Detection of ESD-induced soft errors
… correlation between the voltage disturbance and soft errors induced is identified. The threshold for such disturbances is found. The results are validated across multiple chips. Memory elements are found to be more immune than registers.

Developing a multi-level fault injection environment
… state of the system to change, which might cause errors to the system with non-negligible probability. Such errors are termed "soft errors". Bit flips in the design are good way to model these soft-errors. These bit-flips due to soft errors are random and transient in a design, making their …

Monte Carlo Methods for Reliability Analysis and Power Estimation
… dissipation causes overheating and can lead to soft errors and permanent damage, attempts to achieve first-pass reliability require accurate and efficient power estimation. With today's closer customer interaction, many circuits are being designed for already existing systems or for systems that …

Soft-error resilient on-chip memory structures
Soft errors induced by energetic particle strikes in on-chip memory structures, such as L1 data/instruction caches and register files, have become an increasing challenge in designing new generation reliable microprocessors. Due to their transient/random nature, soft errors cannot be captured by …

SoftECC : a system for software memory integrity checking
SoftECC is software memory integrity checking agent. SoftECC repeatedly computes page-level checksums as an efficient means to verify that a page's contents have not changed. Memory errors that occur between two checksum computations will cause the two checksum values to disagree. Legitimate memory …
