Abstract:
A LSI tester comprising:a plurality of tester pins each connected to an input/output pin of a semiconductor integrated circuit; a plurality of dc test devices each applying one of a predetermined voltage and a predetermined current to a corresponding one of said plurality of tester pins so as to determine a dc characteristic of the semiconductor integrated circuit; a function test device for determining a function of the semiconductor integrated circuit by applying a voltage corresponding to a function test pattern to selected ones of said plurality of tester pins and receiving, via the selected ones of said plurality of tester pins, corresponding logic values returned from the semiconductor integrated circuit as a result of the application of the voltage; and connecting means for connecting, in the dc test, said plurality of dc test devices to said plurality of tester pins, respectively, and connecting, in the function test, said function test device to the selected ones of said plurality of tester pins.
