Download or read book Fault Tolerant Design Implementation on Radiation Hardened by Design SRAM Based FPGAs written by Frank Hall Schmidt (Jr.) and published by . This book was released on 2013 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: SRAM-based FPGAs are highly attractive for space applications due to their in-flight reconfigurability, decreased development time and cost, and increased design and testing flexibility. The Xilinx Virtex-5QV is the first commercially available Radiation Hardened By Design (RHBD) SRAM-based FPGA; however, not all of its internal components are hardened against radiation-induced errors. This thesis examines and quantifies the additional considerations and techniques designers should employ with a RHBD SRAM-based FPGA in a space-based processing system to achieve high operational reliability. Additionally, this work presents the application of some of these techniques to the embedded avionics design of the REXIS imaging payload on the OSIRIS-REx asteroid sample return mission.

Book excerpt: Research on radiation-tolerant electronics has increased rapidly over the past few years, resulting in many interesting approaches to modeling radiation effects and designing radiation-hardened integrated circuits and embedded systems. This research is strongly driven by the growing need for radiation-hardened electronics for space applications, high-energy physics experiments such as those on the Large Hadron Collider at CERN, and many terrestrial nuclear applications including nuclear energy and nuclear safety. With the progressive scaling of integrated circuit technologies and the growing complexity of electronic systems, their susceptibility to ionizing radiation has raised many exciting challenges, which are expected to drive research in the coming decade. In this book we highlight recent breakthroughs in the study of radiation effects in advanced semiconductor devices, as well as in high-performance analog, mixed signal, RF, and digital integrated circuits. We also focus on advances in embedded radiation hardening in both FPGA and microcontroller systems and apply radiation-hardened embedded systems for cryptography and image processing, targeting space applications.

Download or read book Reconfigurable Field Programmable Gate Arrays for Mission Critical Applications written by Niccolò Battezzati and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embedded systems applications that are either mission or safety-critical usually entail low- to mid- production volumes, require the rapid development of specific tasks, which are typically computing intensive, and are cost bounded. The adoption of re-configurable FPGAs in such application domains is constrained to the availability of suitable techniques to guarantee the dependability requirements entailed by critical applications. This book describes the challenges faced by designers when implementing a mission- or safety-critical application using re-configurable FPGAs and it details various techniques to overcome these challenges. In addition to an overview of the key concepts of re-configurable FPGAs, it provides a theoretical description of the failure modes that can cause incorrect operation of re-configurable FPGA-based electronic systems. It also outlines analysis techniques that can be used to forecast such failures and covers the theory behind solutions to mitigate fault effects. This book also reviews current technologies available for building re-configurable FPGAs, specifically SRAM-based technology and Flash-based technology. For each technology introduced, theoretical concepts presented are applied to real cases. Design techniques and tools are presented to develop critical applications using commercial, off-the-shelf devices, such as Xilinx Virtex FPGAs, and Actel ProASIC FPGAs. Alternative techniques based on radiation hardened FPGAs, such as Xilinx SIRF and Atmel ATF280 are also presented. This publication is an invaluable reference for anyone interested in understanding the technologies of re-configurable FPGAs, as well as designers developing critical applications based on these technologies.
Download or read book FPGA Fault Tolerance in Radiation Environments written by Jáno Gebelein and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The constantly increasing memory density and performance of recent Field Programmable Gate Arrays (FPGA) has boosted a usage in many technical applications such as particle accelerators, automotive industry as well as defense and space. Some of these fields of interest are characterized by the presence of ionizing radiation as caused by natural decay or artificial excitation processes. Unfortunately, this type of radiation affects various digital circuits, including transistors forming Static Random Access Memory (SRAM) storage cells that constitute the technology node for high performance FPGAs. Various digital misbehavior in temporal or permanent manner as well as physical destruction of transistors are the consequence. Therefore, the mitigation of such effects becomes an essential design rule when using SRAM FPGAs in ionizing radiation environments. Tolerance against soft errors can be handled across various layers of modern FPGA design, starting with the most basic silicon manufacturing process, towards configuration, firmware, and system design, until finally ending up with application and software engineering. But only a highly optimized, joint concept of system-wide fault tolerance provides sufficient resilience against ionizing radiation effects without losing too much valuable device resources to the safety approach. This concept is introduced, analyzed, improved and validated in the present work. It includes, but is not limited to, static configuration scrubbing, various firmware redundancy approaches, dynamic memory conservation as well as state machine protection. Guidelines are given to improve manual design practices concerning fault tolerance and tools are shown to reduce necessary efforts. Finally, the SysCore development platform has been maintained to support the recommended design methods and act as Device Under Test (DUT) for all particle irradiation experiments that prove the efficiency of the proposed concept of system-wide fault tolerance for SRAM FPGAs in ionizing radiation environments.

Download or read book Electronics System Design Techniques for Safety Critical Applications written by Luca Sterpone and published by Springer Science & Business Media. This book was released on 2008-10-10 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is exactly “Safety”? A safety system should be defined as a system that will not endanger human life or the environment. A safety-critical system requires utmost care in their specification and design in order to avoid possible errors in their implementation that should result in unexpected system’s behavior during his operating “life”. An inappropriate method could lead to loss of life, and will almost certainly result in financial penalties in the long run, whether because of loss of business or because the imposition of fines. Risks of this kind are usually managed with the methods and tools of the “safety engineering”. A life-critical system is designed to 9 lose less than one life per billion (10 ). Nowadays, computers are used at least an order of magnitude more in safety-critical applications compared to two decades ago. Increasingly electronic devices are being used in applications where their correct operation is vital to ensure the safety of the human life and the environment. These application ranging from the anti-lock braking systems (ABS) in automobiles, to the fly-by-wire aircrafts, to biomedical supports to the human care. Therefore, it is vital that electronic designers be aware of the safety implications of the systems they develop. State of the art electronic systems are increasingly adopting progr- mable devices for electronic applications on earthling system. In particular, the Field Programmable Gate Array (FPGA) devices are becoming very interesting due to their characteristics in terms of performance, dimensions and cost.
Download or read book FPGA SRAM Soft Error Radiation Hardening written by Gabriel Torrens and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to integrated circuit technology scaling, a type of radiation effects called single event upsets (SEUs) has become a major concern for static random access memories (SRAMs) and thus for SRAM-based field programmable gate arrays (FPGAs). These radiation effects are characterized by altering data stored in SRAM cells without permanently damaging them. However, SEUs can lead to unpredictable behavior in SRAM-based FPGAs. A new hardening technique compatible with the current FPGA design workflows is presented. The technique works at the cell design level, and it is based on the modulation of cell transistor channel width. Experimental results show that to properly harden an SRAM cell, only some transistors have to be increased in size, while others need to be minimum sized. So, with this technique, area can be used in the most efficient way to harden SRAMs against radiation. Experimental results on a 65-nm complementary metal-oxide-semiconductor (CMOS) SRAM demonstrate that the number of SEU events can be roughly reduced to 50% with adequate transitory sizing, while area is kept constant or slightly increased.

Download or read book Detection of Configuration Memory Upsets Causing Persistent Errors in SRAM based FPGAs written by and published by . This book was released on 2004 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: FPGA designers are becoming increasingly aware of fault tolerance issues in modern FPGA designs, especially designs destined for a radiation environment. We classify errors due to upsets within the configuration bitstream into two categories; namely, persistent and non-persistent. Persistent errors generally cannot be tolerated. However, non-persistent errors can be tolerated in certain types of designs as long as they are properly accounted for. We discuss situations in which nonpersistent errors are acceptable, and describe a technique for the detection of upsets causing persistent errors within the configuration memory of an SRAM-based FPGA.
