A test pattern sequence which is used to test a delay fault or an open fault which accompanies a delay occurring in an IC is easily and rapidly generated. A list of locations such as logic gates and signal lines within the circuit where a fault is likely to occur is prepared (101). One of the faults is selected, and an initialization test pattern v1 which establishes an initial value for activating the fault at the location of a fault is determined by the implication operation (103), and a propagation test pattern v2 which causes a stuck-at fault to be propagated to a following gate is determined by the implication operation (105). A sequence formed by v1 and v2 is registered with a test pattern list (107), and the described operations are repeated until there remains no unprocessed fault in the fault list.

There is provided a small-type semiconductor integrated circuit whose circuit area is small and whose wiring length is short. The semiconductor integrated circuit is constructed in a multi-layer structure and is provided with a first semiconductor layer, a first semiconductor layer transistor formed in the first semiconductor layer, a wiring layer which is deposited on the first semiconductor layer and in which metal wires are formed, a second semiconductor layer deposited on the wiring layer and a second semiconductor layer transistor formed in the second semiconductor layer. It is noted that insulation of a gate insulating film of the first semiconductor layer transistor is almost equal with that of a gate insulating film of the second semiconductor layer transistor and the gate insulating film of the second semiconductor layer transistor is formed by means of radical oxidation or radical nitridation.

The testing device includes: a deterministic jitter application unit for applying deterministic jitter to a given input signal without causing an amplitude modulation component and supplying the input signal with the deterministic jitter to the electronic device; a jitter amount controller for controlling the magnitude of the deterministic jitter generated by the deterministic jitter application unit; and a determination unit for determining whether or not the electronic device is defective based on an output signal output from the electronic device in accordance with the input signal.
摘要:
In a rotary pump for a braking apparatus, a discharge trench is formed on an axial direction end surface of a second side plate that forms a mechanical seal. As a result, rotors are pressed back toward a side of a first side plate by a discharge pressure of brake fluid channeled to the discharge trench. Accordingly, a force pressing the rotors toward the second side plate is reduced and frictional resistance is reduced.

A fault analysis method and apparatus which is able to improve the reliability of fault analysis of semiconductor integrated circuit. In case of supplying a test pattern sequence having a plurality of test patterns to the semiconductor IC, an analysis point whose electric potential changes according to the change of supplied test pattern is placed corresponding to the test pattern sequence. Then, a transient power supply current generated on the semiconductor IC according to the change of the test pattern is measured and determined whether the measured transient power supply current is abnormal or not. A defection point is presumed based on the test pattern sequence where the transient power supply current is abnormal, and the analysis point placed corresponding to the test pattern sequence.

A signal under measurement is transformed into a complex analytic signal using Hilbert transformation to estimate an instantaneous phase of the signal under measurement from the complex analytic signal. A least mean square line of the instantaneous phase is calculated to obtain a linear instantaneous phase of the signal under measurement, and a zero-crossing timing of the signal under measurement is estimated using an interpolation method. Then a difference between the instantaneous phase and the linear instantaneous phase at the zero-crossing timing is calculated to estimate a timing jitter sequence. A jitter of the signal under measurement is obtained from the jitter sequence.
