    • A setting of a logical state in an integrated circuit is changed, a plurality of measurement patterns which are used in a quiescent power source current test of the integrated circuit are formed, an internal state value 0/1 of each net at the time when the measurement patterns are supplied by a simulation of the integrated circuit is derived, and further, a pass or fail test result is obtained every measurement pattern by the quiescent power source current test in which a plurality of measurement patterns were supplied to the integrated circuit determined to be a defective device. A state value variable in which the internal state values of all measurement patterns have been stored every net and a test result variable in which the pass or fail test result has been stored every measurement pattern are formed on the basis of those measurement patterns, internal state values, and test results. A combination of the state value variable of each net and the test result variable are compared between the nets, thereby discriminating a short-circuit failure position in the integrated circuit.
    • 在集成电路中的逻辑状态的设置被改变时,形成在集成电路的静态电源电流测试中使用的多个测量模式,在每个网络的内部状态值0/1 通过导出集成电路的仿真来提供测量图案,并且通过静态电源电流测试获得每个测量图案的通过或失败测试结果,其中多个测量图案被提供给被确定为 成为有缺陷的设备。 根据这些测量模式,内部状态形成状态值变量,其中已经存储了每个网络的所有测量图案的内部状态值以及每个测量模式存储了通过或失败测试结果的测试结果变量 值和测试结果。 在网络之间比较每个网络的状态值变量和测试结果变量的组合,从而区分集成电路中的短路故障位置。
