    摘要: Logic emulation according to the present invention is aimed at an object to provide a logic dividing and module wiring system for operating logic related to external interface signals and interface signals among circuits obtained as a result of division or a logic circuit at a high speed. In a logic emulation system, information on assignments of external interface signals of logic to connector pins is read in during division of the logic. Logic related to an external interface signal assigned to a connector pin is assigned to a field programmable gate array directly connected to the connector pin. In addition, delays are checked after the division of a logic circuit in order to determine the level of delay criticality of each interface signal between field programmable gate arrays. Wiring of a module is then carried out in accordance with the levels of criticality.

    摘要: A program data creating method and apparatus for use with programmable devices in a logic emulation system provides high-speed logic emulation of an LSI for logic and function verification. The logic data defining the logic circuits of the LSI is divided into a plurality of unit blocks in a layout analogous to the floor plan represented by floor plan information for the LSI. The unit blocks are allocated to the programmable devices automatically. The names of the signals defined within the design data regarding the LSI are made to correspond with the names of the signals in effect when the design data is deployed within the programmable devices, after optimization of the logic. This allows the program data for the programmable devices to be created and corrected using the signal names as set forth in the design data.

    摘要: A design support system for executing logic verification so as to perform work management, progress state management and logic quality management efficiently in a logic verification process and so as to improve the man-hour for development and the throughput of computer resources. For every verification item to be executed, management information including a verification item number for identifying a verification item, confirmation information for indicating the fact that no failure has been confirmed in the verification item, a prerequisite verification item number for identifying another verification item required to be confirmed as a prerequisite for the verification item is stored in a memory of the system. Before execution of logic simulation which is performed by giving test data for logic verification of the design data to the design data as a subject of logic verification, data in the memory are searched so that logic simulation is executed in the case where all verification items as prerequisites for verification items to be executed have been already confirmed.

    摘要: A portable trimmer has a supporting tube extending straight forward from an engine at its rearward end to a cutting device at a forward end. A handle-bar is mounted on a middle portion of the supporting tube at an intersecting point. First and second grips extend upwardly from two corresponding ends of the handle-bar. The handle-bar has a first portion extending from an intersecting point to the first grip, and a second portion extending from the intersecting point to the second grip. The first portion extends across a width of an operator's body, and is bent in a rearward direction. The supporting tube has an inclination with respect to a phantom line connecting the first and second grips such that said cutting device is located in front of a center of the operator's body when the operator holds the grips in a natural posture. This portable trimmer increases the area in which weeds can be cut in a single movement, and provides for easy handling.

    摘要: The electronic circuits of a large-scale ASIC or logic device are assigned to a plurality of programmable chips with logic block division that enables the finished circuits to operate at appropriate timings. A logic division processing unit divides the electronic circuits into a plurality of groups for automatic assignment to a plurality of programmable chips. A checking unit determines whether the designated logic blocks are accommodated in one programmable chip, and a division processing unit determines which logic blocks are to be assigned and the order of assignment priorities when the designated logic blocks are not all accommodated in the same programmable chip.
