09:00 – 10:20 – SBMicro Tutorial – Augmenting silicon technologies with graphene
Francesca Iacopi (University of Technology Sidney, Australia)
Location: SBMicro Cadence Auditorium
Chair: Michelly de Souza (FEI, Brazil)
ABSTRACT: Harnessing graphene’s properties on a silicon platform could augment integrated technologies with a broad range of novel miniaturized functionalities. We will review the learnings from the development of our epitaxial graphene on silicon carbide on silicon technology and some of its most promising applications. This platform allows to obtain any complex graphene -coated silicon carbide 3D nanostructures in a site – selective fashion at the wafer -scale and with sufficient adhesion for integration. Key capabilities for nano-optics and metasurfaces in the MIR are specifically unlocked by the graphene/silicon carbide combination. We have recently demonstrated that the sheet resistance of epitaxial graphene on 3C-SiC on silicon is comparable to that of epitaxial graphene on SiC wafers, despite substantially smaller grains. We also indicate that the control of the graphene interfaces, particularly when integrated, can be a more important factor than achieving large grain sizes. In addition, we show that well- engineered defects in graphene are preferable to defect -free graphene for most electrochemical applications, including biosensing. Promising examples of application of this technology in the More than Moore domain include integrated energy storage, MIR sensing and detection, and sensors for electro-encephalography.

Location: SBCCI Synopsys Auditorium
Chair: Arthur Lorenzon (UFRGS, Brazil)
ABSTRACT: Digital image/video coding has been widely used in our daily life products. Nowadays, nearly every video-enabled device has image/video coding modules. In the past 30 years, several series of international image/video coding standards have been developed and adopted by industry. Recently, learning-based image/video coding, particularly end-to-end learned image/video coding, shows great promise in many emerging applications, e.g. perceptual compression for realism and application-specific image/video compression. This fast growing sector has attracted more than 100+ publications in the literature, with the state-of-the-art end-to-end learned image coding showing comparable compression performance to H.266/VVC intra coding in terms of PSNR and much better MS-SSIM results. End-to-end learned video coding is also catching up quickly. Some preliminary studies report comparable PSNR results to H.265/HEVC or even H.266/VVC under the low-delay setting. These interesting results have led to intense activity in international standards organizations (e.g. JPEG AI) and various Challenges (e.g. CLIC at CVPR and Grand Challenge on Neural Network-based Video Coding at ISCAS). This talk shall give an overview of this field, introducing some notable systems and recent breakthroughs. Furthermore, it shall disclose research opportunities related to the hidden aspects of this new technology.

10:40 – 12:00 – SBCCI Tutorial – Electronic system-level design for hardware IP protection
Christian Pilato (POLIMI, Italy)
Location: SBCCI Synopsys Auditorium
Chair: Gabriel Nazar (UFRGS, Brazil)
ABSTRACT: The globalization of the electronics supply chain allows for the reduction of chip manufacturing costs but poses new security threats. Untrusted foundries can steal the intellectual property in the chips, while malicious users can tamper with the systems to harm their execution, steal sensitive information, or support reverse engineering. The design of next-generation systems demands the introduction of such security concepts at higher levels of abstraction. In this tutorial, I will present an overview of the security concerns in the design of heterogeneous system-on-chip architectures. I will also discuss how traditional methods for electronic system-level design can be extended to design and prototype architectures with secure communications, to automatically synthesize security countermeasures, and to protect existing IP hardware modules.

13:40 – 15:00 – SBCCI Tutorial – Reliable In-memory Computing with Unreliable Devices and Circuits
Kevin Yu Cao (Arizona State University, USA)
Location: SBCCI Synopsys Auditorium
Chair: José Augusto Nacif (UFV, Brazil)
ABSTRACT: With the ever-increasing demand of AI algorithms and high-definition sensors, Contemporary microprocessor design is facing tremendous challenges in memory bandwidth, processing speed and power consumption. Leveraging the advances in device technology and design techniques, in-memory computing (IMC) embeds analog deep-learning operations in the memory array, achieving massively parallel computing with high storage density. On the other side, its performance is still limited by device non-idealities, circuit precision, on-chip interconnection, and algorithm properties. In this talk, we will first review the state-of-the-art IMC design techniques, such as those based on resistive random-access memory (RRAM) and SRAM. Then based on statistical data from a fully integrated 65nm CMOS/RRAM test chip, we will illustrate the bottlenecks of current IMC system, including RRAM variations, the stability of machine learning models, peripheral circuits and interconnection. They interact with each other, limiting the inference accuracy and system energy-delay product (EDP). To efficiently explore design space, we will present a newly developed benchmark simulator, SIAM, which integrates device, circuit, architecture, network-on-chip (NoC), network-on-package (NoP) and DRAM access models to address the bottlenecks in data movement and robustness. Furthermore, we will demonstrate two methods to recover the accuracy loss: training for model stability before mapping to the hardware, and a hybrid SRAM/RRAM architecture for post-mapping recovery. These methods are applied to various datasets as well as a 65nm SRAM/RRAM test chip, helping shed light on future IMC research focus.

15:20 – 16:40 – SBMicro Tutorial – Reliability of Metal Gate / High-K CMOS devices
Andreas Kerber (INTEL, USA)
Location: SBMicro Cadence Auditorium
Chair: Rodrigo Trevisoli Doria (FEI, Brazil)
ABSTRACT: Aggressively scaled transistor technologies with metal gate/high-k stacks encounter additional reliability challenges beside bias temperature instability (BTI) in PMOS and NMOS devices, time dependent dielectric breakdown and hot carrier degradation. Time-zero variability and variability induced by device aging is a growing concern which needs to be modeled using stochastic processes. The physical nature of the stochastic process remains under debate and to support model development efforts large statistical data sets are essential. In addition, self-heating during reliability testing can be observed in novel device structures like bulk FinFET, SOI FinFETs, FDSOI and gate-all-around devices and needs proper attention. Furthermore, to increase the confidence in the discrete device reliability models, device-to-circuit correlations need to be established. In this presentation we discuss how to obtain stochastic BTI data for discrete SRAM and logic device beyond 3sigma, address device-to-circuit correlations using ring-oscillators and explore self-heating effects in FinFET and SOI devices.

15:20 – 16:40 – SBCCI Tutorial – Interconnect Meets Architecture: On-Chip Communication in the Age of Heterogeneity
Partha Pratim Pande (Washington State University, USA)
Location: SBCCI Synopsys Auditorium
Chair: Mateus Rutzig (UFSM, Brazil)
ABSTRACT: Neural Networks, graph analytics, and other big-data applications have become vastly important for many domains. This has led to a search for proper computing systems that can efficiently utilize the tremendous amount of data parallelism that is associated with these applications. Generally, we depend on data centers and high-performance computing (HPC) clusters to run various big-data applications. However, the design of data centers is dominated by power, thermal, and physical constraints. On the contrary, emerging heterogeneous manycore processing platforms that consist of CPU and GPU cores along with memory controllers (MCs) and accelerators have small footprints. Moreover, they offer power and area-efficient tradeoffs for running big-data applications. Consequently, heterogeneous manycore computing platforms represent a powerful alternative to the data center-oriented type of computing. However, typical Network-On-Chip (NoC) infrastructures employed on conventional manycore platforms are highly sub-optimal to handle specific needs CPUs, GPUs, and accelerators. To address this challenge, we need to come up with a holistic approach to design an optimal network-on-chip (NoC) as the interconnection backbone for the heterogeneous manycore platforms that can handle CPU, GPU, and application-specific accelerator communication requirements efficiently. We will discuss design of a hybrid NoC architecture suitable for heterogeneous manycore platforms. We will also highlight effectiveness of machine learning-inspired multi-objective optimization (MOO) algorithms to quickly find a NoC that satisfies both CPU and GPU communication requirements. Widely used MOO techniques (e.g., NSGA-II or simulated annealing based AMOSA) can require significant amounts of time due to their exploratory nature. Therefore, more efficient, and scalable ML-based optimization techniques are required. We are going to discuss various features of a generalized application-agnostic heterogeneous NoC design that achieves similar levels of performance (latency, throughput, energy, and temperature) as application-specific designs. In this talk, we will first review the state-of-the-art IMC design techniques, such as those based on resistive random-access memory (RRAM) and SRAM. Then based on statistical data from a fully integrated 65nm CMOS/RRAM test chip, we will illustrate the bottlenecks of current IMC system, including RRAM variations, the stability of machine learning models, peripheral circuits and interconnection. They interact with each other, limiting the inference accuracy and system energy-delay product (EDP). To efficiently explore design space, we will present a newly developed benchmark simulator, SIAM, which integrates device, circuit, architecture, network-on-chip (NoC), network-on-package (NoP) and DRAM access models to address the bottlenecks in data movement and robustness. Furthermore, we will demonstrate two methods to recover the accuracy loss: training for model stability before mapping to the hardware, and a hybrid SRAM/RRAM architecture for post-mapping recovery.

11:00 – 12:20 – KEYNOTE – Reliability of VLSI technologies: impediment and opportunity
Ben Kaczer (IMEC, Belgium)
Location: SBMicro Cadence Auditorium
Chair: Gilson Wirth (UFRGS, Brazil)
ABSTRACT: Presence of non-idealities and defects in VLSI technologies is an immutable reality, which, however, is often overlooked by device engineers, researchers, technologists, and designers alike. We argue that in fact VLSI reliability “makes or breaks” any new technology. Superficial device reliability optimization is possible using phenomenological observations only, but we argue that solid physical foundations and thorough understanding of the underlying degradation mechanisms are essential both for truly dependable lifetime projections and for novel device pathfinding. Based on the detailed investigation of gate oxide defects, our “defect engineering” approach enables, among other things, optimization paths for SiGe channel devices and new oxidation techniques for advanced gate-all-around architectures, such as nanosheets and forksheets. In deeply scaled devices, degradation mechanisms can be decomposed down to individual defects, with each defect measured separately and its properties described down to single Kelvin temperatures using quantum mechanics. Such knowledge then allows us e.g. to model the degradation statistics of deeply-scaled devices and to predict the likelihoods of their failure. Robust degradation models enable us to project wider safe operating areas, which in turn allow to design better-performing circuitry at a given technology node and thus limited costs. Moreover, the ubiquitous presence of defects can be in fact embraced and the in-depth knowledge of defect properties can be used to our advantage to design new devices and applications, ranging from memory to physically unclonable functions and tamper-aware aging monitors.

11:00 – 12:20 – KEYNOTE – Towards Next Generation Logic Synthesis and Verification
Alan Mishchenko (University of California, Berkeley, USA)
Location: SBMicro Cadence Auditorium
Chair: André Reis (UFRGS, Brazil)
ABSTRACT: Given the progress achieved over the last fifty years in logic synthesis and verification, it is tempting to believe that most of the research discoveries have already been made, and the role of future researchers and engineers is just to maintain the CAD tools and occasionally make small changes, such as adding concurrency or employing machine learning to generate better scripts. Nothing could be farther from the truth. In this talk, we explore several orthogonal innovations in the fundamental research used to build synthesis tools targeting FPGAs and ASICs. These innovations include using novel data structures, leveraging synergistic optimization engines, and simultaneously exploring previously-unrelated search spaces. Most of these improvements are work-in-progress with early results demonstrating better quality and faster runtimes.

09:00 – 09:40 – SBMicro Invited Talk – MOSFET Threshold Voltage Extraction Methods
Adelmo Ortiz-Conde (Universidad Simon Bolivar, Venezuela)
Location: SBMicro Cadence Auditorium
ABSTRACT: In the early days of MOSFETs’ development, the threshold voltage was a very important parameter for circuit simulation because the SPICE models were based on threshold voltage. Nowadays, the most sophisticated SPICE models are based on surface potentials and not on threshold voltage. Nevertheless, the threshold voltage is still the most important electrical parameter in modeling MOSFETs because of reliability issues. We review and scrutinize the several different threshold voltage extraction methods.

14:00 – 14:40 – SBCCI Invited Talk – Hardware/Software Co-Design of Deep Learning Accelerators
Yiyu Shi (University of Notre Dame, USA)
Location: SBCCI Synopsys Auditorium
Chair: José Augusto Nacif (UFV, Brazil)
ABSTRACT: The prevalence of deep neural networks today is supported by a variety of powerful hardware platforms including GPUs, FPGAs, and ASICs. A fundamental question lies in almost every implementation of deep neural networks: given a specific task, what is the optimal neural architecture and the tailor-made hardware in terms of accuracy and efficiency? Earlier approaches attempted to address this question through hardware-aware neural architecture search (NAS), where features of a fixed hardware design are taken into consideration when designing neural architectures. However, we believe that the best practice is through the simultaneous design of the neural architecture and the hardware to identify the best pairs that maximize both test accuracy and hardware efficiency. In this talk, we will present novel co-exploration frameworks for neural architecture and various hardware platforms including FPGA, NoC, ASIC and Computing-in-Memory, all of which are the first in the literature. We will demonstrate that our co-exploration concept greatly opens up the design freedom and pushes forward the Pareto frontier between hardware efficiency and test accuracy for better design tradeoffs.

14:00 – 14:40 – SBMicro Invited Talk – Field Effect Transistors: From MOSFET to Tunnel FET and Beyond
João Martino (Escola Politécnica da USP, Brazil)
Location: SBMicro Cadence Auditorium
ABSTRACT: The Field Effect Transistor (FET) is the main device for the integrated circuits era. This presentation starts with an overview of the main progress steps of FET evolution (Figure 1) and finish with a discussion of possible FET devices for future technologies. The starting point was the Lilienfeld patent filled in 1925 [1] that was not fabricated due to the technological difficulties. Experimental Metal-Oxide-Semiconductor FET (MOSFET) was only obtained in 1960 [2]. The classical MOSFET was composed by Aluminum (Metal), silicon dioxide (Oxide) and Silicon (Semiconductor). In order to follow the Moore´s Law [3] evolution and to avoid the short channel effects the classical MOSFET have to be upgraded using new materials and new device structures in order to improve the electrostatic control between gate and channel. The MOSFET has been upgraded with different gate electrode like polysilicon heavily doped, TiN and TaN. The gate oxide has also been replaced to high-k dielectrics like SiON, HfSiON and HfO2 in order to avoid gate leakage current. Finally, the well-known silicon channel has also been modified to strained silicon, SiGe, Ge, InGaAs in order to boost the carriers mobility. The MOSFET structure has been improved from Bulk MOSFET to SOI (Silicon-on-Insulator) [4] MOSFET and later from planar to vertical multiple-gate devices like FinFET [5], Triple Gate and Gate all around devices like nanowire [6] and nanosheets [7] for enhancing the gate to channel electrostatic coupling. New type of device conduction mechanism like Tunnel-FET [8] devices (TFETs) have been studied to replace the conventional drift-diffusion conduction mechanisms due to the benefits obtained by tunneling conduction. The analog behavior of the TFET [9] device and some basics circuits like operational transconductance amplifier designed with TFETs [10-12] will be discussed and compared with conventional tecnologies. Finally, reconfigurable transistors will also be discussed [13].

ABSTRACT: Synaptic devices are recognized as the essential component of brain-inspired neuromorphic hardware, which have attracted extensive attention in emerging neuron circuits and artificial intelligence. By means of biocompatibility, low-cost, and a simple fabrication process, organic thin-film synaptic devices may offer a strategy for building blocks of organic neuromorphic circuits. This presentation will briefly introduce the device design, device behaviors and working mechanism of several types of organic synaptic devices, such as organic thin-film memristors and organic thin-film memtransistors. The synaptic plasticity, including both short-term and long-term plasticity, has been successfully emulated with our devices. The robust device performance makes it a potential candidate for hardware implementation of future neural network.

14:00 – 14:40 – SBMicro Invited Talk – Performance of Silicon-On-Insulator Nanowire and Nanosheet MOSFETs In a Wide Temperature Range
Marcelo Pavanello (Centro Universitario FEI, Brazil)
Location: SBMicro Cadence Auditorium
ABSTRACT: The aggressive scaling of MOSFET dimensions triggered the search for alternative solutions to the traditional planar transistors for future technological nodes, due to the occurrence of undesirable short-channel effects (SCE). Nanowire and nanosheet MOSFETs are considered excellent enablers for the continuation of MOSFET scaling into the nanometer regime [1], replacing the FinFETs. These structures provide excellent electrostatic control of the channel, appreciably reducing the occurrence of SCE. Triple-gate Ω-shaped MOSFETs with both HFIN and WFIN of similar dimensions, in the order of 10 nm, referred to as nanowires (NWs) in the literature, are promising contenders. Due to their tridimensional architecture, NWs have demonstrated great scalability with both Si [1] and SiGe material [2]. Additionally, the small cross-section of nanowires enabled the fabrication of devices without PN junctions, so-called junctionless transistors [3]. Nanowires demonstrated excellent electrical properties for both digital and analog applications [4,5]. Also, recently, the ability to stack 2 or more levels of nanowires and/or nanosheets and make them operate as a single transistor improved the MOSFET current per footprint while retaining the excellent SCE immunity of single-level nanowires [6].
This work will present the performance of single-level, stacked nanowires and nanosheets fabricated in Silicon-On-Insulator (SOI) substrates. Analytical models for describing the electrical characteristics of these devices will be presented [7,8]. Also, the performance of these devices operating in a wide range of temperatures, from 600 K down to the cryogenic range [9,10,11], looking for their integration in future quantum computing applications, will be presented and discussed. Peculiarities of these devices operating in extreme temperatures, such as quantum transport in narrow nanowires at cryogenic temperatures and degraded Gate-Induced Drain Leakage at high temperatures will be presented and discussed.

Jari Nurmi (Tampere University, Finland)
Location: SBCCI Synopsys Auditorium
Chair: Luciano Ost (Loughborough University, UK)
ABSTRACT: The concept of Reconfigurable Computing (RC) was proposed already in 1960s. Coarse-Grained Reconfigurable Arrays (CGRA) as a realistic implementation architecture for RC have been around for a couple decades already, but there has not been any big breakthrough in the adoption of CGRA. Although they have many desirable and appealing features, some challenges remain. In this presentation we will look at various CGRA architectures and try to assess their opportunities in solving today’s computing problems, especially trying to find matches to another emerging paradigm, Approximate Computing (AC). The challenges and weaknesses of CGRAs, and attempts to circumvent them, will also be pointed out.

14:00 – 14:40 – SBMicro Invited Talk – Innovation by ASIC design, Training and Related Issues
Jacobus Swart (FEEC-UNICAMP, Brazil)
Location: SBMicro Cadence Auditorium
ABSTRACT: Innovation has been increasingly intense in many fields and often with the use of ASIC. Smart cities, IoT, Industry 4.0, wearables, medicine, security, artificial intelligence, VR/AR, are some examples that require new and specific components, forming segmented and differentiated markets. This scenario gives opportunity and need for many new products, requiring new projects and many CI designers.
IC prototyping using the multi-project wafer (MPW) model has been a common practice for teaching, research and development and followed by engineering and/or small production, before reaching full production.
The successful ASIC design is based on many issues related to microelectronics knowledge. A good designer needs to have good skills in these subjects, have gone through intense training in EDA tools and practical training through actual tape-out, fabrication and testing.
The MPW model started in the 1970s and has been successfully used in electronic IC prototyping, and today it is also applied in MEMS and IC prototyping and photonics, being offered through EUROPRACTICE and other organizations.
The APCI program provides EDA licenses to universities in the country, in addition to funding ASIC prototyping by international MPW service, thus contributing to development and innovation in the country.
