A method and architecture for synchronization of Fault-Tolerant system implemented in FPGAs is proposed. It is based on repairing faulty units and transferring of the fault-free state of the system to the unit under repair. Its architecture is based on the previously designed model which is extended for usage in more complex systems. The proposed method was implemented on an FPGA and the experimental...
Network communication algorithms development is presented in the paper, with the purpose to implement bio-inspired hardware systems which exhibit the abilities of living organisms, such as: evolution capabilities, self-healing and fault-tolerance. In the first steps of these research efforts an embryonic system with bi-dimensional FPGA-based artificial cell network is designed and tested through careful...
The cell-based structure, which makes up the majority of biological organisms offers the ability to grow with fault-tolerance abilities and self-repair. By adapting these mechanisms and capabilities from nature, scientific approaches have helped researches understand related phenomena and associated with principles to engine complex novel digital systems and improve their capability. Founded by these...

There are large subsets of digital circuits that are designed with bidirectional ports, like microprocessors, peripherals and certain communication circuits. During the design phase, the reliability of these circuits can be tested by means of fault injection. Traditional fault injection techniques have to arrange the design in order to perform the testing the bidirectional ports, because these tests...
When manufacturing nano-devices, defects are a certainty and reliability becomes a critical issue. Until now, the most pervasive methods used to address reliability, involve injecting spare resources. However, these methods use predetermined spare placement that is not optimized for each netlist. This is the first work (to the best of our knowledge) that addresses the problem of fault tolerance for...
We propose a built-in scheme for generating all patterns of a given deterministic test set T. The scheme is based on grouping the columns of T, so that in each group of columns the number ri of unique representatives (row subvectors) as well as their product R over all such groups is kept at a minimum. The representatives of each group (segment) are then generated by a small finite state machine (FSM)...
This paper presents an FPGA-based fault injection tool, called FITO that supports several synthesizable fault models for dependability analysis of digital systems modeled by Verilog HDL. Using the FITO, experiments can be performed in real-time with good controllability and observability. As a case study, an OpenRISC 1200 microprocessor was evaluated using an FPGA circuit. About 4000 permanent, transient,...
SRAM-based Field Programmable Gate Arrays (FPGAs) are becoming more and more popular among aerospace devices. Radiation effects have to be investigated in order to measure the fault tolerance degree of the applications and to validate new mitigation techniques. Fault injection is one of the possible evaluation methods. Several platforms have been developed in the past years in order to inject soft...
Reconfigurable logic devices such as SRAM-based field programmable gate arrays (FPGAs) are nowadays increasingly popular thanks to their capability of implementing complex circuits with very short development time and for their high versatility in implementing different kind of applications, ranging from signal processing to the networking. The usage of reconfigurable devices in safety critical fields,...
Bio-inspired hardware systems computer-aided modeling, simulation and experimental research are presented in the paper, with the purpose to design and experiment digital systems with abilities of biological organisms. Original model for an FPGA-based artificial cell provided also with strongly network communication behaviors and fault-tolerant operation mode is proposed and developed. The complex...
