poster

 Electronic design and design automation (EDA) is a key enabling technology in the advancement of information processing that we are enjoying today. EDA has provided fundamental design principles and tools empowering the exponential growth of the number of transistors on an integrated circuit chip over the past 50 years. Without EDA, it would not have been possible for billion-transistor chips to be a reality! 

After five decades of growth, the field of EDA now faces some unique challenges. On one hand, we are approaching the physical limit of transistor scaling, and the golden days of exponential growth in transistor density are over. The exorbitant cost of integrated circuit fabrication and the excessive complexity of EDA tools make it difficult to bring design automation innovations to practice. On the other hand, the recent rise of machine learning and artificial intelligence applications and emerging architectures and technologies calls for more customized solutions to designing electronic systems. 

## **Objectives of the Workshop:**

This workshop, funded by the National Science Foundation (NSF), will assemble a diverse group of leading researchers from both academia and industry to identify future research directions in design and design automation of electronic systems and architectures in response to the challenges and opportunities. It will feature plenary talks and panels as well as roundtable discussions. Collectively, the workshop attendees will explore answers to overarching questions such as 

•	what are the high-risk and high-return research topics, 

•	what other fields adjacent to EDA research should be aggressively pursued for highly interdisciplinary collaboration, and

•	where the research funding should come from and how it should be distributed to encourage more transformative research. 

The workshop will also include a satellite event with a roundtable panel discussion on strategies to improve foundry access to US-based EDA researchers. A final report, based on the deliberations of the workshop, will be produced to the government recommending future research directions.


As Moore's law stalls, novel computing solutions are urgently needed to meet the ever-increasing computing demands from emerging applications such as modern machine learning tasks. With digital techniques running out of steam and emerging technologies pending material revolution, mixed-signal computing which combines circuit techniques in digital, analog, and time domains bring significant opportunities in the near future to dramatically improve computing efficiency.  The benefits of mixed-signal computing include high energy efficiency, compatibility with existing CMOS technology and EDA tools, and strong ties to physical world in a near-sensor or IoT environment.  In this poster, we will briefly discuss the concepts and examples of leveraging the dimensions of “time” in mixed-signal design to accelerate the computing tasks in emerging applications.

Mixed-signal Computing for Emerging Applications

In-memory computing (IMC) SRAM has been demonstrated as a promising technique to significantly improve energy-efficiency for deep neural network (DNN) hardware accelerators. However, designing one involves setting many design variables such as the number of parallel rows to simultaneously activate, analog-to-digital converter (ADC) resolution at the periphery of a memory sub-array, precisions of various parts of a DNN model, etc., which affect energy-efficiency, accuracy, and area. Prior works have not investigated this multi-dimensional design optimization. To fill this knowledge gap, we present an SRAM-based IMC hardware modeling and optimization framework.

Voltage control of nanoscale magnetism: For energy efficient memory and neuromorphic computing

This poster presents our work on rapid simulation and automated design of silicon photonics devices funded by the NSF under a CRII grant. Silicon Photonics is an exciting emerging technology platform which leverages existing CMOS Silicon-on-Insulator foundry infrastructure to guide and manipulate light on the nanoscale. Despite having great potential, silicon photonic devices are challenging to design and simulate due to the lack of analytical solutions, small wavelengths, and large structures involved. Simulations today rely on the Finite-Difference Time-Domain (FDTD) method. Unfortunately, FDTD suffers from slow convergence, poor accuracy, long simulation times, and significant numerical dispersion. The goals of this project are to couple a fast simulation method with optimization techniques to achieve rapid automated design of silicon photonics devices. To achieve this, we propose an alternative simulation approach which is based on boundary integral equations (BIE) in the frequency-domain. Our method is dispersion-free and only requires discretization of the material interfaces which reduces the number of unknowns significantly. The method is high-order accurate, achieving close to spectral accuracy, and only requires meshing at a few points per wavelength. Our poster introduces our BIE algorithms and implementations in both two and three dimensions and demonstrates recent results using our framework to rapidly simulate silicon photonic devices with high accuracy. We also demonstrate fast automated design of new, high-performance silicon photonic devices in both 2D and 3D by applying the adjoint method for computing the gradient of the objective function used for optimization. We have fabricated several of the devices optimized via our methodology and are currently in the process of measuring them to compare against our predicted simulation results.

CRII: SHF: Ultra-fast Simulation and Automated Design of Silicon Photonics Devices

Associative Processing (AP) is a promising alternative to the Von Neumann model as it addresses the memory wall problem through its inherent in-memory computations. However, because of the countless design parameter choices, comparisons between implementations of two so radically different models are challenging for simulation-based methods. To tackle these challenges, we develop an alternative analytical approach based on a new concept called architecturally-determined complexity. Using this method, we asymptotically evaluate the runtime/storage/energy bounds of the two models, i.e., AP and Von Neumann. We further apply the method to gain more insights into the performance bottlenecks of traditional AP and develop a new machine model named Two Dimensional AP to address these limitations.

CAREER: Associative In-Memory Graph Processing Paradigm: Towards Tera-TEPS Graph Traversal In a Box

With the advent of Internet-of-Things and the necessity to enable intelligence in embedded devices like mobile phones, smart watches etc., low-power and secure hardware implementation of neural networks is vital. Despite achieving super-human performance and classification accuracies on a variety of perception tasks, Deep Neural Networks (DNNs) have been shown to be adversarially vulnerable.  A DNN can be easily fooled into misclassifying an input with slight changes of pixel intensities. This vulnerability severely limits the deployment and potential safe-use of DNNs for real world applications such as self-driving cars, malware detection, healthcare monitoring systems etc. This poster investigates hardware aware optimization techniques to potentially resolve or resist software vulnerabilities (specifically, adversarial attacks). It aims to explore the design space of energy-accuracy-robustness trade-ff cohesively with algorithm-hardware co-design to create truly functional intelligent systems. This poster demonstrates robustness aware algorithms broadly applicable to the energy-efficient and secure implementation of DNN engines on both current complementary metal oxide semiconductor (CMOS) accelerator platforms and emerging memory technologies (with analog crossbar dot-product engines).

Electrical-Thermal Co-Design of 2.5D/3D ICs

While the proliferation of electronics has been driven by computing and consumer applications for a long time, integrated circuits (ICs) presently undergo accelerated integration into healthcare, transportation, robotics, and autonomous systems. In addition to provision of prescribed functionalities of sensing, computing, and processing, these ICs must meet stringent reliability specifications in order to safeguard performance and safety of the whole mission-critical system where deployed. Circuits designed to be fail-safe by design exhibit low occurrences of failure. However, having a sign of no failure under typical verification and test procedures yields no guarantee for meeting a given near-zero or extremely-low failure specification. On the other hand, exhaustiveness may never be achieved by brute-force failure detection, which results in an unacceptably high cost in simulation and testing. This project will develop efficient machine-learning techniques for extremely-rare circuit-failure detection without needing large amounts of expensive simulation or test data. The proposed techniques will enable cost-effective verification and test of reliability-critical ICs and mission-critical systems in general. The research undertaken will also enable the two groups at UC Santa Barbara and UT Dallas to educate and train undergraduate and graduate students, including women and underrepresented groups, thus expanding the and contributing to the much needed US technological workforce.

It is believed that extracting critical failure information via machine learning within practical limits of available measurement or simulation data can go a long way towards extremely rare failure detection. This project centers on developing an active-learning framework that intelligently samples in the high-dimensional space of complex interacting design parameters, manufacturing variations, and operating conditions, achieving the goal of data-efficient detection of rare circuit failures. The targeted active-learning framework will be supported by the development of machine-learning model foundations and robust learning methods that can scale to high-dimensional parameter spaces. The key objective of this project is to make extremely-rare failure discovery and identification of the underlying failure mechanisms practically viable by extracting the maximum amount of useful information possible from a small amount of available data. The proposed extremely-rare failure discovery work will be broadly applicable to verification and failure analysis of analog, mixed-signal, radio-frequency, and memory circuits with stringent failure specifications and many other types of mission-critical systems.

This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Collaborative Research: SHF: Medium: Data-Efficient Uncovering of Rare Design Failures for Reliability-Critical Circuits

Biological neural networks process streams of temporal information at efficiencies and proficiencies well exceeding those of man-made systems. Recent work in understanding brain dynamics from the point of view of machine learning is starting to demystify the mechanisms behind their extraordinary performance. By distilling these mechanisms in neuromorphic technologies, the prospect of practical brain-like processing at the edge is becoming real. However, the tools at the disposal of neuroscientists and engineers to prototype and train such models are still inadequate. In this poster, I explain the potential rewards and challenges of training biological neural networks, namely Spiking Neural Networks (SNNs). I will provide the roadmap for the solutions to these problems, which build on an exciting combination of autodifferentiation techniques and dynamics inspired by neurobiology.
