摘要： An interposer to be mounted with an integrated circuit to be a test object is provided with a switch and a probe to detect an electric current corresponding to individual terminals of the integrated circuit. A test pattern signal is then inputted to the integrated circuit through a test substrate as a switch that is connected to a power supply terminal of the integrated circuit and that is turned off. If the integrated circuit normally operates and the current values of all the terminals of the integrated circuit are within a tolerance, the power supply terminal connected to the turned-off switch is identified as a terminal that may be removed.

摘要： An output buffer includes inverters, a delay circuit for delaying an input signal, buffers and switches. The output buffer transmits a logic signal to a transmission path and, in accordance with an amount of signal attenuation in the transmission path, creates a waveform including four or more kinds of signal voltages. The buffers are redundantly connected in parallel, and the number of buffers concurrently turn ON is controlled by respective switches provided in series with output resistors of the buffers. By selecting the buffers of switches which are turned ON, the preemphasis amount and a number of preemphasis taps are adjusted through a selector logic selection signal so that the preemphasis amount is made variable and the ON resistance of the buffers is made constant.
