Abstract
There is provided a pattern generator which is capable of utilizing memory blocks connected to unused pins of a DUT. A pattern address from a vector generation control,and a control signal from a control table buffer,are used to control an address converter,to convert a pattern address PA into plural-bit addresses a, b and c. The address a or b is provided to m memory blocks,(m being an integral multiple of the number n of pins of the DUT) to generate therefrom pattern data. The pieces of pattern data thus outputted from the memory blocks are selected by sequence data from one of n sequence register, and the selected pattern data is applied to the corresponding pin of the DUT,after being converted by a frame processor,into a waveform suitable for application to the DUT.
