The Frontiers of Robust Circuit Design in Sub-28nm Process Technologies

Presenter:
Jim Dodrill, ARM

Jim Dodrill Jim Dodrill

Summary: The major sources of margining and reliability concerns in integrated circuits are well known. They include timing uncertainty due to process, voltage and temperature variation; aging due to EM, NBTI/PBTI and HCI; and soft errors due to radiation. These concerns tend to increase as process geometries shrink, extreme dynamic voltage scaling is used to push frequencies up or drive power down, and operation across extended temperature ranges is required. Overly conservative design margins, which have been used in the past, have become too costly. EDA software to address these concerns is evolving, but not yet capable of accurately addressing all of them. So what is the state of the art in robust design and how much design margin is enough? This tutorial will attempt to answer those questions for applications ranging from servers to IoT devices using the latest literature and ARM's internal research and analysis.

Powering Microsystems

Presenter:
Prof. Gabriel A. Rincón-Mora , Georgia Tech

Gabriel A. Rincón-Mora Gabriel A. Rincón-Mora

Summary:Wireless microsensors can not only monitor and manage power consumption in small- and large-scale applications for space, military, medical, agricultural, and consumer markets but also add energy-saving and life-saving intelligence to large infrastructures and tiny contraptions in remote and difficult-to-reach places. Ultra-small systems, however, cannot store sufficient energy to sustain monitoring, interface, processing, and telemetry functions for extended periods. And replacing or recharging the batteries of hundreds of networked nodes is prohibitive, and often impossible. This is why fuel cells, atomic batteries, and ambient sources are the subject of ardent research today. Except, power densities are low, and in some cases, intermittent, so these devices cannot power many functions. Plus, tiny lithium-ion batteries and super capacitors, while power dense, cannot sustain life for long. This talk illustrates how tiny fuel cells, batteries, and energy-harvesting generators can power practical microsystems for extended periods. For this, the presentation reviews prevailing system requirements, notes technological constraints, and shows the state of the art in miniaturized energy sources and power supplies.

Reliability Challenges in Sub 20nm Technology

Presenter:
Dr. Tanya Nigam , GLOBALFOUNDRIES

Tanya Nigam Tanya Nigam

Summary: It has been demonstrated that the introduction of HfO2 gate stacks into CMOS technologies provides the means to continue with traditional device gate length scaling. However, the introduction of HfO2 as a new gate dielectric into the gate stack of FETs brings about new challenges for understanding reliability physics and qualification. This tutorial summarizes recent advances in the modeling of charge trapping and defect generation in HfO2 gate stacks. The tutorial relates the electrical properties to the chemical/physical properties of the high-k dielectric and discusses implication for technology scaling. Additionally the reliability challenges with the introduction of new channel materials will be discussed.

Secure Hardware in the Nano Era: Some New Directions

Presenter:
Prof. Swarup Bhunia , Case Western Reserve University

Swarup Bhunia Swarup Bhunia

Summary: Security of electronics is traditionally associated with the security of software, the information being processed, and the network infrastructure. The hardware components, platforms and supply chains are considered secure and trustworthy. However, recent discoveries and reports on diverse security attacks in microchips and circuits violate the hardware root of trust. Protection against these attacks is extremely challenging due to economic issues as well as the sheer complexity of modern electronic hardware. To provide higher levels of assurance and trust to designers, system manufacturers and end users, there is an urgent need to integrate security measures during design and manufacturing test addressing all aspects of security threats. This presentation will cover some emerging solutions in this area. In particular, it will discuss low-overhead protection against counterfeiting attacks, system-on-chip security against side-channel attacks, hardware Trojan detection approaches and a novel paradigm for "design for security" (DfS) based on hardware obfuscation that can protect against malicious modifications as well as piracy. The talk would point to emerging threats and future directions in hardware security research.

Security and Validation in SoC Designs Cooperation, Conflicts, and Trade-offs

Presenter:
Dr. Sandip Ray , Intel Corporation

Sandip Ray Sandip Ray

Summary: Recent years have seen rapid proliferation of System-on-a-Chip (SoC) designs. SoC designs pervade in electronic devices for the embedded and global markets including smartphones, tablets, medical instruments, gaming, automotive, etc. The trend is towards even faster proliferation of these devices in the next decade with newer and more diverse form factors such as wearables and Internet-of-Things. One consequence of this diversity of critical applications is that security of the systems has become a centerpiece of SoC design, architecture, validation, and debug. Secure collaterals in a modern SoC design include secret keys, fuses, cryptographic modules, firmware, etc., and the design architecture includes complex security policies governing access to these collaterals during different phases of the system execution. Security validation in SoC designs entails ensuring both that the design implementation respects these policies, and that the policies themselves ensure the desired overall integrity of the system in the presence of adversaries. The "arms race" between increasing sophistication, diversity, of security attacks on the one hand and resiliency mechanisms in the design on the other, has made security validation a highly critical, complex, challenging, and fun activity. This tutorial will provide an overview of validation techniques for secure collaterals in SoC designs. We will consider security issues both at the level of individual IPs and for an integrated system, validation techniques at the different levels, and tradeoffs and challenges between IP-level and system-level strategies. We will also discuss conflicts and trade-offs between resiliency and validation techniques in the context of security collaterals. Specific examples of industrial validation practices will be discussed.

Neuromorphic Computing based Processors

Presenter:
Prof. Hao Jiang , San Francisco State University

Hao Jiang Hao Jiang

Summary: For implants that interfaces with neurons, a high-efficient miniaturized processor is highly desirable. Memristor based processor has demonstrated its potential to achieve high-efficient processing power with small factor, further, the spike based neuromorphic computing scheme has the potential to exchange information with neuron systems directly, since both systems rely on electrical spikes to deliver information. In such a system, however, the high-speed read and write circuits pose major challenge to its overall efficiency. Dr. Jiang and his students actively look for new circuit architectures to achieve efficient the read and write functions with maximal speed and minimal power and area. These circuits are different from traditional analog circuits because input and output signals swing from 0 to Vdd, also they are different from traditional digital circuits because the spacing time between any two spikes is a critical analog variable in the computation. A new breed of circuits is needed to achieve efficient signal processing with minimal power and size to meet implants' requirements.
