Abstract
A test waveform generator comprises a storage unit (1a , 1b) for storing timing information; a timing generator unit (2a, 2b) to which the timing information is input from the storage unit and which is adapted to output a timing pulse at a predetermined time on the basis of the timing information; and a waveform generating unit (3, 4) to which the pulse from the timing generator unit is input and which is adapted to output a test waveform. The timing generator unit is arranged so that the timing of the timing pulse is set with either (1) a period clock signal (CLK) serving as a reference or (2) another timing pulse serving as a reference.
