Towards self-configuring evolvable FPGA using feedback cross-checking

Abstract

Evolvable hardware supposedly avoids single point of failure in circuitry. However, its control circuit is currently separate, thus a single point of failure exists in their interface. In contrast, we implement self-maintaining circuits in a faulty field programmable gate array simulation. We evaluate these circuits with respect to diagnosis reliability and reconfiguration performance. An implementation of our model could increase the survivability of critical engineering applications. © Springer-Verlag Berlin Heidelberg 2006.
