Resumen:
In this work, we evaluate the ability of Oscillation-Based Test (OBT)
for detecting in continuous-time filters, more realistic parametric faults. As a
case study, we consider a low pass fourth order leapfrog filter. We use a fault
simulation based on Monte Carlo and redefine a fault coverage metric to
globally characterized OBT. The fault model applied assumes that only one
component can be faulty while the others adopt random values within their
tolerance bands. Statistical deviations in the values of the fault-free components
are considered in order to obtain a more accurate evaluation of the test
technique under study. The fault coverage data obtained show high values only
for high deviation faults and presents significant differences for positive and
negative deviations. In addition, the metric also reveals that some of the
components of the filter under study can be considered as hard to test.
