Tutorials at ISCAS 2022
This year a major emphasis has been placed on providing a comprehensive tutorial program for participants of the conference. The tutorial topics are focused primarily on emerging technologies that should be of widespread interests to the CAS Community. Included are eight tutorials on basic and advanced machine learning, a track of four tutorials on vehicular electronics and radiation hard circuits, a track of four tutorials on data converters, and a track of four tutorials on secure integrated circuits and power management.
A total of 20 tutorials will be presented by experts in the field. The tutorials will be given on Sunday May 29th. Each tutorial is scheduled in a 90- minute time slot with two tutorials sessions in the morning and two tutorial sessions in the afternoon. As such, in-person registrants can attend up to four tutorials on Sunday. Recordings will be made of the tutorials so all registrants to the tutorial program will be able to view streams of any of the tutorials for 30 days after the conference is over. A single tutorial registration fee provides access to all tutorials.
The 20 tutorials will be arranged into 5 tracks but participants can move from one track to another throughout the day. A poll will be sent to tutorial registrants in early May to obtain an estimate of how many participants can be expected in each tutorial to help facilitate determining the size of the rooms that will be needed for each tutorial.

Tutorial 1.2 Machine Learning Hardware Design for Efficiency, Flexibility and Scalability
Abstract
Machine learning (ML) is the driving application of the next-generation computational hardware. How to design ML hardware to achieve a high performance, efficiency, and flexibility to support fast growing ML workloads is a key challenge. Besides dataflow-optimized systolic arrays and single instruction, multiple data (SIMD) engines, efficient ML accelerators have been designed to take advantage of static and dynamic data sparsity. To accommodate the fast-evolving ML workloads, matrix engines can be integrated with an FPGA to provide the efficiency of kernel computation and the flexibility of control. To support the increasing ML model complexity, modular chiplets can be tiled on a 2.5D interposer and stacked in a 3D package. We envision that a combination of these techniques will be required to address the needs of future ML applications.

Tutorial 1.3 Compute-in-Memory
Abstract
Compute-in-memory (CIM) is a new paradigm for machine learning hardware acceleration. DNN+NeuroSim is an integrated framework to benchmark CIM accelerators for deep neural network (DNN), with hierarchical design options from device-level, to circuit-level and up to algorithm-level. NeuroSim is a C++ based circuit-level macro model, which can achieve fast early-stage pre-RTL design exploration (compared to a full SPICE simulation). It takes design parameters including memory types (includes SRAM, RRAM, PCM, MRAM and FeFET), non-ideal device parameters, transistor technology nodes (from 130 nm to 7nm), memory array size, training dataset and traces to estimate the area, latency, dynamic energy, leakage power. A python wrapper is developed to interface NeuroSim with deep learning platforms Pytorch, to support flexible network topologies including VGG, DenseNet and ResNet for CIFAR/ImageNet classification. It supports weight/activation/gradient/error quantization in algorithm, and takes non-ideal properties of synaptic devices and peripheral circuits, in order to estimate training/inference accuracy. The framework is open-sourced and publicly available on GitHub https://github.com/neurosim/. NeuroSim’s user community is growing. This tutorial aims for a broader education to the community, and help the researchers to use/modify the code more flexibly for their own research purposes.

Tutorial 1.4 Tiny Machine Learning
Abstract
Modern deep learning requires a massive amount of computational resources, carbon footprint, and engineering efforts. On mobile devices, the hardware resource and power budget are very limited, and on-device machine learning is challenging; retraining the model on-device is even more difficult. We make machine learning efficient and fit tiny devices (TinyML). Our research is highlighted by full-stack optimizations, including the neural network topology, inference library, and the hardware architecture, which allows a larger design space to unearth the underlying principles.

Tutorial 2.2 Mm-Wave Radars Beyond 100 GHz, Neuromorphic Artificial Intelligence and Links to 6G
Abstract
Automotive radar sensors have been at the core of advanced driver assistance systems and represent a reliable perception baseline towards autonomous driving. Giving cars full 360 degree sensing at medium/long range is today possible at acceptable cost due to advances in millimeter-wave CMOS transceivers. Angular resolution is ultimately limited by the number of transmit and receive antennas that can be physically integrated in a given aperture, but also by the amount of data processing that needs to be performed. For these reasons, imec is developing 140 GHz CMOS radar front-ends (smaller antennas), but also on neuromorphic compute architectures and algorithms to address these challenges.
This tutorial covers the technologies that are under development for 140 GHz CMOS radar, which range from analog front-end circuitry to MMIC packaging, interconnect and antennas. We will also cover emerging neuromorphic AI technologies and how they relate to radar. Finally, we will touch on technology developments for 6G above 100 GHz, as these are expected to cross over to radar.

Tutorial 2.3 Large Scale Integration of Analog, Mixed Signal and Power Integrated Circuits for Automotive Applications and Testing Methodology for Quality
Abstract
Power transistors form the main component of automotive Integrated Circuits (ICs) and they handle several amperes of current (>2A). State of the Art is to integrate several power MOSFETs along with their gate drivers (including charge pumps or boost converters that supply the gate drivers) whose operating voltage range is from 5V to 60V. Reliability of these integrated gate drivers and power transistors is a key factor to meet the high-quality demands of the automotive applications. In this tutorial, challenges related to the design and reliability of circuits like LDOs, High Side (HS) drivers, Low Side (LS) drivers and configurable HS/ LS drivers are discussed along with information related to floating nodes, aging and reliability related concerns like NBTI/PBTI, HCI etc. and proven design techniques to simulate and mitigate these challenges. These gate drivers have to be thoroughly designed for robustness w.r.to. Electrical and Thermal Safe Operating Area (SOA) and its test methodology by shorting the outputs to ground and battery will be discussed. In this tutorial, Design FMEA (Failure Mode Effect Analysis) based analysis to mitigate risks at design and system level along with test concepts towards very low dppm (defective parts per million) will be discussed.

Tutorial 2.4 Assessment and Mitigation of Radiation Effects on Circuits and Systems at Different Levels of Abstraction
Abstract:
To reach levels of reliability comparable to those required by high safety standards, it is imperative to supply circuits and electronic computing systems with appropriate mechanisms to reduce their vulnerability to radiation-induced soft errors. In this tutorial, we will discuss the key challenges, benefits, and impediments of assessing and mitigating the soft error reliability of circuits and systems, taking into account different levels of abstraction and approaches, varying from the use of ML to identify a particular source of error (e.g., software or hardware component), circuits techniques, to real laser-induced and neutron radiation experiments. To illustrate the relevance of each soft error assessment and mitigation approach, case studies covering safety-critical systems and resource-constraint IoT devices, applications, libraries/APIs and deep neural network characteristics will be discussed. This tutorial will also present circuitlevelmitigation techniques and a framework that supports fast and early soft error assessment, diagnosis, and susceptibility reduction evaluation by applying different mitigation techniques.

Tutorial 3.1 A Simple and Intuitive Approach to Sensing, Sampling and Quantization
Abstract
This educational session is composed on two parts. In the first part, we will cover the topic of universal sensor design introducing a method for the design of any sensor acquisition chain is anyhow related to a few constraints (time, information, and power consumption). The method will show how framing the design along a few variables can enhance the overall performance and reduce the design time. We will also show how to optimize the segmentation and quantization of the sensing acquisition chain to maximize the resolution and the time response of the overall system.
In the second part, we will dive deeper and try to build an intuitive view of sampling and one-bit quantization on the specific topic of signal-noise interaction. Furthermore, we will see how this more intuitive and simpler view can help addressing problems that for an exact solution would require high-order math (like special functions) and provide approximate solutions which are useful in many applications, like determine the quantizer gain in single-bit delta-sigma converter or dynamic-element matching.

Tutorial 3.2 Non-uniform Sampling ADCs
Abstract
Uniform sampling has been widely adopted in today’s circuit designs, ranging from data converters (ADC and DAC), and discrete-time signal processing (such as switched-capacitor filters). It is a well-developed processing technique that leads to many circuit architectures. However, Nyquist theory does not limit us to processing the samples at a uniform time grid so long as the average sample rate is sufficiently high, i.e., no loss of signal information. We refer data converters that sample at irregular time instants as non-uniform sampling (NUS) ADCs. In this tutorial, we will overview the basics of non-uniform sampling and the design tradeoffs for such ADC architecture. We will also examine several possible variations of NUS ADCs, and experimental results of silicon prototypes. Thanks to the unique properties of NUS, there are interesting possibilities for future circuit- and system-level architectural innovations.

Tutorial 3.3 Precision Continuous-Time Delta-Sigma Data Converters
Abstract
Precision delta-sigma converters (i.e those that achieve 16+ bits resolutions over more than 10x the audio bandwidth) have typically been realized using discrete-time circuitry. This talk motivates the use of continuous-time delta-sigma modulation in such applications. Power-efficient, high-resolution continuous-time delta-sigma modulators need to consider several effects (some second-order, and others not-so-second-order) that might seem harmless in converters that attempt a more modest in-band noise spectral density. Examples of such effects include flicker noise, layout-routing resistance and DAC inter-symbol-interference. This talk aims to give insights into these effects and describe techniques that address the formidable challenge of designing such converters. A practical design example will be used to place things in perspective. It will also demonstrate that these techniques can be readily applied to higher speed designs.

Tutorial 3.4 Noise-Shaping SAR ADCs
Abstract
SAR is widely used for medium resolution applications due to its simplicity, scaling compatibility, and low-power consumption. However, its power efficiency degrades as the resolution increases due to its tight requirement on the comparator noise and the exponentially growing capacitor DAC array. By contrast, DS ADC is a popular architecture for high-resolution applications. Taking advantage of noise shaping, it can achieve high resolution with a low-resolution quantizer and DAC. However, it typically requires the use of op-amps that are power hungry and scaling unfriendly. This talk will present latest noise-shaping (NS) SAR ADCs that aim to combine the merits of SAR and DS ADCs while simultaneously obviating their drawbacks. It includes both cascade of integrators with feed-forward (CIFF) and error-feedback (EF) NS-SAR architectures. It covers various types of hardware implementations, including both active and passive loop filters and adders. It also discusses interesting extensions of NS-SAR ADCs, including time-interleaved NS-SAR and continuous-time (CT) DS ADC with NS-SAR quantizer.

Tutorial 4.1 Advances in Cross-Domain Image Compression
Abstract
In this tutorial, we will introduce the recent progress in generative image compression, which targets on learning a compression model effeciently storing images with low bitrates while producing perceptually high-fieldlity reconstructions. It has drawn increasing attention and made tremendous development in recent years because of better perceptual quality than traditional image compression algorithms at equal bitrates. We therefore conduct this tutorial of the analysis, methodology, and related applications of generative image compression to clarify the main progress the community has made. Specifically, we first briefly introduce the two most representative generative models, variational autoencoders (VAEs) and generative adversarial networks (GANs), applied for generative image compression. Second, we explore the developing area of generative image compression, including existing methods and potiential directions. In summary, our tutorial will cover latest works and the progress in community, which will help the audiences with different backgrounds better understand the recent progresses in this emerging research area.

Tutorial 4.3 Neuromorphic Spiking Sensors, Network Accelerators, Non-volatile Memory Devices for Low-Power Edge Applications - Part I
Abstract
Neuromorphic spiking sensors including the event-driven Dynamic Audio Sensor (DAS) and Dynamic Vision Sensor (DVS) event camera are inspired by the functionality of the biological retina and cochlea equivalents. The asynchronous outputs of these event-driven sensors can enable always-on sensing at possible low-latency system-level response time than conventional sampled sensors for Internet of Things (IoT) and Brain-Machine Interface (BMI) applications. Recent developments in deep networks, spiking networks, analog and in-memory computing and non-volatile novel memory devices have led to very low-power neuromorphic systems that combine these sensors and networks for these application domains. Through supervised and unsupervised learning methods from deep learning and neuroscience fields, we show configurations of these systems and equivalent hardware to achieve high accuracy and low latency on benchmark tasks. The novel memory devices help to reduce power from off-chip memory access and can additionally, support different learning algorithms useful for adaptive neuromorphic systems. Analog In-memory computing methods reduce energy required to implement matrix multiplies, nonlinearities and other signal-processing operations over digital systems

Tutorial 4.4 : Neuromorphic Spiking Sensors, Network Accelerators, Non-volatile Memory Devices for Low-Power Edge Applications - Part II
Abstract
A hallmark of brain-inspired computing is the intricately intermixed memory and compute architecture that strongly contrasts with conventional von Neumann ones with memory separated from computing elements. Digital processing element array architectures partially resolve this issue. An even more radical shift is offered by the In-memory computing (IMC) architectures where processing is performed entirely within the memory array with only the results being readout.
This tutorial will discuss two broad types of IMC based on Non-volatile and volatile memories. Analog computing techniques for accelerating matrix-vector multiplications using non-volatile RRAM will be the focus in the first half of the tutorial. The second half will deal with SRAM based in-memory image processing for dynamic vision sensors (DVS) event cameras and discuss particular case studies of traffic monitoring for the internet of video things.

Tutorial 5.1 IC Security and Assurance Module: Mixed-Signal Approaches to IC Security
Abstract
Electronic counterfeiting is a longstanding problem with nontrivial impacts in many sectors. The sale of counterfeits results in substantial economic losses to the electronics industry, reportedly as high as$169B annually. To address these issues, in the last decade and so a large amount of research has been done to secure hardware. Security features such as physically unclonable function (PUF), hardware metering, and obfuscation have been developed to protect hardware from threats. Detection and avoidance techniques for IC counterfeiting and hardware Trojan have been introduced to protect the IC supply chain. Till now, most of the research has focused on digital techniques to tackle these challenges. In this talk, I will present several analog/mixed-signal approaches to IC security, including PUFs and camouflaged gates for IP protection which at their core, leverage analog mixed-signal techniques.
In this module, we will cover (1) IP protection using Physically Unclonable Functions (PUFs); (2) Performance merits of PUFs (3) design challenges and noise vs entropy (4) passive and active entropy sources (5) approaches to leverage new sources of entropy such as passive layers in silicon including metals and Vias, and active elements such as gate leakage (6) using positive feedback for Bimodal distribution to improve the bit error rate and stability; (7) Digital IP protection using camouflage gates (8) overhead and cost associated with the IP protection; (9) challenges to camouflage digital IPs at system level.

Tutorial 5.2 Counterfeit IC Detection and Avoidance
Abstract
Counterfeit electronic components are electronic parts that are misrepresented in terms of their authenticity, class, and/or quality. Due to their substandard specifications and quality, they represent a significant danger if incorporated into safety- and mission-critical systems such as military/defense, space and aircraft navigation, life support, etc. Counterfeit electronics can also infringe the legitimate producer's trademark rights, impact the market reputation of semiconductor and electronics companies, harm the world economy, and finance criminals. Reports of counterfeits have grown over the last several decades because of critical infrastructure’s reliance on commercial-off-the-shelf (COTS) components and obsolete components as well as the rate at which electronics are being discarded. Unfortunately, this problem has shown no signs of slowing down. In fact, experts have warned that counterfeit electronics will be exacerbated by the reduction in precious metal imports and the pandemic-induced chip shortage.
In this module, we will cover (1) Counterfeit electronic part sources, motivation, and risks; (2) Counterfeit IC type taxonomy (recycled, remarked, overproduced, cloned, etc.); (3) Counterfeit defect taxonomy (procedural, mechanical, environmental, and electrical); (4) Counterfeit detection taxonomy (physical, electrical, design-for-anti-counterfeit; (5) Basic parametric/functional tests for counterfeit component detection; (6) More advanced detection approaches that explicitly target counterfeit SoCs, memories (SRAM, DRAM, and Flash), field programmable gate arrays (FPGAs), and AMS ICs; (7) Design-for-anti-counterfeit primitives such as physical unclonable functions (PUFs) and silicon odometers, and their benefits; (8) International standards and commercially available tools; (9) Barriers to the adoption of counterfeit detection tests and avoidance circuits; and (10) Future directions in research, infrastructure, standards, and policy-making to improve the accuracy, cost, scalability, and adoption of counterfeit mitigation techniques.

Tutorial 5.3 How to Stabilize and Control DC–DC Switched-Inductor Power Supplies, Part 1
Tutorial 5.4 How to Stabilize and Control DC–DC Switched-Inductor Power Supplies, Part 2
Abstract
Switched-inductor dc–dc power supplies are pervasive in consumer electronics: in cellular phones, tablets, laptops, chargers, cars, and so on. This is because these voltage regulators supply loads at steady voltages without losing much of the power they draw. Unfortunately, controlling them is a challenge. They close analog feedback loops that switch an inductor into a load with digital signals. Engineers connect a capacitor across this load to supply the dynamic power the inductor cannot provide. This capacitor is small in modern consumer applications, so it cannot supply much power without drooping the output too much. So in addition to managing the mixed-signal complexities of a switched loop, the system needs to respond quickly (with high bandwidth) and reliably (stable feedback operation) to variations in load and the input that supplies the system. This tutorial explains how voltage- and current-mode loops control and stabilize these switching dc–dc converters. With this understanding in mind, the material shows how pulse-width-modulated (PWM), hysteretic, and constant-time peak/valley loops switch the inductor, offset the output, and respond to load and input variations. While some of these concepts can be found in literature, they are largely abstract and algebraic, incomplete, and usually spread over several sources. This presentation, on the other hand, is concise, complete, and full of design insight.
