A new approach to fault emulation
R. Sedaghat-Maman, Erich Barke · 2002
Presents a hardware-based approach to fault emulation without a dedicated logic emulation system. Logic is introduced for fault injection in a targeted circuit. The logic emulator is expanded with additional hardware modules required for the fault emulation process. This method simulates the stuck-at fault model and may also be used for multiple faults and bridging faults. The implementation discussed in this paper is only for SSFs (single stuck-at faults). When tested on combinational circuits using a commercial emulator, speeds varying from a few kHz to several MHz were reached. The efficiency of this form of fault injection is illustrated by the experimental results presented in this paper.
