TEST DEVICE AND TEST METHOD |
摘要 |
<p>There is provided a testing device including: a first signal comparator operable to acquire a value of an output pattern based on a result that is obtained by comparing a voltage of an output signal and a first threshold value voltage in a first strobe timing, in order to acquire a first output pattern sequence; a second signal comparator operable to acquire a value of an output pat tern based on a result that is obtained by comparing a voltage of an output signal and a second threshold value voltage in a second strobe timing, in order to acquire a second output pattern sequence; a header pattern sequence detecting unit operable to detect that the first output pattern sequence is identical with a header pattern sequence; and an expectation comparing unit operable to output a comparison result between the second output pattern sequence acquired by the second signal comparator and an expectation pattern sequence when detecting a correspondence between the first output pattern sequence and the header pattern sequence.</p> |
