Patent ID: 7460988

Claim:
A computer readable medium storing therein instructions for causing a computer to function as an emulating apparatus, the emulating apparatus including a plurality of test modules for supplying a test signal to each of devices under test, the emulating apparatus comprising: a plurality of test module emulation sections configured to generate 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 connected to each of the plurality of test module emulation sections, for generating test signal generating timings, at which each of said plurality of test module emulation sections is to generate the test signal in simulation corresponding to cycle time of said test module emulation section, 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 emulation section, for causing said test module emulation section 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.
