  Along with the complexity of electronic systems for safety-critical
applications, the cost of safety mechanisms evaluation by fault injection
simulation is rapidly going up. To reduce these efforts, we propose a fault
injection methodology where Hardware Description Language (HDL) code slicing is
exploited to accelerate transient fault injection campaigns by pruning fault
lists and reducing the number of the injections. In particular, the dynamic HDL
slicing technique provides for a critical fault list and allows avoiding
injections at non-critical time-steps. Experimental results on an industrial
core show that the proposed methodology can successfully reduce the number of
injections by up to 10 percent and speed-up the fault injection campaigns.
