Executive Summary

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. Field Programmable Gate Array (FPGA) devices have been widely used due to their flexibility and functionality merits. However, along with fast shrinking feature size, FPGA devices are more vulnerable to electro-migration.
