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

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 the test signal generating timings output by the timing alignment section to generate the test signal in simulation in the cycle time corresponding to the test signal generating timing.

       13 . A test apparatus comprising a test module for supplying a test signal to a device under test, comprising: 
 a control apparatus for controlling a test of the device under test;    a test module for generating a test signal based on a cycle; and    a test module emulation section for emulating said test module, wherein    said control apparatus inputs an instruction about which of a real test or a simulation test is to be selected for the test of the device under test,    said control apparatus supplies said test module with a test program for testing the device under test and causes said test module to test the device under test when the instruction indicates that the real test of the device under test is to be performed, and    said control apparatus supplies said test module emulation section with a test program for testing the device under test and causes said test module emulation section to simulate the test of the device under test when the instructions indicates that the simulation test of the device under test is to be performed.    
   
   
       14 . The test apparatus as claimed in  claim 13 , wherein 
 said control unit executes communication software for performing communication processing between said control unit and said test module, and    said communication software decides whether the test program is to be supplied to said test module or said test module emulation section based on the instructions included in calling for initializing the communication software in cooperation with said control apparatus.
