        Neurons in the brain interact with each other through electrical and chemical signals. These interactions determine how the brain detects and processes information. Simultaneous detection of the activity of many neurons is crucial for understanding the brain function. I will describe electrical and optical methods of interacting with neural networks developed with SCIPP’s participation. I will also discuss some of the neuroscience findings obtained obtained with the developed methods.

        LCLS-II: A High Repetition Rate X-Ray Laser Facility 45m

        The Linac Coherent Light Source (LCLS) is in the midst of a major upgrade called LCLS-II [1]. This upgrade will add a 4 GeV continuous-wave superconducting electron accelerator to the LCLS complex, delivering a 10,000-fold increase in repetition rate and average x-ray brightness. Currently scheduled to achieve first light in 2020, LCLS-II will enable a broad range of experiments over a 0.2 to 5 keV photon energy range presently not possible to date [2]. These experiments will be conducted in three newly developed x-ray instruments. The scope, projected capabilities and status of the LCLS-II project and associated x-ray instruments will be presented as well as exemplary science applications.

        Radiation Hardness Studies and Evaluation on SRAM-Based FPGA for High Energy Physics Experiments 25m

        Being a proposed solution for the digital boards of the upgraded LHCb RICH sub-detectors, SRAM-based FPGA devices have become widely used in high energy physics experiments. These studies aim to present the radiation hardness measurements done on the KINTEX-7 FPGA during irradiation with protons, X-rays and ions beams. For multiple values of the total ionising dose, linear energy transfer and proton energy, the cross sections of single-event-effects are estimated. We also give separate results for specific resources type: configuration RAM, block RAM, I/O banks and logic. Conclusions are reached on the radiation tolerance of this chip family in LHC environment.

        Effect of Gamma Irradiation on Leakage Current in CMOS Readout Chips for the ATLAS Upgrade Silicon Strip Tracker at the HL-LHC 25m

        As part of the program for the upgrade of the ATLAS inner tracker for the High Luminosity LHC, irradiations have been carried out with 60Co gamma source. The measurements characterize the increase in the leakage current in the 130 nm-technology readout chips. The current as a function of total ionizing dose has been studied under different conditions: dose rate, temperature, power applied to the chip and pre-irradiation. The results show unique features that provide valuable information for the understanding of the mechanisms responsible for radiation damage in transistors. Models that attempt to parameterize the leakage current will also be presented.

        A SEU Tolerant Latches Study for the RD53A Chip 25m

        Abstract:
        The RD53 collaboration was established to develop the next generation of pixel readout chips needed by ATLAS and CMS at the HL-LHC and requiring extreme rate and radiation tolerance. The 65 nm CMOS process is adopted in order to satisfy the high level of integration requirement. The SEU immunity for this highly scaled process should be carefully considered because the device dimensions are small and the capacitance of the storage nodes becomes very low.
        A chip prototype including different SEU tolerant structures was designed in the TSMC 65nm technology and proton irradiation tests were done in order to estimate the SEU tolerance of the proposed structures.

        An FPGA-Based Track Finder for the L1 Trigger of the CMS Experiment at HL-LHC 25m

        A new tracking detector is under development for use by the CMS experiment at the High-Luminosity LHC. This upgrade will allow to reconstruct within a few microseconds charged particle tracks with transverse momentum above 3 GeV, for use in the Level-1 trigger. A concept for an FPGA-based track finder using a fully time-multiplexed architecture is presented, reconstructing tracks using an Hough Transform based algorithm. A hardware demonstrator using MP7 boards has been assembled. It operates on 1/8 of tracker solid angle at a time, processing events taken at 40 MHz with up to 200 superimposed proton-proton interactions, satisfying latency constraints.

        The Muon-to-Central Trigger Processor Interface (MUCTPI) of the ATLAS experiment at CERN will be upgraded for run 3 of the LHC. The current system, a full 9U VME crate, will be replaced by a single AdvancedTCA blade, based on state-of-the-art FPGA technology and high-density ribbon fibre-optic transmitters and receivers. The module uses a System-on-Chip (SoC) with a processor running an embedded Linux operating system to communicate with the experiment run control system. We present the hardware design and implementation of the module, the communication model used in the SoC as well as results from the validation of the first prototype.

        Development of the jet Feature EXtractor (jFEX) for the ATLAS Level 1 Calorimeter Trigger upgrade at the LHC 25m

        To cope with the enhanced luminosity delivered by the Large Hadron Collider in 2021, the ATLAS experiment has planned a major upgrade. The first level trigger based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature Extractors (FEXs), each optimized to trigger on different physics objects. This presentation is focused on the jet FEX.
        The main challenges of such a board are the input bandwidth of up to 3 Tb/s, dense routing of high-speed signals and power consumption. We report on design, firmware development and results of integrated tests of a prototype.

        CBC3: a CMS Micro-Strip Readout ASIC with Logic for Track-Trigger Modules at HL-LHC 25m

        The CBC3 is the latest version of the CMS Binary Chip for readout of the outer radial region of the upgraded CMS Tracker at HL-LHC. This 254-channel, 130nm CMOS ASIC is designed to be bump-bonded to a substrate to which sensors will be wire-bonded. It will instrument double-layer 2S-modules, consisting of two overlaid silicon micro-strip sensors with aligned micro-strips. On-chip logic identifies L1 trigger primitives from high transverse-momentum tracks by selecting correlated hits in the sensors. Delivered in late 2016, the CBC3 has been under test for several months, including x-ray irradiations and SEU testing. Results and performance are reported.

        This works presents the design and experimental study of a radiation hardened Phase Locked Loop (PLL) for high speed serial-communication links. These research results are used for the LpGBT (Low Power Gigabit Transceiver) chip which will be widely used for optical data-links between the detectors and the counting rooms in the HL–LHC experiments. The PLL features a novel LC-oscillator architecture which is 600× less sensitive than traditional structures. Additionally, the circuit uses triple-modular redundancy and is designed in 65nm CMOS. The paper will present experimental results on X-ray Total Ionizing Dose (TID), heavy ion SEU and two-photon absorption laser tests.

        An 8-Channel ASD in 130 nm CMOS with Superior Performance of Rise Time, Noise and Threshold Uniformity for ATLAS Drift Tube Readout at the HL-LHC 25m

        ATLAS Muon-Drift-Tubes spatial resolution-&-efficiency depend on drift-time resolution, noise levels, and accurate threshold setting. A new 130nm read-out device is developed and optimized, for the required time resolution, to guarantee rise-times below 10ns, with acceptable time-slewing effects. Moreover, the large chain-amplification results in increased sensitivity to any disturbance (mainly from supply). To avoid additional costs to clean up the set-up from such disturbs, the read-out chain adopts innovative techniques (at system, circuit, and design levels) minimizing read-out chain disturb sensitivity. This paper details the design strategy, compares post-layout simulation with measurements and presents resolution studies in CERN high-energy testbeam.

        Quality Control Considerations for the Development of the Front End Hybrid Circuits for the CMS Outer Tracker Upgrade 25m

        The upgrade of the CMS Outer Tracker for the HL-LHC requires the design of new double-sensor modules. They contain two high-density front end hybrid circuits, equipped with flip-chip ASICs, passives and mechanical structures. First prototype hybrids in a close-to-final form have been received from three manufacturers. To qualify these hybrids a test setup was built, which emulates future tracker temperature and humidity conditions, provides temporary interconnection, and implements testing features. The system was automated to minimize the testing time in view for the production phase. Failure modes, deliberately implemented in the produced hybrids, provided feedback on the system’s effectiveness.

        A microTCA based readout system was developed to test multiple front-end hybrids simultaneously. Therefore the concurrent information of the full module can be used for differential and common-mode noise characterization, as well as for signal tests with radioactive sources or cosmic particles.

        SEE Tolerant Standard Cell Based Design While Guaranteeing Specific Distance Between Memory Elements 20m

        Single Event Effects (SEEs) comprising of Single Event Upsets (SEUs) and Single Event Transients (SETs) corrupts the data in storage nodes/registers. Triple Modular redundancy (TMR) with clock delay insertion is a system level technique that counters SEEs in storage nodes. However, such an implementation is not straight forward in standard cell based digital design which uses cad tools like Genus/RC compiler and Innovus for synthesis & Physical design. This paper presents a successful automation methodology that maps the intended registers in the Verilog RTL with triplicated cell during synthesis and guarantees minimum distance between memory elements during placement & routing leading to SEE tolerant standard cell based digital design.

        Clock and Trigger Distribution for ALICE Using the CRU FPGA Card 20m

        ALICE is preparing a major upgrade for 2021.

        Subdetectors upgrading their counting room DAQ electronics will use a
        common hardware to receive physics data: the Common Readout Unit (CRU).
        The same CRU will also distribute the LHC clock and trigger to many of
        the upgrading subdetectors (~7800 front end cards).

        Requirements are strict: for the clock the allowed jitter (RMS) is
        typically <300ps, and <30ps for timing critical subdetectors; the
        allowed skew is typically <1ns, and <100ps for timing critical
        subdetectors. A constant latency for distributing the trigger is a
        must.

        Techniques used to meet these requirements will be presented.

A Microsemi Igloo2 FPGA acts as the VME master and interfaces the GBTx link for transmitting data and receiving triggers and a low- jitter clock. Compared to the old board, the DRM2 is able to cope with faster trigger rates and provides a larger data bandwidth towards the DAQ. The measurements on the received clock jitter and data transmission performances in a full crate are given.

        The High-Luminosity LHC (HL-LHC) is planned to start the operation in 2026 with an instantaneous luminosity of 7.5 x 1034 cm-2s-1. To cope with the event rate higher than that of LHC, the trigger and readout electronics of ATLAS Thin Gap Chamber will be replaced and an advanced muon trigger with fast tracking will be implemented. A frontend board prototype was developed and the functions for HL-LHC including the data transfer of 256 channels with a 16 Gbps bandwidth have been demonstrated.

The sensor features a $45\times216$ pixel array with a 40$\mu$m pixel pitch which collects and measures external charge directly through exposed metal electrodes in the topmost metal layer. Each pixel contains a low-noise charge-sensitive preamplifier to establish the analog signal, which is accessible through a time-shared multiplexer. Initial tests show that the sensor achieved a $<10{e^-}$ analog noise per pixel. These characteristics enable its use as the charge readout device in future Time Projection Chambers without gas-avalnche gain, which has unique advantages in low background and low rate-density experiments.

        The increase of luminosity foreseen for the Phase-II HL-LHC upgrades calls for new solutions to fight against the expected pile-up effects. One approach is to measure very accurately the time of arrival of the particles with a resolution of few tens of picoseconds. In addition, a spatial granularity better than a few millimeter will be needed to obtain a fake jet rejection rate acceptable for physics analyses. These goals could be achieved by using the intrinsic benefits of a standard High-Voltage CMOS technology -in conjunction with a high-resistivity detector material- leading to a fast, integrated, rad-hard pixel sensor ASIC.

The consistence between the ASIC design simulation and measurements validates the ASIC characterization.

        Time-to-Digital Converter with Adjustable Resolution Using a Digital Vernier Ring Oscillator 15m

        This paper reports the development of a high resolution, low power, and adjustable in frequency Time-to-Digital Converter (TDC), based on two vernier Ring Oscillators (RO) made of standard XOR cells. The TDC is aimed at exploiting the excellent timing performance of the multigap Resistive Plate Chambers (RPC). The frequency of each RO is adjustable thanks to a 9-bit register from 340MHz to 370MHz, allowing theoretically an LSB selection down to one picosecond. The core area measures 35 $\times$75 $\mu m^{2}$ in a 130nm CMOS technology. Under 1.2V, the TDC consumes 2.3 m$A_{RMS}$ and 260 n$A_{RMS}$ with or whithout signal respectively.

        Two High-Speed Dual-Channel VCSEL Driver 15m

        We present two designs of a dual-channel VCSEL driver ASIC, named LOCld130 and LOCld65, aiming for the upgrade of ATLAS Liquid Argon Calorimeter. Each channel of the driver operates at 5 Gbps or 10 Gbps respectively. They are implemented in commercial 130 nm and 65 nm CMOS technologies. In typical case the 5 Gbps driver dissipates 56 mW/channel (VCSEL included) and the 10 Gbps 58 mW/channel. Both designs will be prototyped this summer.

The development of a new control board, called the 3CU for the electromagnetic and hadronic calorimeters was proposed. This board receives commands from the main LHCb control system and sends them through the backplane to the front-end boards. Each calorimeter crate is equipped with one unique 3CU plugged in the central slot which also provides the clock, slow controls, and Fast Control command to all the boards inside the same crate.

        The digitization stage of the main electromagnetic calorimeter of the CBELSA/TAPS experiment in Bonn (Germany) is being equipped with custom 80 MSPS, 14 bit Sampling-ADCs. Onboard data processing with FPGAs allows determination of the signal characteristics, reducing the data substantially. The readout of the unprocessed sampling data allows offline analysis and refinement of the FPGA-algorithms.

        A partial setup has shown promising results during a photoproduction-beamtime. It has been demonstrated that the SADCs are able to overcome the readout-rate limitation of the current QDC readout.

        Low Voltage Powering of On-Detector Electronics for HL-LHC Experiments Upgrades 15m

        All LHC experiments will be upgraded during the next LHC long shutdowns (LS2 and LS3). The use of more advanced CMOS technology nodes typically implies higher current consumption of the on-detector electronics. In this context, and in view of limiting the cable voltage drop, point-of-load DC-DC converters will be used on detector. This will have a direct impact on the existing powering scheme, implying new AC-DC and/or DC-DC stages as well as changes in the power cabling infrastructure. This paper will present the first results obtained while evaluating different LV powering schemes and distribution layouts for HL-LHC trackers.

        Electro-Migration Driven Failures on Miniature Silver Fuses at the Large Hadron Collider 15m

        In the Large Hadron Collider (LHC), the cryogenics instrumentation infrastructure uses fuse-protected high-voltage isolated temperature transducer cards. Spurious faults were observed at their miniature silver fuses during the periods 2008-2010 and 2014-2016 and a study was launched to understand the underlying failure mechanism.

        The study uses data from Scanning Electron Microscopy (SEM), spectrometry, Weibull reliability calculations, operating temperature profiles and existing data logging tools. For the period 2014-2016, the fuse failures followed a Weibull distribution of β = 3.91 and η = 2323 days. The leading failure mechanism was attributed to electro-migration phenomena.

        Modern data acquisition techniques employed in particle physics create large amounts of digital data that must be transmitted to remote electronics and computers for further processing. Increasingly, bandwidth requirements preclude the use of PCB traces and traditional copper cabling, even for modest interconnection length. Fortunately, novel copper and optical flyover solutions are being developed to go around the limits of traditional PCB and cabling, enabling transport of data at rates exceeding 28 Gb/s per lane over a range of distances. We will describe advances in miniature, very high speed connectors, micro-coax and micro-twinax cabling, and on board optical transceivers that can meet present and future interconnect challenges.

        FED Firmware Interface Testing with Pixel Phase 1 Emulator 15m

        A hardware emulation of the CMS pixel detector phase 1 upgrade front-end electronics was developed to test and validate the architecture of front-end driver (FED) firmware. The emulation, implemented on the CERN GLIB uTCA platform, drives optical transmitters to the back-end electronics. The firmware emulates the complex functions of the readout chips and Token Bit Managers and allows for possible exceptions in the output data. The emulation implements fixed data patterns and realistic simulated data to drive readouts at expected data and trigger rates. Testing software was developed to control and verify correct transmission of data and exception handling in the FED.

        A SEU-Immune Self-Tuned Pixel Chip Architecture 15m

        Readout chips of hybrid Pixel detectors use low power amplifier and threshold discrimination to sense and digitise charge deposited in semiconductor sensor. Due to variability in CMOS transistors each pixel circuit needs to be calibrated individually to achieve response uniformity. Traditionally this is addressed by programmable threshold trimming in each pixel. In this presentation a self-adjusting threshold mechanism is presented, which corrects the threshold for both spacial and time variation. The behaviour of this circuit has been simulated to evaluate its performance compared to traditional calibration results. The simulation results show that this mechanism can perform equally well, but eliminates instability over time and is immune to single event upsets.

        Upgrades over the next decades will enable LHC to operate at a higher luminosity (HL-LHC). Accordingly, the optical links designed to transmit collision data should be hardened against increased radiation levels, allowing for a reliable communication. This paper studies fibre cabling design of a generic link between the in-detector optical front-end and the counting room. The proposed solution concatenates radiation-resistant and conventional fibres using multi-fibre interconnections. The radiation penalty calculation considers a temperature of ‒30°C inside the detector innermost part. The maximum link loss during HL-LHC lifetime is estimated to be 3.16dB, complying with predefined margins of Versatile Link system.

        ALICE Trigger System for LHC Run 3 15m

        The ALICE Central Trigger Processor (CTP) is going to be upgraded for LHC Run 3 with completely new hardware and a new Trigger and Timing Control (TTC) system based on a Passive Optical Network (PON) system. The new trigger system has been designed as dead time free and able to transmit trigger data at 9.6 Gbps. A new universal trigger board has been designed, where by changing the FMC card, it can function as a CTP or as a LTU. It is based on the Xilinx Kintex Ultrascale FPGA and upgraded TTC-PON.

        Data Analysis at Level-1 Trigger Level 15m

        With ever-increasing luminosity at the LHC, optimum online data selection is getting more and more important. While in the case of some experiments (LHCb/ALICE) this task is being completely transferred to computer farms, the others - ATLAS/CMS - will not be able to do this in the medium-term future for technological, detector-related reasons. Therefore, these experiments pursue the complementary approach of migrating more of the offline and high-level trigger intelligence into the trigger electronics. The presentation will illustrate how the Level-1 Trigger of the CMS experiment and in particular its concluding stage, the so-called “Global Trigger”, take up this challenge.

        Development of the New Trigger Processor Board for the ATLAS Level-1 Endcap Muon Trigger for Run-3 15m

        The ATLAS first-level Endcap Muon trigger in LHC Run-3 will
        identify muons by combining data from the Thin-Gap chamber detector (TGC) and a new detector, called the New-Small-Wheel (NSW). In order to handle data from both TGC and NSW, new trigger processor board has been developed. The board has a modern FPGA to make use of Multi-Gigabit transceiver technology. The readout system for trigger data has also been implemented with TCP/IP instead of a dedicated ASIC. This presentation will focus on the electronics and its firmware of the ATLAS first-level Endcap Muon trigger processor board for LHC Run-3.

The processor will fit candidate muon tracks in the drift tubes in real time, improving significantly the momentum resolution provided by the dedicated trigger chambers. We present a novel pure-FPGA implementation of a Legendre transform segment finder, an associative-memory alternative implementation, an ARM (Zynq) processor-based track fitter, and compact ATCA blade architecture. The ATCA architecture is designed to allow a modular, staged approach to deployment of the system and exploration of alternative technologies.

        Simulations of Busy Probabilities in the ALPIDE Chip and the Upgraded ALICE ITS Detector 15m

        For the LS2 upgrade of the ITS detector in the ALICE experiment at the LHC,
        a novel pixel detector chip, the ALPIDE chip, has been developed. In the event
        of busy ALPIDE chips in the ITS detector, the readout electronics may need
        to take appropriate action to minimize loss of data. A lightweight, statistical
        simulation model for the ALPIDE/ITS has been designed using the SystemC
        framework.

        With the simulations we have been able to quantify the probability of busy
        situations under various conditions, which is crucial knowledge for the further
        design and development of the readout electronics.

        Software Defined Radio Based Readout of Microwave SQUID Multiplexed MMC Arrays 25m

        Metallic magnetic calorimeters (MMC) are new cryogenic detectors that offer a high resolution of single eV, a signal rise time of below 100 ns, a dynamic spectrum of several 10 keV and an almost optimal linearity. MMCs are of high interest for many experiments, such as dark matter detection or neutrino mass specification. Since pixel arrays of the sensor are read out at GHz-Frequency and each single pixel offers a fast rise time, a complex analog and digital readout system is required. This contribution will give an introduction to MMC technology in combination with the implemented readout electronics.

        CMOS Biochips: The Good, the Bad, and the Hype 45m

        In the past two decades, there has been numerous attempts to take advantage of semiconductor solutions, broadly defined, to create high-performance biosensors and bio-molecular detection devices. The goal has always been to create molecular diagnostics technologies that offer the cost efficiency, miniaturization capabilities, and manufacturing robustness of consumer electronics devices. The outcome so far, has not been very exhilarating and unfortunately there has been few impactful products based on such efforts.

        In this talk, we will discuss the use of CMOS processes and IC’s for biotechnology in the form of integrated biochips. The focus will be not only the design, manufacturing, and the packaging tradeoffs of biochips, but also on the applications requirements and ideal use models in molecular biology. We will also discuss, in detail, the recently implemented CMOS biochips for nucleic acid (DNA/RNA) testing applications.

        Abstract

        Continuous advancement in process technology following Moore’s law over the past few decades has greatly increased IC design complexity, not just for designers but also for EDA tools. The drive to reduce feature size beyond optical resolution of visible and ultra-violet light has led to multiple masks/ patterns for same layer to allow for a more compact layout. Need for greater scaling and manufacturing accuracy has led to a self-aligned fabrication process requiring gridded, unidirectional interconnects. At the same time, new devices such as tri-gate finFETS have been introduced to address power, leakage and variability associated with these processes. In addition to more restrictive and complex design rules for manufacturability and process characteristics, EDA tools need to account for changes in design methodology such as highly gridded placement and routing. This presentation will cover these tool enhancements and changes to meet the process technology requirements of these nodes, for both devices and interconnects, with focus on physical implementation.

        Designing CMOS Chips Beyond 65 nm 1h 30m

        Moore's Law has entered a new frontier as device scaling continues to excel in 10nm and beyond. As the physical dimension of devices and interconnect are being shrunk, the design rules and the design flow, for both design community and EDA community, face unprecedented complexity. Conventional design optimization techniques also need to take the novel process technologies, such as multi-gate devices (e.g., FinFET), spacer technology, and self-aligned multiple patterning lithography, into account to achieve the best possible performance, power, and area for a design with more and more functionalities integrated into one single chip.

        In this presentation, first, we will talk about simulation technologies to handle special effects introduced by advanced process nodes, such as high transistor speed, high transistors/RC capacities and reliability effects etc. with reasonable speed and performance while maintaining spice simulation accuracy. Secondly, we will also discuss about advanced integrated simulation environment targeting for different design phases to meet the tight design window. Finally, we will touch upon the importance of system integration for advance process nodes and bring up the solution for the system integration, which include IC/Package/PCB, from both implementation and analysis point of views.
