects of interconnect line that includes coupling capacitance and mutual inductance effects. In a more realistic manner, the proposed model includes the effect of width-dependent MFP of the MLGNR while taking into account the edge roughness.

Noise Coupling is the root-cause of the majority of Systems on Chip (SoC) product fails. The book discusses a breakthrough substrate coupling analysis flow and modelling toolset, addressing the needs of the design community. The flow provides capability to analyze noise components, propagating through the substrate, the parasitic interconnects and the package. Using this book, the reader can analyze and avoid complex noise coupling that degrades RF and mixed signal design performance, while reducing the need for conservative design practices. With chapters written by leading international experts in the field, novel methodologies are provided to identify noise coupling in silicon. It additionally features case studies that can be found in any modern CMOS SoC product for mobile communications, automotive applications and readout front ends.

Deep Sub-Micron (DSM) processes present many changes to Very Large Scale Integration (VLSI) circuit designers. One of the greatest challenges is crosstalk, which becomes significant with shrinking feature sizes of VLSI fabrication processes. The presence of crosstalk greatly limits the speed and increases the power consumption of the IC design. This book focuses on crosstalk avoidance with bus encoding, one of the techniques that selectively mitigates the impact of crosstalk and improves the speed and power consumption of the bus interconnect. This technique encodes data before transmission over the bus to avoid certain undesirable crosstalk conditions and thereby improve the bus speed and/or energy consumption.

Recent advances in semiconductor technology offer vertical interconnect access (via) that extend through silicon, popularly known as through silicon via (TSV). This book provides a comprehensive review of the theory behind TSVs while covering most recent advancements in materials, models and designs. Furthermore, depending on the geometry and physical configurations, different electrical equivalent models for Cu, carbon nanotube (CNT) and graphene nanoribbon (GNR) based TSVs are presented. Based on the electrical equivalent models the performance comparison among the Cu, CNT and GNR based TSVs are also discussed.

This book presents an updated selection of the most representative contributions to the 2nd and 3rd IEEE Workshops on Signal Propagation on Interconnects (SPI) which were held in Travemtinde (Baltic See Side), Germany, May 13-15, 1998, and in Titisee-Neustadt (Black Forest), Germany, May 19-21, 1999. This publication addresses the need of developers and researchers in the field of VLSI chip and package design. It offers a survey of current problems regarding the influence of interconnect effects on the electrical performance of electronic circuits and suggests innovative solutions. In this sense the present book represents a continua tion and a supplement to the first book "Signal Propagation on Interconnects", Kluwer Academic Publishers, 1998. The papers in this book cover a wide area of research directions: Beneath the des cription of general trends they deal with the solution of signal integrity problems, the modeling of interconnects, parameter extraction using calculations and measurements and last but not least actual problems in the field of optical interconnects.

In Interconnect-centric Design for Advanced SoC and NoC, we have tried to create a comprehensive understanding about on-chip interconnect characteristics, design methodologies, layered views on different abstraction levels and finally about applying the interconnect-centric design in system-on-chip design. Traditionally, on-chip communication design has been done using rather ad-hoc and informal approaches that fail to meet some of the challenges posed by next-generation SOC designs, such as performance and throughput, power and energy, reliability, predictability, synchronization, and management of concurrency. To address these challenges, it is critical to take a global view of the communication problem, and decompose it along lines that make it more tractable. We believe that a layered approach similar to that defined by the communication networks community should also be used for on-chip communication design. The design issues are handled on physical and circuit layer, logic and architecture layer, and from system design methodology and tools point of view. Formal communication modeling and refinement is used to bridge the communication layers, and network-centric modeling of multiprocessor on-chip networks and socket-based design will serve the development of platforms for SoC and NoC integration. Interconnect-centric Design for Advanced SoC and NoC is concluded by two application examples: interconnect and memory organization in SoCs for advanced set-top boxes and TV, and a case study in NoC platform design for more generic applications.

This book addresses two main problems with interconnections at the chip and package level: crosstalk and simultaneous switching noise. Its orientation is towards giving general information rather than a compilation of practical cases. Each chapter contains a list of references for the topics.
