Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose fault-tolerant FPGA -IP cores for system LSI. Unlike discrete FPGAs, in
which the integration scale can be made relatively large, programmable IP cores must correspond to arrays of
various sizes. The key features of our architectures are regular tile structure, spare modules and bypass wires
for fault avoidance, and con guration mechanism for single-cycle recon guration. We also develop routing tools,
namely EasyRouter for proposed architecture. This tool can handle various array sizes corresponding to developed
programmable IP cores. In this evaluation, we compared the performances of conventional FPGA and the proposed
fault-tolerant FPGA architectures. On average, our architectures have less than 2.2 times the area and 1.3 times
the delay compared with conventional FPGA architectures. At the same time, conventional FPGAs cannot tolerate
faults, whereas our architectures perform with a 90% success rate in fault avoidance for a ratio of faulty tiles of 1%.
