Reliability Optimization of Reconfigurable FPGA Based on Second-Order Approximation Domain-Partition

The problem of planning the overlaps of multiple alternative configurations is critical to maximize the reliability of a reconfigurable fault-tolerant system based on field programmable gate arrays. To address the problem, an unnecessary assumption made in previous work is removed and a second-order approximation domain-partition method is proposed. Experimental results on ITC99 benchmark circuits demonstrate the proposed technique outperforms previous work in failure rate with less memory cost to store configurations.
