A design data merging apparatus includes a merging determining unit that determines, for a plurality of design data of which each has product name information and has a same identifier for uniquely identifying a product, whether the product name information given to the plurality of design data are the same, and a merged data creating unit that merges the plurality of design data when it is determined by the merging determining unit that the product name information given to the plurality of design data are the same, and creates merged data obtained by merging a plurality of design data.
摘要:
The time and trouble of a mismatch cause analysis after logical equivalence verification can be reduced, and design and verification TAT can be shortened. A logical equivalence verifying device performs logical equivalence verification between two circuits, and displays the result of the logical equivalence verification. A preprocessing section 7 performs structural matching so as to determine whether there are portions corresponding in circuit structure to each other in corresponding logic cones of the two circuits. An internal DB 5 records the results of the structural matching as an identifier for each element. A subcone extracting section 8 extracts, as a subcone, a collection of elements, which are mutually to one another and have the same identifier, from each logic cone. A verifying section 9 performs logical equivalence verification between the two circuits for each of the extracted subcones. A display control section 10 displays only those subcones for which the logical equivalence verification has resulted in mismatch.
摘要:
A circuit designing apparatus of an interactive type which enables a simplified and high-speed circuit design process while largely reducing a burden on a designer, having a speed analyzing unit for conducting a delay computation for each wiring path on a circuit to be designed and a display control unit for displaying a result of the delay computation by the speed analyzing unit on a display unit. When the speed analyzing unit conducts a delay computation, a delay value of each logic component forming the circuit that is an object of the design is set and altered according to a dullness of a signal waveform inputted to the logic component. The circuit designing apparatus of an interactive type may be applied to a system for conducting a circuit design of an integrated circuit such as an LSI or the like or a printed circuit board.

A circuit diagram display apparatus displays a plurality of logic circuit diagrams. An associating unit associates the logic circuits based on at least any one of identification information, structural information, logical equivalence information, and external designated information about the logic circuits. A display format changing unit changes a display format between a side-by-side format and one-below-the-other format. A display controller performs control to display a target point in the logic circuit diagram in the same position before and after the display format is changed.

The disclosed method includes: generating data of a first circuit diagram by disposing a block that represents a connection relationship between first branch lines included in a first bus line in a second circuit diagram and second branch lines included in a second bus line to be connected to the first bus line in the second circuit diagram so as to connect the first bus line with the second bus line through the block, wherein the block represents that the connection relationship identified by connection relationship data is depicted in detail in a lower-layer than a layer of the block; and generating display data including the connection relationship data and the first circuit diagram to output the generated display data.
摘要:
The configuration data obtaining unit obtains a network configuration data, and the actual-apparatus collection result data obtaining unit obtains an actual-apparatus collection result data. Then, the comparing unit compares a network address in the network configuration data corresponding to a network apparatus with a network address in the actual-apparatus collection result data corresponding to the network apparatus, and determines whether the network address is normally set to the network apparatus based on the comparison result.

A system aiding for design includes a determining unit determining whether it is possible to first product data with second product data by comparing interface data of the first product data with interface data of the second product data and a replacing unit replacing the first product data contained in design data with the second product data when the determining unit determines that replacement is possible.
