Abstract :
This article proposes a new approach for an FPGA-based emulation system for IC fault diagnosis that incorporates three speedup techniques: circuit partitioning, fault-injection elements (using a novel design), and a fault-injection scan chain. Experimental results in terms of hardware overhead and emulation time for ISCAS-85 benchmark circuits are compared with previous works to highlight the 33× speedup and 44% reduced overhead of this proposed system.
