Available in PDF, EPUB and Kindle. Book excerpt: Through silicon via (TSV) based 3D integrated circuits have inspired a novel design paradigm which explores the vertical dimension, in order to alleviate the performance and power limitations associated with long interconnects in 2D circuits. TSVs enable vertical interconnects across stacked and thinned dies in 3D-IC designs, resulting in reduced wirelength, footprint, faster speed, improved bandwidth, and lesser routing congestion. However, the usage of TSVs itself gives rise to many critical design challenges towards the minimization of chip delay and power consumption. Therefore, realization of the benefits of 3D ICs necessitates an early and realistic prediction of circuit performance during the early layout design stage. The goal of this thesis is to meet the design challenges of 3D ICs by providing new capabilities to the existing floorplanning framework [87]. The additional capabilities included in the existing floorplanning tool is the co-placement of TSV islands with circuit blocks and performing non-deterministic assignment of signals to TSVs. We also replace the wirelength and number of TSVs in the floorplanning cost function with the total delay in the nets. The delay-aware cost function accounts for RC delay impact of TSVs on the delay of individual signal connection, and obviates the efforts required to balance the weight contributions of wirelength and TSVs in the wirelength-aware floorplanning. Our floorplanning tool results in 5% shorter wirelength and 21% lesser TSVs compared to recent approaches. The delay in the cost function improves total delay in the interconnects by 10% - 12% compared to wirelength-aware cost function. The influence of large coupling capacitance between TSVs on the delay, power and coupling noise in 3D interconnects also offers serious challenges to the performance of 3D-IC. Due to the degree of design complexity introduced by TSVs in 3D ICs, the importance of early stage evaluation and optimization of delay, power and signal integrity of 3D circuits cannot be ignored. The unique contribution of this work is to develop methods for accurate analysis of timing, power and coupling noise across multiple stacked device layers during the floorplanning stage. Incorporating the impact of TSV and the stacking of multiple device layers within floorplanning framework will help to achieve 3D layouts with superior performance. Therefore, we proposed an efficient TSV coupling noise model to evaluate the coupling noise in the 3D interconnects during floorplanning. The total coupling noise in 3D interconnects is included in the cost function to optimize positions of TSVs and blocks, as well as nets-to-TSVs assignment to obtain floorplans with minimized coupling noise. We also suggested diagonal TSV arrangement for larger TSV pitch and nonuniform pitch arrangement for reducing worst TSV-to-TSV coupling, thereby minimizing the coupling noise in the interconnects. This thesis also focuses on more realistic evaluation and optimization of delay and power in TSV based 3D integrated circuits considering the interconnect density on individual device layers. The floorplanning tool uses TSV locations and delay, non-uniform interconnect density across multiple stacked device layers to assess and optimize the buffer count, delay, and interconnect power dissipation in a design. It is shown that the impact of non-uniform interconnect density, across the stacked device layers, should not be ignored, as its contribution to the performance of the 3D interconnects is consequential. A wire capacitance-aware buffer insertion scheme is presented that determines the optimal distance between adjacent buffers on the individual device layers for nonuniform wire density between stacked device layers. The proposed approach also considers TSV location on a 3D wire to optimize the buffer insertion around TSVs. For 3D designs with uniform wire density across stacked device layers, we propose a TSV-aware buffer insertion approach that appropriately models the TSV RC delay impact on interconnect delay to determine the optimum interval between adjacent buffers for individual 3D nets. Moreover, our floorplanning tool help achieve 3D layouts with superior performance by incorporating the impact of nonuniform density on the delay, power and coupling noise in the interconnects during floorplanning.

This book was released on 2012-09-23 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the challenges and presents best strategies for designing Through-Silicon Vias (TSVs) for 3D integrated circuits. It describes a novel technique to mitigate TSV-induced noise, the GND Plug, which is superior to others adapted from 2-D planar technologies, such as a backside ground plane and traditional substrate contacts. The book also investigates, in the form of a comparative study, the impact of TSV size and granularity, spacing of C4 connectors, off-chip power delivery network, shared and dedicated TSVs, and coaxial TSVs on the quality of power delivery in 3-D ICs. The authors provide detailed best design practices for designing 3-D power delivery networks. Since TSVs occupy silicon real-estate and impact device density, this book provides four iterative algorithms to minimize the number of TSVs in a power delivery network. Unlike other existing methods, these algorithms can be applied in early design stages when only functional block- level behaviors and a floorplan are available. Finally, the authors explore the use of Carbon Nanotubes for power grid design as a futuristic alternative to Copper.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to explore the feasibility of addressing the major performance and reliability problems or issues, such as wirelength, stress-induced carrier mobility variation, temperature, and quality trade-offs, found in three-dimensional integrated circuits (3D ICs) that use through-silicon vias (TSVs) at placement stage. Four main works that support this goal are included. In the first work, wirelength of TSV-based 3D ICs is the main focus. In the second work, stress-induced carrier mobility variation in TSV-based 3D ICs is examined. In the third work, temperature inside TSV-based 3D ICs is investigated. In the final work, the quality trade-offs of TSV-based 3D-IC designs are explored. In the first work, a force-directed, 3D, and gate-level placement algorithm that efficiently handles TSVs is developed. The experiments based on synthesized benchmarks indicate that the developed algorithm helps generate GDSII layouts of 3D-IC designs that are optimized in terms of wirelength. In addition, the impact of TSVs on other physical aspects of 3D-IC designs is also studied by analyzing the GDSII layouts. In the second work, the model for carrier mobility variation caused by TSV and STI stresses is developed as well as the timing analysis flow considering the stresses. The impact of TSV and STI stresses on carrier mobility variation and performance of 3D ICs is studied. Furthermore, a TSV-stress-driven, force-directed, and 3D placement algorithm is developed. It exploits carrier mobility variation, caused by stress around TSVs after fabrication, to improve the timing and area objectives during placement. In addition, the impact of keep-out zone (KOZ) around TSVs on stress, carrier mobility variation, area, wirelength, and performance of 3D ICs is studied. In the third work, two temperature-aware global placement algorithms are developed. They exploit die-to-die thermal coupling in 3D ICs to improve temperature during placement. In addition, a framework used to evaluate the results from temperature-aware global placements is developed. The main component of the framework is a GDSII-level thermal analysis that considers all structures inside a TSV-based 3D IC while computing temperature. The developed placers are compared with several state-of-the-art placers published in recent literature. The experimental results indicate that the developed algorithms help improve the temperature of 3D ICs effectively. In the final work, three block-level design styles for TSV-based die-to-wafer bonded 3D ICs are discussed. Several 3D-IC layouts in the three styles are manually designed. The main difference among these layouts is the position of TSVs. Finally, the area, wirelength, timing, power, temperature, and mechanical stress of all layouts are compared to explore the trade-offs of layout quality.

This book was released on 2020 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through-silicon via (TSV)-based three-dimensional integrated circuits (3D ICs) are expected to be the breakthrough technology for keeping up with the scaling trends of Moore's law, while also offering the unique opportunity for functional diversification through heterogenous integration. TSVs are vertical metal interconnects enabling communication across stacked and thinned dies. The dramatic reduction in global wirelength and chip footprint in 3DICs, directly improves delay, device density, bandwidth and routing congestion. Even with the current maturation of TSV process, the roadmap for industry adoption of 3DICs remains largely uncertain due to lack of standardized 3D tools capable of handling the sheer complexity of the three-dimensional solution space. Many critical design issues arise due to usage of TSVs. Large-sized TSVs, introduce significant area and delay overhead. The increased risk of TSV failure during fabrication or bonding, causes long-term reliability issues and loss of yield. The earlier these critical issues are addressed in the design cycle, the better our chances are of making realistic performance predictions and informed decisions, for speeding-up convergence. 3D floorplanning constitutes an important first step of layout design, providing early feedback on critical performance metrics, i.e., area, wirelength, delay, power and wiring density. Since the resulting floorplan impacts the optimization of all subsequent stages, there is a critical need for efficient TSV-aware layout design exploration tools, which can accurately characterize the physical and electrical impact of TSVs. A key concept of this thesis is that interconnect performance in 3D chips is directly controlled by the quality of the generated 3D floorplan, which is fundamentally impacted by the heuristics guiding the search and evaluation of floorplan. In support of this view, the core objective of this thesis is to develop an efficient methodology to improve the 3D floorplan solution quality. By generating more realistic 3D layouts, we seek to improve the accuracy of evaluation of the goodness of a 3D floorplan. A new dynamic TSV clustering algorithm is introduced, which simultaneously optimizes the sizes and positions of TSV clusters on the layout. This is the first work to consider the direct minimization of TSV occupied area at the floorplanning stage. As the generated floorplan is independent of any fixed arrangement of TSVs as input, it facilitates a more realistic and accurate evaluation of floorplan metrics. A novel nets-to-TSVs assignment algorithm which considers the inherent trade-off between TSV area and the TSV capacitance during net delay optimization, is also included. Experimental results with GSRC benchmarks show average 25% reduction in TSV footprint for all benchmarks, as compared to the single TSV placement approach. Compared to floorplanning with fixed-sized TSV islands, the approach reduces total chip area by average 7.6% and total interconnect delay by average 9%.

This book was released on 2009-12-02 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in a time of great change. In the electronics world, the last several decades have seen unprecedented growth and advancement, described by Moore’s law. This observation stated that transistor density in integrated circuits doubles every 1. 5–2 years. This came with the simultaneous improvement of individual device perf- mance as well as the reduction of device power such that the total power of the resulting ICs remained under control. No trend remains constant forever, and this is unfortunately the case with Moore’s law. The trouble began a number of years ago when CMOS devices were no longer able to proceed along the classical scaling trends. Key device parameters such as gate oxide thickness were simply no longer able to scale. As a result, device o- state currents began to creep up at an alarming rate. These continuing problems with classical scaling have led to a leveling off of IC clock speeds to the range of several GHz. Of course, chips can be clocked higher but the thermal issues become unmanageable. This has led to the recent trend toward microprocessors with mul- ple cores, each running at a few GHz at the most. The goal is to continue improving performance via parallelism by adding more and more cores instead of increasing speed. The challenge here is to ensure that general purpose codes can be ef?ciently parallelized. There is another potential solution to the problem of how to improve CMOS technology performance: three-dimensional integrated circuits (3D ICs).
