We propose a novel C-testable technique for the fast-Fourier-transform (FFT) networks. Only 18 test patterns are required to achieve 100% coverage of combinational single cell faults and interconnect stuck-at faults for the FFT network. A fault tolerant design for the FFT network also has been proposed. Compared with previous results, our approach has higher reliability and lower hardware overhead - only three spare bit-level cells are needed for repairing a faulty row in the multiply-subtract-add (MSA) module, and special cell design is not required to implement the reconfiguration scheme. The hardware overhead is low - about 4% for 16-bit numbers regardless of the FFT network size.
