Abstract
An IC measuring device constituted by a first timing generator (TG) for outputting a pair of judgment strobe pulses (S); a first edge detector (E) for detecting the states of a data strobe (DCK) at two time points within one test cycle on the basis of the pair of judgment strobe pulses (S); a second timing generator (TG) for outputting a pair of judgment strobe pulses (S); a second edge detector (E) for detecting the states of data at two time points within one test cycle on the basis of the pair of judgment strobe pulses (S); and a judgment section (J) for determining acceptance/rejection of the timing of the data with reference to the data strobe on the basis of the states of the data and the states of the data strobe.
