Title: Integrated circuit tester
Inventor: AOYAMA SHINTARO
IPC: G01R31/28
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress attenuation in the voltage amplitude of a test signal while eliminating the unapplicable time of test signal by providing a second transmission line having a transmission delay time equal to or shorter than one half of the I/O switching time at an I/O terminal to be tested and receiving an output signal from the I/O terminal through that line. SOLUTION: In order to connected an I/O terminal 4 to be tested with the input terminal of a comparator circuit 2, a second transmission line 6 having a constant characteristic impedance is provided independently from a first transmission 5. The circuit 2 is arranged in the vicinity of the terminal 4 while connecting the input terminal with a terminal voltage source 7. Consequently, the length of the transmission line 6 can be shortened and the delay time is shortened to one half or less of the I/O switching time at the I/O terminal and thereby confliction of I/O signals is avoided at the terminal 4 even if a transmission delay time is present between the transmission lines 5, 6.  Since the terminal voltage source 7 is in high impedance state during the interval when a test signal is applied, a test signal from a driver circuit 1 is applied to the terminal without attenuating the amplitude.

Title: Signal disconnection circuit
Inventor: MOTOI HIDESUKE
IPC: H03G3/34
Filed: 1985-04-27
Abstract: PURPOSE:To eliminate malfunction of a signal disconnection circuit when a signal input level is small by providing a switching transistor (TR) bridging a resistor being a part of a voltage divider in response to an output value of an active load of a differential amplifier and a switching TR sending an interruption signal through the ON/OFF state of the former TR. CONSTITUTION:TRs 3, 4 of the differential amplifier are subject to ON/OFF control by a signal voltage whose level is to be supervised, when the TR 3 is turned off, the TR 4 is turned on and the ON-voltage is applied from the active load of the differential amplifier to a TR 7 to turn off a TR 8 thereby outputting a high level voltage from the circuit. When the TR 3 is turned on and the TR 4 is turned off, the TR 8 is turned on and the circuit outputs a low level voltage. In this case, since the input voltage of the TR 4 interrupting the signal disconnection circuit and the voltage after being switched into the interrupting state are changed by turning on and off the TR 7, there is a difference in the input current of the TR 3 required for inversion and the TR 3 is not restored without a higher input level than the input signal level at signal disconnection, then a hysteresis is provided to the restoration of disconnection to stabilize the operation of the signal interruption circuit.

Abstract: PURPOSE:To simplify the input of data by performing the simulation of a carrier request based on a normal random number as long as the ratio between the standard deviation of the generating intervals of carrier requests and the average value is kept constant in a certain system. CONSTITUTION:A simulation device which produces a carrier request based on a normal distribution consists of a mini-computer 1, a keyboard 2, a display 3, a floppy disk device 4, and a printer 5. The simulation of the carrier request is carried out with the input of an average carrier request interval (mij) and the input of a confusion degree variable (a) set properly by the experience. At the same time, the repetition control variables (i) and (j) are set for generation of a normal random number and a carrier request generating interval (xij) is calculated and recorded. Then the integrated value of said generating intervals is calculated and compared with the estimated simulation time. Thus the carrier simulation is carried out at the estimated simulation time point with the arrangement of said recorded interval (xij) defined as the due interval. In this case, the variable (a) is equal to the ratio between the standard deviation of each carrier request and the average value.
