Radiation-induced soft errors are a major concern for modern digital circuits, especially memory elements. Unlike large Random Access Memories that can be protected using error-correcting codes and bit interleaving, soft error protection of sequential elements, i.e. latches and flip-flops, is challenging. Traditional techniques for designing soft-error-resilient sequential elements generally address single node errors, or Single Event Upsets (SEUs). However, with technology scaling, the charge deposited by a single particle strike can be simultaneously collected and shared by multiple circuit nodes, resulting in Single Event Multiple Upsets (SEMUs). In this work, we target SEMUs by presenting a design framework for soft-error-resilient sequential cell design with an overview of existing circuit and layout techniques for soft error mitigation, and introducing a new soft error resilience layout design principle called LEAP, or Layout Design through Error-Aware Transistor Positioning. We then discuss our application of LEAP to the SEU-immune Dual Interlocked Storage Cell (DICE) by implementing a new sequential element layout called LEAP-DICE, retaining the original DICE circuit topology. We compare the soft error performance of SEU-immune flip-flops with the LEAP-DICE flip-flop using a test chip in 180nm CMOS under 200-MeV proton radiation and conclude that 1) our LEAP-DICE flip-flop encounters on average 2,000X and 5X fewer errors compared to a conventional D flip-flop and our reference DICE flip-flop, respectively; 2) our LEAP-DICE flip-flop has the best soft error performance among all existing SEU-immune flip-flops; 3) In the evaluation of our design framework, we also discovered new soft error effects related to operating conditions such as voltage scaling, clock frequency setting and radiation dose.

This book describes the benefits and drawbacks inherent in the use of virtual platforms (VPs) to perform fast and early soft error assessment of multicore systems. The authors show that VPs provide engineers with appropriate means to investigate new and more efficient fault injection and mitigation techniques. Coverage also includes the use of machine learning techniques (e.g., linear regression) to speed-up the soft error evaluation process by pinpointing parameters (e.g., architectural) with the most substantial impact on the software stack dependability. This book provides valuable information and insight through more than 3 million individual scenarios and 2 million simulation-hours. Further, this book explores machine learning techniques usage to navigate large fault injection datasets.

This book evaluates the influence of process variations (e.g. work-function fluctuations) and radiation-induced soft errors in a set of logic cells using FinFET technology, considering the 7nm technological node as a case study. Moreover, for accurate soft error estimation, the authors adopt a radiation event generator tool (MUSCA SEP3), which deals both with layout features and electrical properties of devices. The authors also explore four circuit-level techniques (e.g. transistor reordering, decoupling cells, Schmitt Trigger, and sleep transistor) as alternatives to attenuate the unwanted effects on FinFET logic cells. This book also evaluates the mitigation tendency when different levels of process variation, transistor sizing, and radiation particle characteristics are applied in the design. An overall comparison of all methods addressed by this work is provided allowing to trace a trade-off between the reliability gains and the design penalties of each approach regarding the area, performance, power consumption, single event transient (SET) pulse width, and SET cross-section.

Due to shrinking feature size and significant reduction in noise margins, as we are moving into very deep sub-micron technology, circuits have become more susceptible to manufacturing defects, noise-related transient faults and interference from radiation. Traditionally, soft errors have been a much greater concern in memories than in logic circuits. However, due to technology scaling, logic circuits have become equally susceptible to soft errors. Moreover, enhanced usage of commercial off the shelf (COTS) electronic components for avionics has also increased the importance of analyzing soft errors in hardware circuits. Conventionally, understanding soft error glitches requires circuit level modeling, which requires information available only at late stages in the design flow. Instead of this approach some researchers have produced modeling techniques using Reduced Order Binary Decision Diagrams (ROBDD) and Algebraic Decision Diagrams (ADD), which does allow analyzing soft error at an earlier stage in design flow. In this thesis, a new methodology for modeling soft errors glitch propagation path using Multiway Decision Graphs is introduced. This modeling technique is applicable on both combinational and asynchronous circuits. The proposed glitch propagation path modeling technique jointly takes care of logical and electrical masking. Our methodology involves new ways of injecting glitches including glitch injection in feedback paths of asynchronous circuits. This work presents a complete framework to exhaustively provide all the possible sequences of signals that lead to the possibility of glitch propagation to the primary output in combinational and asynchronous circuits. In addition, a new tool is developed based on the proposed methodology called Soft Error Glitch-Propagating Path Finder (SEGP-Finder) to automate the identification of these sequences of signals. This work helps designers identify the vulnerable circuit paths at the logic abstraction level. Also, this methodology allows designers to apply radiation tolerance techniques on reduced sets of possibilities. By applying our methodology on different combinational and asynchronous circuits an improvement in terms of possible-fault injection vectors is observed. As an example, approximately 8% of all the possible input vectors and sequences is required for obtaining exhaustive glitch propagation path identification in a representative implementation of a bundled data asynchronous circuit. To the best of our knowledge, this is the first time MDG based decision diagram based soft error identification approach is proposed for combinational and asynchronous circuits.
