13:15 Xilinx

XILINX, leading provider of all-programmable logic devices, pursues its strategy for embedded
processors: soft processors like MicroBlaze or ARM Cortex-Mx when a microcontroller is needed,
and hard processors for higher performance applications.
Starting with PowerPC nearly 20 years ago, XILINX offers coherent embedded processing solutions from the
Zynq-7000 SoC (ARM Cortex-A9), Zynq US+ MPSoC (ARM Cortex-A53) and to the latest Versal ACAP
(Adaptive Compute Acceleration Platform with ARM Cortex-A72 processors).
This technical presentation gives a short overview of the latest exciting updates from XILINX: How does
XILINX expands its scalable portfolio with smaller Zynq US+ MPSoC’s ? How does integration in SoC’s go
further with high end Analog converters inside Zynq US+ RFSoC platforms? How is 7nm Versal ACAP more
than a SoC, designed for heterogeneous acceleration?
This session also aims at showing how XILINX wants to provide a new path to “Whole Application
Acceleration”, for any HW or SW engineer, with the KRIA K26 System On Module (SoM) and the ALVEO U30
Acceleration Card.

Speakers: Mr Gregory Donzel (Avnet Silica), Mr Marco Hoefle (Avnet Silica), Mrs Monique Ruch Cavin (Avnet Silica )

15:05 Microchip

Flash-based FPGA’s/SoC’s offer key differentiators for the electronics designers. Since 1985, ACTEL had been
serving markets for which power, safety, security and longevity are critical parameters. Acquired in 2010 by
MICROSEMI, it is now MICROCHIP since 2018. First FPGA company to embed hardened Cortex-Mx ARM
processors in their FPGA’s ten years ago, MICROCHIP innovates today with the PolarFire SoC.
The PolarFire SoC takes the best from the hardware features of the PolarFire FPGA, and enables Linux and
real-time applications, with hardened and open ISA platform RISC-V processors. This short presentation aims
at giving an overview of this new and unique SoC family. It also gives an opportunity to show how to start with
the PolarFire SoC devices and their associated tools.

Speakers: Mr Gregory Donzel (Avnet Silica), Mrs Monique Ruch Cavin (Avnet Silica)

15:45 Trenz

Using System-on-Modules (SoMs) has clear benefits, e.g. reduced development time and cost, upgradability, use
of widely tested designs and many more, but there are also drawbacks and pitfalls which have to be taken into
account during integration.
This talk will depict the advantages of different SoM series based on the Trenz Electronic product portfolio;
give hints for the choice of suitable SoMs for specific application from low-cost to high-end; show how
disadvantages can be overcome by variation and customization; give a deeper insight into the SoM specific
hardware; discuss which issues have to be addressed during integration and how Trenz Electronic is going to
support and assist you during this process (free of charge). Furthermore we will give an introduction to our
online available documentation, reference designs and demos, the corresponding software tools and how to
use this for effective system development.
Summed up, the talk presents a comprehensive guide from product selection to successful hardware integration
of Trenz Electronic products into a customer System.

Speaker: Mr Martin Rohrmüller (Trenz Electronic GmbH)

20210607_Trenz_CERN_presentation.pdf

16:40 Enclustra

FPGA-based System on Modules (SOM) combine all relevant parts to build an embedded system. They help
reducing development time and risk as well as total cost of ownership by a significant amount. SOMs offer many
advantages over chip-down designs. The high production quantity of off-the-shelf modules reduces their cost
and at the same time provide a proven and reliable solution with a large ecosystem. Enclustra develops and
sells its own off-the-shelf FPGA/SoC modules and IP Solutions and offers development services to customers –
since more than 15 years ago.
This presentation gives an overview of the large SOM product portfolio of Enclustra with more than 20 SOM
series and over 70 models. With three different product families, modules based on devices from Xilinx (Zynq
& Zynq UltraScale+ MPSoC), Intel (Cyclone V SoC & Arria 10 SoC) and soon Microchip (PolarFire
SoC), an Enclustra SOM for almost all applications is available.
Equally important as the module is the ecosystem to speed up the design-in of the module into the application.
The second part of the talk focuses on tools and support to get the job done. Amongst others, the following
topics are covered: Reference Designs, Board Support Packages (BSP/Linux) and debugging options. Application Notes, footprints, user schematics,
pinouts in Excel, IO net length, MTBF reports, 3D models and heat sink solutions.

Speakers: Mr Aimad Rhatay (Enclustra), Mrs Diana Ungureanu (Enclustra)

15:15 SoC-based Monitoring and Configuration of the ATLAS L1Calo TREX Module

As part of the ATLAS Level-1 Calorimeter trigger (L1Calo) Phase-I upgrade, the Preprocessor system is being extended with new Tile Rear Extension (TREX) modules.
For every bunch-crossing, the TREX provides digitized energy data from the Tile hadronic calorimeter to the new L1Calo feature extractor processors via high-speed optical links at 11.2 Gbps.
The TREX is equipped with a Kintex Ultrascale and 4 Artix-7 FPGAs, as well as with a Zynq Ultrascale+ MPSoC. The slow-control monitoring is carried out on the processing system (PS) running a CentOS 7 based operating system with an OPC UA server. The programmable logic (PL) is used to configure the on-board devices and FPGAs as well as an interface to VME. The Zynq MPSoC acts as a JTAG master for configuring the FPGAs and the SPI flash memories.
This contribution presents the functionality and the design choices of the SoCs on the TREX boards and the module operation in ATLAS.

15:45 SoC Developments for the Detector Control System of ATLAS Tile Calorimeter at the HL-LHC

The Tile Calorimeter (TileCal) is part of the ATLAS detector and is the central hadronic calorimeter. The Tile PreProcessor (TilePPr) is the core of the TileCal off-detector electronics for High luminosity LHC. The TilePPr is composed of several FPGA-based boards to operate and readout the on-detector electronics. As part of the TilePPr module, the Gigabit Ethernet switch (TileGbE) mezzanine board provides network communication to the different submodules, and the Tile Computer on Module (TileCoM) mezzanine is to be used to remotely configure the on-detector electronics and TilePPr FPGAs as well as, to interface the ATLAS DCS system providing monitoring data. This contribution presents the progress on the hardware and software design for the TileCoM as well as integration plans with the TilePPr to remotely control, configure and monitor the Tile Calorimeter Phase-II upgrade. A test bench which includes an Avnet Ultra96-V2 ZYNQ UltraScale+ MPSoC evaluation board and Tile Gigabit Ethernet switch will serve as a basis for the TileCoM mezzanine board as part of the Tile PreProcessor (TilePPr). Two OPC-UA servers will be implemented on the evaluation board to read data and publish it to the clients of the DCS. The first server that is currently implemented will read the Xilinx Analog-to-Digital Converter (XADC) data and, it will be used as a generic project for other ATLAS XADC projects. The second OPC-UA server will also be implemented on the TileCoM which will acquire data from the Compact Processing Module (CPM) through the IPbus and publish the acquired data to the DCS.

16:15 The Zynq MPSoC in the gFEX Hardware Trigger in ATLAS

The Global Feature Extractor (gFEX) is a hardware module that will be installed in the Phase-I Upgrade of the ATLAS experiment to maximise the trigger capabilities and flexibility for selecting events containing large-radius jets, typical of Lorentz-boosted objects. The gFEX makes use of a single module to cover the entire pseudorapidity range of the ATLAS calorimeter. This allows for event-based local pileup suppression and calculation of global quantities such as missing energy. The gFEX board hosts three Vertex Ultrascale+ FPGAs and a Zynq Ultrascale+ SoC used for data management, control, and monitoring of the board. The SoC is loaded with a customized Operating System (OS) built using the Yocto Project with the custom layer meta-l1calo. This talk will discuss the usage and integration of PYNQ software libraries for the gFEX custom hardware, the OPC-UA integration of DCS and the management of IPMC monitoring, and prospective capabilities of the Zynq to run increasingly better classification algorithms utilizing the unique strengths and resources of the SoC layout.

17:00 SoCs for Detector Controls and their Applications

SoCs are getting adopted extensively by ATLAS systems for the local control and monitoring of their back-end electronics due to their flexibility towards the hardware through the programmable logic but also the convenience provided for higher level software within the linux platform running on the processing system. OPC UA is the de facto middleware standard for Detector Controls at CERN and quasar framework makes the development of servers using OPC UA easy and efficient, resulting in solutions for a wide and diverse range of SoC-based applications. A common solution for the controls, the Embedded Monitoring Processor (EMP), is a SoM-based device, that is mainly used to interface LpGBT links to the experiments controls network via dedicated quasar servers.
In this contribution, a summary of the SoC projects in ATLAS that foresee the adoption of OPC UA and the latest news on the quasar framework for SoCs will be presented. Finally, the activities around the development of the EMP device and its usage will be highlighted.

17:30 SoC-based DAQ for the Pixel Readout Chip RD53a/b

The RCE (Reconfigurable Cluster Element) platform is a general-purpose system-on-chip data acquisition system, varying from a compact standalone bench-top form to ATCA compliant system. It is broadly deployed by several experiments, such as ATLAS, LCLS, LSST, HPS, and ProtoDUNE. We present a new generation bench-top RCE system, including a Xilinx UltraScale+ MPSoC board and a custom FMC adaptor card for the RD53 integrated circuit, which is a pixel readout chip for the Phase II upgrade of ATLAS and CMS. A high-performance RD53a/b chip calibration software is implemented to fit the ARM CPU environment.

18:00 Waveform Digitizing and Processing Front-end Microelectronics for large Experiments

In this talk, we will cover the development of a variety of SoC type high speed waveform digitizers designed with modularity in mind for large experiments. These microchips digitize, readout and process regions of interest of waveforms at 1-12 GSa/s at power and size constraints desired for particle physics applications. The chips are normally divided into 3 sections: analog input stages, mixed signal sampling, storage and digitization stages and a digital stage that performs semi-autonomous control of the mixed signal mechanisms. We will present preliminary results and a path forward to ultimate solutions that will may be interesting for LHC.

13:30 A System-on-Chip-based Front-end Electronics Control System for the Phase-2 ATLAS Thin-Gap Chambers (TGC)

In the phase-2 front-end system of the ATLAS Thin-Gap Chambers (TGC), a System-on-Chip(SoC)-based control module (JATHub) will take responsibility for the service and calibration around the frontend processing board (PS-board): (1) Configuration and soft error mitigation of the PS-Board FPGA, and (2) the clock phase monitoring, measurements, and alignment for high-performance hit BC assignment on PS-Boards. System-level commissioning has been launched at KEK, using prototype boards of JATHub and PS-Board. The functionality of configuration and recovery of the frontend FPGA has been successfully implemented and demonstrated in the test-bench system. The timing calibration methodology for fine-tuning of the clock phase has been developed around the JATHub, which exceeds the required timing resolution for the TGC trigger operation.

14:30 Remote Management of SoC-based Radiation Monitors both at CERN and ESS

CROME is CERN new RadiatiOn Monitoring Electronics. The system will homogenize both the radiation protection and environmental monitoring by end of LS3. Currently installed at the PSB, PS, SPS, SM18 and the North Area at CERN, CROME system encompasses a new generation of radiation detectors, alarm units, uninterruptible power supplies and interlock signal aggregators.
Most of our equipment are operated by Zynq SoCs. For the radiation detector, the FPGA part of the SoC collects and processes data from various sensors, executes various algorithms, take decisions every 100ms and transfers the results to the processing system. In parallel, all safety critical measurement are sent by the processing system in real-time to the SCADA supervision using the ROMULUS protocol.
On the other hand, the interlock aggregator's SoC collects interlocking statues provided by 2 fully redundant CPLD and send the information to the CERN control centre using the same protocol.
After giving a general architecture overview of our SoC based equipment, we will focus in this presentation on :
• remote firmware management of 200 operational devices
• on the TCP/IP ROMULUS protocol that we have developed to control our SoCs
• the simulator that we have developed to perform test scale tests
We will conclude with a tangible example (live demo ?) of ESS experience with CROME SoCs integration into EPICS using the ROMULUS protocol.

15:45 ZynqMP-based Board Management Mezzanines for the Serenity ATCA Blades

In the context of the CMS Phase-2 tracker back-end processing system, two mezzanines based on the Zynq Ultrascale+ Multi-Processor System-on-Chip (MPSoC) device have been developed to serve as centralized slow control and board management solution for the Serenity-family ATCA blades.
The Serenity family consists of two ATCA-sized boards designed to explore alternative configurations. Serenity-A is designed around a single Virtex US+ FPGA with up to 128 high-speed transceivers and an integrated slow-control and board management MPSoC mezzanine in the "FMC+" format. Serenity-Z contains two sites that utilize Samtec z-ray interposer technology mounting removable FPGA-based daughter cards. The choice of slow-control and board management is flexible between the combination of a Com-EXpress (CMX) Computer-on-Module (CoM), a DIMM-based IPMC, or an integrated MPSoC mezzanine in the "CMX-Extended" format.
In this talk, we present the current revision of both Serenity baseboards and the developments on the MPSoC mezzanines to execute the Intelligent Platform Management Controller (IPMC) software "OpenIPMC" in the real-time processors of the MPSoC. OpenIPMC, upon shelf approval, enables the main power and launches CentOS-based Linux in the application processors of the MPSoC. Furthermore, recent qualification tests of the OpenIPMC software against the PICMG standard will be shown.

16:15 Development Infrastructure for MPSoc/RFSoC Platforms

We utilize MPSoC/RFSoC devices for various applications, including slow control for the CMS experiment (MPSoC), readout of superconducting sensors (MPSoC), and control of quantum bits (RFSoC). The major advantage of MPSoC architectures is the feasibility of flexible and custom hardware-software partitioning. This flexibility comes for the price of additional system complexity. In this contribution, we present our applications and approach to develop SoC firmware for our applications. Based on gRPC, we developed a modular remote procedure call framework that gives flexible network access to the platform. Our Yocto tool flow includes building the FPGA firmware automatically. We also set up an environment that allows unit-testing of firmware modules and a system test framework utilizing MPSoC platforms to test complex hardware/software setups automatically. Integration of other lab devices such as oscilloscopes is possible and allows to include DAC/ADC interfaces in the test. The remote access, in combination with the automatic build and test, made a CI integration possible.

17:00 APx Embedded Linux Developments

Our talk will cover various aspects of Embedded Linux on SoC devices in the APx environment. The APx environment is a family of FPGA cards in the ATCA form factor, for trigger processing and DAQ readout in the CMS detector. The Embedded Linux environment operates on a Xilinx ZYNQ SoC-based mezzanine called the ELM# (currently a ZYNQ-7000 based ELM1 and a ZYNQ UltraScale+ based ELM2 exist). In this talk, we will discuss the APx CentOS framework's current model for management and configuration of our ZYNQ SoCs. This will include a discussion of software deployment, configuration management, geographic IP address assignment, and peripheral identification & mapping. We will outline our current support requirements for both development lab and final production environments, as well as what we would like to see from central IT departments relative to support for embedded linux as an ongoing matter. We will also discuss some limitations we have faced relative to geographic address assignment, and our plans for future work.

In this tutorial, we show how to integrate the Reliable Booting and Upgrade mechanisms into your own Zynq Ultrascale+ MPSoC project. The tutorial consists of PetaLinux recipe modifications, and Reliable Booting and Upgrade Linux service installation and configuration. Finally, we test the Reliable Booting system by introducing some failure scenarios, and we will see how the mechanisms can recover the Zynq MPSoC and bring it to a well-known state.The upgrade of the CMS DAQ system involves the installation of new electronics that will also host the Zynq Ultrascale+ MPSoC from Xilinx (Multiprocessor Systems on a Chip). The Zynq Ultrascale+ MPSoC will run control and monitoring software on a Linux operating system (OS).

14:00 ATLAS TDAQ Online Software Plans for SoC

We are presenting use cases and high-level functional requirements for a DAQ-to-SoC system communication layer, SoC–DAQ Interface or SoC–DAQI.
It is anticipated that SoCs will play a major role in configuration, control and monitoring of custom ATCA boards of the ATLAS Phase-II subsystems. This implies integration of SoC with TDAQ software infrastructure. The mechanism for this integration is a software layer which allows command and data exchange between SoC and a DAQ application, which is a part of the distributed Run Control tree controlling a data-taking session. A single customized DAQ application serves as a bridge between the DAQ world and a number of subsystem SoCs, using SoC–DAQI library to send commands to applications running on SoCs, process them there and return a result to the DAQ application. In addition to parameters, a command may include arbitrary payload, and the data returned by SoC may also contain a payload.
An implementation of SoC–DAQI is foreseen to be lightweight and on the SoC (server) side to be independent from TDAQ s/w and to rely only on s/w packages available in standard repositories for SoC Operating System, thus not imposing any additional requirements or restrictions on the TDAQ s/w design coming from the SoC architecture.
