  • Publication number: 20070283302
    Abstract: In an LSI analysis apparatus, a logic element pair extracting unit extracts an unselected logic element pair when an input unit receives circuit description input. A searching unit searches for an input pattern causing the extracted pair to perform concurrent transition. When an input pattern causing concurrent transition is found, the searching unit determines the extracted pair to be a pair capable of concurrent transition (concurrent transition pair), and holds the input pattern causing concurrent transition. When an input pattern causing concurrent transition is not found, the searching unit determines the extracted pair to be a non-concurrent transition pair. An input pattern operation ratio calculating unit calculates an input pattern operation ratio for each input pattern causing concurrent transition. A detecting unit detects an input pattern yielding the highest input pattern operation ratio. An output unit puts out the detected input pattern, non-concurrent transition pairs, etc.

  • Patent number: 7299437
    Abstract: A selector selects an FF pair (FFs, FFe) in circuit information, a calculator calculates value-capturing condition data at FFe, a divider divides a path set that matches the value-capturing condition data from a set of paths between the FF pair (FFs, FFe), and a multi-cycle path detector determines whether all the paths in the path set are multi-cycle paths. When the path set is a multi-cycle path, it is added to a timing exception path list that is output by an output unit.

  • Publication number: 20070220457
    Abstract: An apparatus for creating a simplified false-path description on a false path among paths in a target circuit extracts, from descriptions on the paths, a target path description on a target path. The apparatus judges whether the target path is a false path based on the target path description. The apparatus identifies, when it is judged that the target path is a false path, a sufficient set of elements from elements included in the target path. The settings for causing every element in the sufficient set to transmit a signal conflict. The apparatus creates the simplified false-path description on the false path by deleting, from the target path description, a description on elements that are not included in the sufficient set.

    Abstract: A polyarylene sulfide resin which has an index of coupling reactivity at 320° C. of 2.0 or lower and an amount of SO2 generated therefrom at 300° C. of 0.02 mg/g or smaller; and a process for producing the polyarylene sulfide resin, which comprises polymerizing a polyfunctional halogenated aromatic compound with lithium sulfide in an aprotic organic solvent, and then washing the resultant polymer in a molten state. A composition comprising the polyarylene sulfide resin obtained by such process and an inorganic filler is reduced in unevenness of fluidity between lots and is reduced in sulfur odor emission during molding.

  • Publication number: 20050120271
    Abstract: A false path detection program whereby passing points of signal lines constituting false paths are directly detected, thereby shortening the processing time necessary for the false path detection and the processing time of tools utilizing false path information. A storing section stores, in a storage device, circuit information about a circuit designed by a designer. A signal value generating section generates an impossible signal value with respect to a signal line in the circuit. A signal propagation inspecting section assigns the signal value generated by the signal value generating section to an input of a gate connected to the signal line with respect to which the signal value has been generated, and examines whether signal is propagated through the other input of the gate only when accompanied by the signal value. If signal is propagated through the other input of the gate, a passing point acquiring section acquires a passing point of the other signal line connected to the other input of the gate.

  • Patent number: 6758232
    Abstract: A steam conditioning system including a steam conditioning valve 1 for depressurizing and desuperheating steam S by supplying moisture W in the conditioning valve. A discharge pipe 3 connected to the steam conditioning valve 1 has a horizontal section 3a, and the horizontal arrangement section 3a is provided with a moisture drain 4 or at a portion near the bottom. Condensed moisture W1 is extracted from this moisture drain 4 and is recycled as moisture W to be supplied to the steam S in the conditioning valve 1. The steam conditioning valve 1 further has a reduced annular section 9 with a nozzle 5a disposed therein for injecting subcooled water mist W. A transport conduit 5 connects the drain 4 to nozzle 5a. Moisture W is drawn into steam flow S due to the Venturi effect caused by the pressure drop through the reduced annular section 9.
