Intrinsic Evolution for Synthesis of Fault-Recoverable Circuit (Special Section on VLSI Design and CAD Algorithms)

概要

This paper presents an evolutionary technique to build and maintain fault-recoverable digital circuits. As the synthesis of a circuit by genetic algorithm is progressed according to the circuit behavioral objectives and interactions with the environments, the knowledge regarding the architecture as well as the placement and routing processes is not the major concern of the proposed method. The evolutionary behavior of the circuit also prevents the circuit from stuck-at faults by continuously modifying the neighboring circuit blocks accordingly. This is done without the prior knowledge of where and how the faults occur because of the evolutionary nature. Thus, the overhead circuit blocks for fault diagnosis and redundancy are minimized with this design. The fault-recoverable evolvable hardware circuits are synthesized to build a few combinational logics by evolution and the fault recovery capabilities are shown with the reconfigurable FPGA.
