Abstract
A timing adjusting circuit is mounted on a semiconductor device. A reference signal TREFIN and signals TPa to TPx to be adjusted are supplied from a tester via transmission lines on a test jig. By gradually advancing phases of the signals TPa to TPx with respect to a trigger signal TRIG generated on the basis of the reference signal, the differences of transition timings of driver waveforms are held in a plurality of registers corresponding to the transmission lines. The data held by the plurality of registers is sent to the tester via a storage result outputting circuit. On the basis of the data, output timings of the driver waveforms can be adjusted by the tester with high accuracy.
