Abstract

An FPGA-based hardware emulation system is shown to boost the speed of fault simulation for sequential circuits. The circuit downloaded into the emulation system which emulates the faulty circuit's behavior is synthesized from the good circuit and the given fault list in a novel way. Fault injection is made easy by shifting the content of a fault injection chain, with which we get rid of the highly time-consuming bit-stream regeneration process. Experimental results for ISCAS-89 benchmark circuits show that the fault emulator is about twenty times faster than HOPE (a parallel fault simulator). A parallel fault emulation approach is also proposed, in which faults that are not activated or with short propagation distance are screened off before fault emulation, and non-stem faults are collapsed into their equivalent stem faults, further reducing the number of faults actually emulated.
