摘要： Apparatus for testing integrated circuits containing a controller or other sequential circuit at actual operating speed while minimizing the length of the test sequence and achieving high fault coverage are provided. The states of a state register are assumed controllable and observable, and a set of test patterns is obtained for a combinational circuit not containing said state register. An invalid-state generation logic circuit is added for generating invalid states, which are states contained in the generated test patterns but cannot be set by a normal transition from the reset state. A multiplexer is added for selecting the output of a next-state generation logic circuit or the invalid-state generation logic circuit for input to the state register based on a state transition mode selection signal. Signals corresponding to pseudo-primary outputs during test generation are made observable, and the multiplexer output signal is externally detectable as a state output signal.

摘要： The invention provides a method of design for testability at RTL which can guarantee high fault coverage and a method of test sequence generation for easily generating test sequences for an RTL circuit which is designed to be easily testable by the method of design for testability. In the RTL circuit, scannable registers are selected so that the RTL circuit can attain an easily testable circuit structure such as an acyclic structure. This RTL circuit is timeframe expanded on the basis of a predetermined evaluation function and logically synthesized, so as to generate a timeframe expanded combinational circuit, that is, a gate level timeframe expanded circuit, as a circuit for test sequence generation. For the timeframe expanded combinational circuit, test patterns for multiple stuck-at faults are generated, the test patterns are transformed into test sequences on the basis of data on timeframes including primary inputs and pseudo-primary inputs, and the test sequences are transformed into scanning test sequences in view of a scan shift operation.

摘要： A state control portion causes a sense amplifier portion to be at an active state and for causing the sense amplifier to be at an inactive state. A feedback portion causes the control device to causing the sense amplifier portion to be in the inactive state when a path is formed between a power source and a ground in the sense amplifier. A latch portion holds an output of the sense amplifier output when the path is formed. The state control portion comprises a first transistor acting as a switching device. The feedback portion produces a control signal using an output of the sense amplifier portion and a clock signal obtained from a detection circuit, and supplies the control signal to the first transistor. A second transistor for precharging is connected between the first transistor and the power source.

摘要： A spin-valve read head of the giant magnetoresistive type in a data storage system has at least one magnetic thin film layer comprising a plurality of magnetic thinner film layers of ferromagnetic material with the same crystal plane orientation from one magnetic thinner film to another, and an interface between adjacent magnetic thinner films having a discontinuity in single-crystal epitaxial growth. Each magnetic thinner film layer is composed of an alloy including each of Fe, Ni and Co and has a weight ratio of Co:Fe equal to 90:10. The crystal has a crystal structure that is face centered cubic and a crystal plane orientation (111) that is highly ordered. The interfaces may be layers of Ni or Cu. The layers all exhibit a condition of magnetic orientation and annealed structure resulting from being annealed and cooled in a magnetic field sufficiently to have an anisotropic energy of the first magnetic thin film layer in an equilibrium state that is smaller than an identical structure before annealing.
