A New Architectural-level Fault Simulation Using Propagation Prediction of Grouped Fault-eeects

A new technique is proposed to handle fault simulation at the architectural level. The technique bypasses the need for complete gate-level structure and ee-ciently uses the architectural information. Symbolic data representing groups of stuck-at faults, known as fault eeects, are propagated across the circuit with intelligent propagation prediction. Fault eeects may combine and form new groups ...

RT-level Fault Simulation Based on Symbolic Propagation

The rapid rise in size and complexity of VLSI circuits has stimulated a need to handle fault simulation at higher levels of abstraction. We outline an RT-level fault simulation techniqueion. We outline an RT-level fault simulation technique that utilizes symbolic data to group fault effects. Experimental results show that the proposed methodology provides superior speed-ups and accurate fault c...

Non-intrusive System Level Fault-Tolerance

High-integrity embedded systems operate in multiple modes, in order to ensure system availability in the face of faults. Unanticipated state-dependent faults that remain in software after system design and development behave like hardware transient faults: they appear, do the damage and disappear. The conventional approach used for handling task overruns caused by transient faults is to use a s...
