This work considers a tool for simulating single event transients produced by ground level radiation in VDSM ICs. Fault injection procedures and a fast fault simulation algorithm for transient faults were implemented around an event driven simulator. A statistical analysis was implemented to organize data sampled from simulations. The performance evaluation of the algorithm shows that for a lar...

The increasing complexity of processors allied to the continuous technology shrink is making multicore-based systems more susceptible to soft errors. The high cost and time inherent to hardware-based fault injection approaches make the more efficient simulation-based fault injection frameworks crucial to test reliability. This paper proposes a fast, flexible fault injector framework which suppo...

Resistive bridging faults in combinational CMOS circuits are studied in this work. Circuit-level models are abstracted to voltage behavior for use in voltage-level fault simulation and test generation. Fault simulation is done using different test sets in order to study their effectiveness. Test generation is done to detect the highest possible bridging resistance for each fault. Different test...

in this study, detection and identification of common faults in industrial gas turbines is investigated. we propose a model-based robust fault detection(fd) method based on multiple models. for residual generation a bank of local linear neuro-fuzzy (llnf) models is used. moreover, in fault detection step, a passive approach based on adaptive threshold is employed. to achieve this purpose, the a...

An improved fault simulation environment is described in this paper, and details of its faulting capability are presented and tested. The versatility of our fault simulator in handling different fault models by adding new activity functions to our modeling structure such as n-terminal bridge faults is shown. We use our TUFTsim simulator, which is based on concurrent simulation algorithms to eff...

Fault simulation constitutes an indispensable tool in ensuring the correctness and quality of manufactured digital designs. Traditional uniprocessor based algorithms for fault simulation have been observed to be agonizingly slow for today's large and complex digital designs. More recently, a few researchers introduce an approach, as evident in the literature, wherein the fault set is partitione...

In this paper, we explore the implementation of fault table generation on a Graphics Processing Unit (GPU). A fault table is essential for fault diagnosis and fault detection in VLSI testing and debug. Generating a fault table requires extensive fault simulation, with no fault dropping, and is extremely expensive from a computational standpoint. Fault simulation is inherently parallelizable, an...
