The concern for soft errors is not overblown
IEEE International Conference on Test, 2005., 2006Single event upsets in logic paths are an emerging concern for computing systems built in advanced CMOS technologies. Upset rates for latches used in sequential circuits are increasing, and combinatorial circuit elements will also become a factor for future technology nodes.

Modeling the Propagation of Soft Errors in Programs
Proceedings of the 2nd International Conference on Computer Science and Software Engineering, 2019Due to the continuous growth of transistors in processors, the cloud computing paradigm and increasingly complex environment, soft errors, which are a category of typical transient errors, have become an urgent challenge in ground-level systems. To handle these errors, making clear the error propagation is the key step.

Enhancing I2C robustness to soft errors
2017 IEEE 8th Latin American Symposium on Circuits & Systems (LASCAS), 2017This paper proposes the use of a I2C Bus Monitor core able to perform data integrity verification activities, to signalize metrics about the quality of communications, to detect transient faults and permanent errors on the bus and to act on the devices connected to the bus for the recovery of such errors avoiding failures.

On Soft Error Immunity of Sequential Circuits
2010 19th IEEE Asian Test Symposium, 2010With technology scaling, radiation-induced soft error has been a major concern even for mainstream enterprise applications. Since various hardening solutions impose significant costs in performance, area and power consumption, full soft error protection can hardly satisfy the multiple design goals simultaneously.

2010 IEEE 25th International Symposium on Defect and Fault Tolerance in VLSI Systems, 2010
This paper presents a construction of a flip-flop (FF) that works as a soft error tolerant FF in system operations and as a BILBO (Built-In Logic Block Observer) FF in manufacturing testing. The construction of the proposed FF is based on that of an existing soft error tolerant FF, namely a BISER (Built-In Soft Error Resilience) FF.

SIMD-based soft error detection
Proceedings of the ACM International Conference on Computing Frontiers, 2016Soft error rates in processors have been increasing with decreasing feature size and larger chips. Software-only solutions have been proposed to deal with this problem, for instance via instruction duplication. However, this leads to significant overheads in performance and energy.

Managing Soft-Errors in Transactional Systems
2014 IEEE International Parallel & Distributed Processing Symposium Workshops, 2014Multicore architectures are becoming increasingly prone to soft-errors – i.e., transient faults caused by external physical phenomena such as electric noise and cosmic particle strikes. With increasing core counts, the soft-error rate is growing due to the accelerating transistor density on chips.

Effects of Soft Error to System Reliability
2011 IEEE Workshops of International Conference on Advanced Information Networking and Applications, 2011Soft errors on hardware could affect the reliability of computer system. To estimate system reliability, it is important to know the effects of soft errors to system reliability. This paper explores the effects of soft errors to computer system reliability. We propose a new approach to measure system reliability for soft error factor.

An Experimental Study of Soft Errors in Microprocessors
IEEE Micro, 2005The issue of soft errors is an important emerging concern in the design and implementation of future microprocessors. The authors examine the impact of soft errors on two different microarchitectures: a DLX processor for embedded applications and a high-performance alpha processor.
