We present a practical, systematical method for the evaluation of the soft error rate (SER) of microelectronic devices. Existing methodologies, practices and tools are integrated in a common approach while highlighting the need for specific data or tools. The showcased method is particularly adapted for evaluating the SER of very complex microelectronic devices by engineers confronted to increasingly...
Cryptographic devices are recently implemented with different countermeasures against side channel attacks and fault analysis. Moreover, some usual testing techniques, such as scan chains, are not allowed or restricted for security requirements. In this paper, we analyze the impact that error detecting schemes have on the testability of an implementation of the advanced encryption standard, in particular...
In many DSP applications (image and voice processing, baseband symbol decoding in high quality communication channels) several dBs of SNR loss can be tolerated without noticeable impact on system level performance. For power optimization in such applications, voltage overscaling can be used to operate the arithmetic circuitry slower than the critical circuit path delay while incurring tolerable SNR...
This document presents a compilation of results from tests performed by iRoC Technologies on SER induced by alpha particles on SRAM memories for technology nodes from 180 nm to 65 nm. The aim of this study is to establish the variation of sensitivity with technology node for SEU and MCU, and to analyze the possible influence of different designs and technological parameters at a given technology node.
The paper addresses the problem of creating a comprehensive fault injection environment, which integrates and improves various simulation and supplementary functions. This is illustrated with experimental results.
Soft errors caused by ionizing radiation have emerged as a major concern for current generation of CMOS technologies and the trend is expected to get worse. Soft error rate (SER) measurement, expressed as number of failures encountered per billion hours of device operation, is time consuming and involves significant test cost. The cost stems from having to connect a device-under-test to a tester for...
In this paper we present a low cost fault-tolerant attitude determination system to a scientific satellite using COTS devices. We related our experience in developing the attitude determination system, where we combine proven fault tolerance techniques to protect the whole system composed only by COTS from the effects produced by transient faults. We detailed the failure cases and the detection, reconfiguration...
