Abstract:This paper describes the evaluation of an
oscillation-based approach specially thought for testing a lowpower
analog system that monitors an implantable biomedical
device (intelligent stent). Fault simulation analysis has been
performed on the basic blocks of the CUT, and oscillation
parameters (frequency and amplitude) have been measured at
the output of the last system block, an oscillator. Taking
advantage of fault reflection from the rest of the blocks, the
proposed testing method will avoid the need of adding extra
circuitry to convert the different partitions of the CUT into
oscillators, reducing circuit complexity and possible performance
degradation. The results obtained show that a good fault
coverage figure for catastrophic faults can be achieved.
