Original Abstract

In this presentation, a methodology of FTS design based on FPGA is presented. The FT architectures are based both on duplex and TMR systems to which fault detection capabilities are added, the use of on-line checkers for this purpose is demonstrated. It is described how reliability and availability parameters in TMR and duplex structures with checkers can be increased. To demonstrate this, analytical calculations based on Markov reliability model are used. It is also shown how the availability parameters can be affected by the operating environment into which the FTS is implemented. Finally, the results of research and the comparison of our approach with classical TMR and duplex architectures for different failure rates are presented.
