Metrics for the Measurement of the Quality of Stimuli in Radiation Testing Using Fast Hardware Emulation

Radiation Testing of unstructured digital circuits presents an extended set of difficulties related with detection and propagation of the faults to the primary outputs. Stimuli have to be chosen thinking on the possibility of propagating the faults through the logic to the primary outputs. Moreover, the set of stimuli should be selected to enhance the observability of both the time and location of the internal faults.
