Until now, there has been a lack of a complete knowledge base to fully comprehend Low power (LP) design and power aware (PA) verification techniques and methodologies and deploy them all together in a real design verification and implementation project. This book is a first approach to establishing a comprehensive PA knowledge base. LP design, PA verification, and Unified Power Format (UPF) or IEEE-1801 power format standards are no longer special features. These technologies and methodologies are now part of industry-standard design, verification, and implementation flows (DVIF). Almost every chip design today incorporates some kind of low power technique either through power management on chip, by dividing the design into different voltage areas and controlling the voltages, through PA dynamic and PA static verification, or their combination. The entire LP design and PA verification process involves thousands of techniques, tools, and methodologies, employed from the r egister transfer level (RTL) of design abstraction down to the synthesis or place-and-route levels of physical design. These techniques, tools, and methodologies are evolving everyday through the progression of design-verification complexity and more intelligent ways of handling that complexity by engineers, researchers, and corporate engineering policy makers.

According to Moore's law, the number of transistors on integrated circuits (ICs) double approximately every two years. Over the years, this growth in number of transistors has reached to billions of transistors per IC, operating at very high frequencies. However, there are many factors limiting this growth rate including power consumption of high-density high-speed integrated circuits. Various techniques have evolved offering reduction in dynamic power consumption and leakage power. Traditional methods like use of power efficient circuits, parallelism in micro-architectures, along with nontraditional methods such as clock gating, variable supply voltage and frequency scaling are becoming significantly important in lowering dynamic power consumption. The leakage power, which has become more significant in the recent high-density designs, can be reduced by minimizing usage of low threshold voltage cells, adding power gating, back biasing, reducing oxide thickness, and using new devices such as FINFET's. Design engineers have to consider clock and power gating techniques up front in the design cycle in today's multi-threshold, multi-oxide, multi-voltage and multi-clock devices. Understanding and implementing power intent at register transfer level (RTL), netlist and PG netlist stages requires additional design verification efforts. In this project, several power reduction and management techniques were studied and applied to an existing System on Chip (SoC) system consisting of an ARM processor, an Ethernet controller, and a DDR controller. Clock and Multi VDD power gating were considered as primary techniques for achieving power reduction. Power intent was created as per the IEEE 1801-2009 Unified Power Format standard. Open source Verilog model of the SoC ARM processor was used as a reference model, along with Synopsys® 90 nm cell library. Synopsys® Electronic Design Automation (EDA) tools were utilized in carrying out simulation, synthesis, and power analysis phases of the project. In addition to implementation of low-power RTL design techniques, use of clock gating, power gating, multi-voltage design partition and multi-threshold voltage cells showed significant improvement in power consumption of the System on Chip (SoC) system used in this work. By considering design issues and verification requirements of these techniques, we developed a power-aware SoC design flow. This enhanced methodology presents a unique approach for effectively incorporating low-power techniques early in the design phase.

Sealed Lead Acid...Nickel Cadmium...Lithium Ion... How do you balance battery life with performance and cost? This book shows you how! Now that "mobile" has become the standard, the consumer not only expects mobility but demands power longevity in wireless devices. As more and more features, computing power, and memory are packed into mobile devices such as iPods, cell phones, and cameras, there is a large and growing gap between what devices can do and the amount of energy engineers can deliver. In fact, the main limiting factor in many portable designs is not hardware or software, but instead how much power can be delivered to the device. This book describes various design approaches to reduce the amount of power a circuit consumes and techniques to effectively manage the available power. Power Management Advice On: •Low Power Packaging Techniques •Power and Clock Gating •Energy Efficient Compilers •Various Display Technologies •Linear vs. Switched Regulators •Software Techniques and Intelligent Algorithms * Addresses power versus performance that each newly developed mobile device faces * Robust case studies drawn from the author's 30 plus years of extensive real world experience are included * Both hardware and software are discussed concerning their roles in power

Introduction The purpose of this book is to provide insight and intuition into the analog and analog-mixed signal system verification. It is also a journey the author of this book has been through on the way to tackle practical design and verification challenges with state of art analog and mixed signal designs. Motivation for authoring this book The digital design verification skill set is very different than analog design and verification. Traditionally, the analog block level verification is performed by the analog designers, and digital design verification is performed by digital design verification engineer. Lack of cross domain skill set makes it challenging to perform verification at mixed-signal level. Hence, either analog designer engineer should learn advanced digital verification techniques or digital design verification engineer embrace analog verification to become analog-mixed signal verification engineer. This book is written keeping this new trend in mind, hence it covers digital design fundamentals, digital design verification as well as analog design fundamentals, and analog performance verification. Organization of this book Keeping the readers of analog verification or digital design verification background in mind, the book has first 5 chapters focused on the fundamentals of the analog design, digital design, and its verification. Chapter 6 and chapter 7 focuses on the analog-mixed signal design verification and behavioral modeling respectively. Chapter 8 is dedicated to the low power verification techniques. Chapter 1: Introduction to Analog Mixed Signal Verification This chapter discusses about the evolution of the verification methodologies, history of analog-mixed signal designs, applications, and future trends. Chapter 2: Analog Design Fundamentals The purpose of this chapter is to give an overview of the analog design fundamentals for digital design background engineers. Major focus is given on analog behavior, design criteria and their concept rather than design themselves, such as voltage/current reference, some of the basic key analog design properties such as gain, band width, basics of jitter, eye diagram, etc. Chapter 3: Digital Design Fundamentals In this chapter, we explain digital design flow, combinational and sequential logic design fundamentals, design for testability, concepts of timing, and timing verification. Chapter 4: Analog Verification This chapter focuses on analog performance verification and functional verification under the context of mixed signal design hierarchical verification rather than the detail performance analysis of the designs themselves. Chapter 5: Digital Design Verification This chapter explains the tools and methodologies that are evolved over the period that are predicated on predictable quality and verification efficiency. The chapter contains the sections on the coverage driven verification (CDV) methodology, assertion based verification (ABV) methodology, and overview of the CDV using Open Verification Methodology (OVM). Chapter 6: Analog-Mixed Signal Verification This chapter discusses about the AMS verification phases, choosing the right abstraction of DUT for a given verification challenge, AMS verification planning, testplanning for AMS design verification, and testbench development with re-use in mind. Chapter 7: Analog Behavioral Modeling This chapter explains about the applications of analog behavioral models, modeling methodology, simple examples of various analog behavioral modeling styles, selection of accuracy level of the models based on the verification plan, model verification, and signoff. Chapter 8: Low Power Verification The purpose of this chapter is to explain the low power design verification challenges, key low power design elements, low power design techniques, low power design and verification cycle, testplanning for low power design verification, power aware digital, and AMS simulations.

Power consumption becomes the most important design goal in a wide range of electronic systems. There are two driving forces towards this trend: continuing device scaling and ever increasing demand of higher computing power. First, device scaling continues to satisfy Moore’s law via a conventional way of scaling (More Moore) and a new way of exploiting the vertical integration (More than Moore). Second, mobile and IT convergence requires more computing power on the silicon chip than ever. Cell phones are now evolving towards mobile PC. PCs and data centers are becoming commodities in house and a must in industry. Both supply enabled by device scaling and demand triggered by the convergence trend realize more computation on chip (via multi-core, integration of diverse functionalities on mobile SoCs, etc.) and finally more power consumption incurring power-related issues and constraints. Energy-Aware System Design: Algorithms and Architectures provides state-of-the-art ideas for low power design methods from circuit, architecture to software level and offers design case studies in three fast growing areas of mobile storage, biomedical and security. Important topics and features: - Describes very recent advanced issues and methods for energy-aware design at each design level from circuit and architecture to algorithm level, and also covering important blocks including low power main memory subsystem and on-chip network at architecture level - Explains efficient power conversion and delivery which is becoming important as heterogeneous power sources are adopted for digital and non-digital parts - Investigates 3D die stacking emphasizing temperature awareness for better perspective on energy efficiency - Presents three practical energy-aware design case studies; novel storage device (e.g., solid state disk), biomedical electronics (e.g., cochlear and retina implants), and wireless surveillance camera systems. Researchers and engineers in the field of hardware and software design will find this book an excellent starting point to catch up with the state-of-the-art ideas of low power design.

This book pioneers the field of gain-cell embedded DRAM (GC-eDRAM) design for low-power VLSI systems-on-chip (SoCs). Novel GC-eDRAMs are specifically designed and optimized for a range of low-power VLSI SoCs, ranging from ultra-low power to power-aware high-performance applications. After a detailed review of prior-art GC-eDRAMs, an analytical retention time distribution model is introduced and validated by silicon measurements, which is key for low-power GC-eDRAM design. The book then investigates supply voltage scaling and near-threshold voltage (NTV) operation of a conventional gain cell (GC), before presenting novel GC circuit and assist techniques for NTV operation, including a 3-transistor full transmission-gate write port, reverse body biasing (RBB), and a replica technique for optimum refresh timing. Next, conventional GC bitcells are evaluated under aggressive technology and voltage scaling (down to the subthreshold domain), before novel bitcells for aggressively scaled CMOS nodes and soft-error tolerance as presented, including a 4-transistor GC with partial internal feedback and a 4-transistor GC with built-in redundancy.
