Test emulator, test module emulator, and record medium storing program therein

A test apparatus for testing devices under test, the test apparatus including a system controller, an emulating apparatus and a plurality of test modules for supplying a test signal to each of devices under test, wherein the emulating apparatus comprises:

• a test module emulating apparatus;
• a control emulation section connected to the system controller, for controlling the test of the devices under test;
• a synchronous emulation section connected to the test module emulating apparatus, for generating a plurality of test signal generating timings, at which the test module emulating apparatus is to generate the test signal in simulation corresponding to cycle time of said test module emulating apparatus, based on instructions from said control emulation section;
• a timing alignment section connected to the synchronous emulation section, for aligning the plurality of test signal generating timings generated by said synchronous emulation section in order of time, and outputting them one by one;
• and
• a schedule section connected to the timing alignment section and the test module emulating apparatus, for causing said test module emulating apparatus corresponding to one of the test signal generating timings output by said timing alignment section to generate the test signal in simulation in the cycle time corresponding to the test signal generating timing,
• wherein the test module emulating apparatus comprises a pattern generator emulation section for generating the test signal in simulation in the cycle time corresponding to one of the test signal generating timings based on instructions from said schedule section.
