Ultra-Low-Voltage (ULV) IC Design: Designing for VDD below kT/q

Márcio Cherem Schneider
Universidade Federal de Santa Catarina - UFSC, Brazil
September 1st, Tuesday, 10:40 to 12:20

Abstract: The main solution to reduce the energy consumption of electronic circuits is to lower the supply voltage. This tutorial presents fundamentals for the design of MOS circuits that can operate at very low supply voltages. Operation of the MOS transistor in weak inversion is highlighted owing to the limited voltages available. CMOS logic gates and the Schmitt Trigger circuit in weak inversion are analyzed. Special attention has been given to the properties of the zero-VT transistor due to its high drive capability at low voltages. Ultra-low-voltage rectifiers using diode-connected zero-VT MOSFETs operating in weak inversion are included in the presentation. Elementary amplifiers at ultra-low-voltage are reviewed. Inductive-load oscillator prototypes built in 130 nm technology demonstrate that oscillators can operate at supply voltages below the thermal voltage kT/q.

Abstract: The Modeling and characterization of low-frequency noise and noise variability in various regimes of operation are investigated for the main advanced CMOS technologies. Novel materials and innovative device architectures from 0.5µm to 20nm gate lengths are studied. The impact of gate stack, realized with ultrathin oxides, polysilicon gate and high k/metal gate is analyzed. The influence of alternative channel materials, in particular ultrathin body Silicon-On-Insulator layers, strain Si and III-V materials is addressed. The comparison of low frequency noise in advanced device architectures, including Bulk Si, Fully-Depleted SOI, FinFET, Junctionless, and Multi-gates structures, is shown. Accurate noise models, taking into account the main physical mechanisms, are proposed for all these very advanced technologies, which will be needed for the Nanoelectronics of the next decade.

3D ICs - Moving from Silicon to Heterogeneous Technologies

Maciej Ogorzalek
Jagiellonian University, Krakow, Poland
September 1st, Tuesday, 13:40 to 15:20

Abstract: 3D integration has been proposed in recent years to overcome serious limitations in routing-connection length, power limitations and technology limits in terms of chip area and yield. The 3D technologies in silicon have reached the stage of being sufficiently ripe to move to industrial applications - hybrid memory cube, advanced FPGA chips are good examples of multilayer chips employing advanced silicon technologies. Simultaneously to development of 3D techniques one can observe extensive effort to bring into the picture new competitive devices and circuits developed using new non-silicon technologies. Various types of memories (RRAM, Spintronic), optical, chemical or bio-medical sensors, energy scavengers and energy storage elements have been developed and investigated. Possibility of integration of building blocks realized in diverse technologies is the next step we are facing, bringing new interesting concepts and new challenges. The “Much-more-then-Moore” direction brings many promises for new circuitry and new systems on chip with parameters far exceeding currently available CMOS.

Cyber - Physical Systems: Reality, Dreams, and Fantasy

Magdy A. Bayoumi
University of Louisiana at Lafayette, EUA
September 1st, Tuesday, 15:40 to 17:20

Abstract: The integration of physical systems with networked sensing, computation networks, and embedded control with actuation has led to the emergence of a new generation of engineered systems, the Cyber-Physical Systems (CPS). Such systems emphasize the link between cyber space and physical environment (i.e., time, space, and energy). CPS represents the next generation of complex engineering systems. They are large scale dynamic systems that offer significant processing power while interacting across communication networks. CPS will help to solve the grand challenges of our society, such as, aging population, limited resources, sustainability, environment, mobility, security, health care, etc. Applications of CPS cover a wide band of economic, medical, and entertainment sectors. It includes; Transportation: automobiles, avionics, unmanned vehicles and smart roads; Large Scale Critical Infrastructure: bridges, mega buildings, power grid, defense systems; Health Care: medical devices, health management networks, telemedicine; Consumer Electronics: video games, audio/video processing, and mobile communication. Building Cyber-Physical Systems is not a trivial task. The difficulty arises from the existing gap in modeling and computing of the physical and cyber environments. The design process requires new theories, models, and algorithms that unify both environments in one framework. None of the current state-of-the art methods are able to overcome the challenges of developing the unified CPS design paradigm. Several of these issues will be discussed in this talk. Case studies of real world CPSs will be illustrated.

Low Loss, High Isolation, Linear RF Switch Design in SOI

Peter H. Popplewell
Skyworks Solutions, Canada
September 1st, Tuesday, 15:40 to 17:20

Abstract: The tremendous popularity in recent years of wireless connected devices, especially those containing multi-band capable radios, or those making use of antenna tuning or antenna diversity has led to widespread demand of high quality RF switch circuits. Requirements range from simple single-pole double-throw (SP2T) with single-bit control interfaces, to upwards of 20-throw switches with mipi digital interfaces and on-die logic decoding. Insertion loss requirements below 0.5dB at RF frequencies are common, with isolation between RF ports of 30 dB or better being achievable. Cellular applications can require switches tolerant of over +35 dBm of signal power, often with additional robustness required to handle VSWR conditions under mismatch. This tutorial discusses the suitability of SOI technology at addressing many of these challenging requirements. SOI has excellent RF properties, high voltage tolerance for stacked devices, and the ability to integrate common CMOS circuits for the purpose of supporting and optimizing the RF functions of a switch die. Switch biasing schemes and their tradeoffs are discussed, along with the fundamentals of RF switch design in SOI, designing for high voltage tolerance, low vs. high band insertion loss, optimal isolation, ESD protection, and linearity. Analog support circuits such as negative-voltage generators are introduced, as well as practical layout strategies for minimizing noise and switch loss. The Ron/Coff figure of merit is discussed, as well as flip-chip, WLCSP and wire bonded packaging options and their associated effects on performance.

Frame Free Vision

Teresa Serrano-Gotarredona
IMSECNM-CSIC, Sevilla; University of Sevilla, Spain
September 2nd, Wednesday, 13:20 to 14:00

Abstract: State of the art in artificial vision is based on video streams, by capturing sequences of images at a given "frame rate" and processing them frame after frame by computational algorithms. On the other hand, biological vision is frame-free: neither the eyes nor the brain have a clue of what a video frame is. In biology, retina cells (pixels) send electric spikes (also called "events") asynchronously to the brain through the optical nerve fibers. Cells in the brain process these spikes through complex hierarchical structures to achieve, for example, shape size and pose invariant object recognition. There are no frames, but just a continuous flow of spikes/events from the retina through the cortical brain structures. Recently, several groups worldwide are developing bioinspired vision sensors and processors where the visual information is not represented as a sequence of frames but as a continuous flow of events or spikes. This asynchronous frame-free sensing and processing paradigm is also called "event-driven" (as opposed to "frame-driven"). New event-driven vision sensor chips sensitive to temporal changes in the visual scene (also called Dynamic Vision Sensor or DVS) together with event-driven convolution module arrays implemented on chip or using high-end FPGAs will be presented. Finally examples on how by modularly interconnecting event-driven sensors and processors complex real-time recognition systems can be assembled will be shown.

Majority-based Synthesis for Digital Nano-technologies

Giovanni de Micheli
EPFL, Switzerland
September 3rd, Thursday, 08:40 to 09:40

Abstract: Logic synthesis/optimization algorithms and tools have been used for over three decades. Still they suffer from various weaknesses, because they were conceived with CMOS AOI static gates in mind, with more primitive computers and storage systems, and without a strong formal basis. The design of large-scale, computation oriented, digital circuits is still a main challenge even with state of the art commercial tools. Because of the convergence of fabrication technologies, the competitive edge in CMOS design resides in its logic-level structuring achieved within synthesis. Moreover, novel nano technologies open new horizons by means of logic gates with enhanced functionality. Thus, more than ever, synthesis technology is a key to exploit technology in the search for the best design. This talk shows the motivation for searching better models and algorithms - as compared to the state of the art - for logic synthesis. A new Boolean algebra and model is shown to be effective for digital circuit optimization for speed, area and power consumption. Experimental results show that the new tool, MIGHTY, outperforms a commercial tool on the three metrics after complete physical design.

System-Level Design of Heterogeneous System-on-Chip Architectures

Luca Carloni
Columbia University, EUA
September 3rd, Thursday, 13:20 to 14:00

Abstract: The heterogeneous multi-core system-on-chip, which combines programmable processors and specialized hardware accelerators, is emerging as a dominant platform architecture across many computing domains, from mobile devices to data centers. Accelerators offer an effective design solution in the face of tight power budgets because they provide energy-efficient performance for critical computation kernels and are activated via software only when needed. The presence of many accelerators, however, increases design heterogeneity, which in turn exacerbates system complexity and prolongs design time. To address these challenges I present a design methodology that raises the level of abstraction to the system level, simplifies the integration of heterogeneous components, and leverages recent results on supervised design-space exploration for component reuse. I illustrate the effectiveness of this approach by describing its application to the design of complex system-on-chip prototypes with both FPGA and ASIC technologies.

A Path towards Average-Case Silicon via Asynchronous Resilient Bundled-Data Design

Peter Beerel
University of Southern California (USC) in Los Angeles, EUA
September 4th, Friday, 08:40 to 09:40

Abstract: The periodic nature of the global clock in traditional synchronous designs forces circuits to be margined for the worst possible case of process, voltage, temperature, and data conditions. This constrains the silicon to operate at worst-case frequencies and at conservative supply voltages. Resilient architectures promise to remove these margins, by detecting and correcting timing errors when they occur, thereby creating the potential to achieve real average-case operation. However, synchronous resilient schemes previously proposed can suffer from multiple issues, including being susceptible to metastability and requiring complex changes to the architecture to support replay-based recovery from timing errors. These problems respectively lead to circuit failures and/or incur high timing penalties when errors occur. This keynote explores how the research to achieve average-case silicon evolved over the last two decades. Particularly, it discusses a recently proposed asynchronous bundled-data resilient template called Blade that is robust to metastability issues, requires no replay-based logic, and has low timing error penalties. The Author describes some open issues and new research opportunities this template presents, including automation problems to target average-case operation, specific circuit optimizations to minimize resiliency overhead, and the need for new test procedures to tune delay lines and screen out bad chips.

Rethinking "Things" Design - The Missing Technology Link in the Internet of Things (IoT)

Massimo Alioto
National Univ. of Singapore
September 4th, Friday, 13:20 to 14:00

Abstract: The Internet of Things (IoT) has now become a main driver in research and next-generation technology development, and is expected to foster the growth of the semiconductor industry in the next decade or more, once the wave of mobile platforms reaches its peak. In spite of daily announcements of new industrial projects in the IoT domain, the physical nodes that gather sensed data (the “things”) are still technologically immature, and well behind the rest of the IoT infrastructure. This lag has been determined by several daunting challenges in terms of energy efficiency and security under tight cost constraints, as well as a rigid view on the quality of service provided by IoT nodes. Energy efficiency is indeed synonym for node availability and size, whereas cheap chip-level security is a necessary premise to build adequate trust in the minds of potential adopters.
This keynote speech addresses these fundamental issues and sketches a map to move towards the true realization of the physical layer of IoT, and ultimately enable IoT nodes with extreme energy efficiency and unceasing security, in both space (across nodes) and time (in each node). The scalable quality of service in IoT nodes is shown to be a key ingredient to relax the critical design tradeoffs, and generalize the well-known concept of “QoS” that is ubiquitously applied in the Internet of today. A perspective is finally given on the future role of technology and EDA industry in the IoT arena, based on the natural bottom-up (business) pressure that has made the Internet possible in the past. And will make the Internet of Things real in the future.
