Abstract

This paper describes experiments conducted to estimate how the use of (area-demanding) virtual reconfigurable circuits (VRC) influences the dependability of FPGA-based evolvable systems. It is shown that these systems are not so sensitive to faults as their area-demanding implementations could evoke. Evolutionary techniques are utilized to design fault tolerant circuits in a virtual reconfigurable circuit and to perform their automatic functional recovery in case of occurence of faults in a configuration memory of FPGA. All the experiments are performed on models of reconfigurable devices. This paper does not claim that the use of the VRC improves the dependability; it shows how the use of VRCs could influence the dependability.
