Observation and/or failure inspection apparatus, method and program therefor

摘要

An observation apparatus according to one embodiment can include a timing generating unit ( 2 ) that generates a timing signal at a predetermined period. A sampling unit ( 3 ) can sample a current observation signal of a power supply current on the basis of the timing signal, and store sampled data in data storing unit ( 5 ). A data number adjusting unit ( 6 ) can adjust the number of data samples to a number that is a power of two. An arithmetic operating unit ( 4 ) can Fourier-transform the adjusted data to generate frequency spectrum results of the current observation signal. In addition, a failure inspection apparatus according to one embodiment analyzes the frequency spectrum of an integrated circuit under observation to determine a failure condition of the integrated circuit.
