Patent ID: 6892333

Claim:
An IC measuring device for determining acceptance or rejection of timing between a data strobe outputted from an IC to be measured and data outputted from the IC, the IC measuring device comprising: a first timing generator for outputting a pair of judgment strobe pulses at different times and in synchronism with a test cycle of the IC measuring device; a first edge detector for detecting states of the data strobe at two time points within one test cycle on the basis of the pair of judgment strobe pulses supplied by the first timing generator; a second timing generator for outputting a pair of judgment strobe pulses at different times and in synchronism with a test cycle of the IC measuring device; a second edge detector for detecting states of the data at two time points within one test cycle on the basis of the pair of judgment strobe pulses supplied by the second timing generator; and a judgment section for determining acceptance or rejection of timing of the data with reference to the data strobe on the basis of the states of the data detected by the second edge detector and the states of the data strobe detected by the first edge detector.
