  • Patent number: 7460988
    Abstract: There is provided a test emulator for emulating a test apparatus including a plurality of test modules for supplying test signal to devices under test respectively, including: a plurality of test module emulation sections for emulating the plurality of test modules generating the test signal based on different cycles, a control emulation section for emulating a control apparatus for controlling the test of the devices under test, a synchronous emulation section for generating test signal generating timings, at which each of the plurality of test module emulation sections is to generate the test signal in simulation corresponding to cycle time of the test module emulation section, based on instructions from the control emulation section, a timing alignment section for aligning the plurality of test signal generating timings generated by the synchronous emulation section in order of time, and outputting them one by one, and a schedule section for causing the test module emulation section corresponding to one of

  • Publication number: 20020193980
    Abstract: A semiconductor test program debugging apparatus is provided which generates, in a simulatory manner, a signal that a DUT should output when receiving a test signal, and which generates, in a simulatory manner, an analog waveform that should be output from the analog output terminal, when an analog waveform acquisition instruction that is included in a semiconductor test program has been executed.
