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.

Design data merging apparatus and design data merging method

A CAD apparatus, a CAD method and a computer-readable recording medium storing a CAD program, configured to display and edit graphic data including a plurality of layers, and to display information about a layer to which the element belongs, so that a user can easily find for what use the element belongs to the layer in use, thereby being able to perform required editing work immediately.

A property of connection relationship information for identifying an internal/external connection of each point is registered in a part DB. When the part is one basic part representing a standard configuration article, an anchor ID is registered in the part DBor a product DB. Part group extracting unitextracts parts constituting a system from a design drawing generated by drawing generating unitand a group of parts connected at the connection point for each basic part assigned with the anchor ID. For each extracted part group, work instruction document generating unitdetects a standard configuration article having a basic part assigned with the same anchor ID as that of the basic part included in the part group, from the product DB, extracts a difference in part configuration between the part group in the system design drawing and the detected standard configuration article, generates information indicating the extracted difference as the work instruction document for each part group, and outputs the work instruction document.

Work instruction sheet preparing device, method and program

A device includes, a search controlling information storing unit that stores, for each searching purpose, the search controlling information indicating whether or not the search is to be proceeded for the kinds of parts between the interfaces in the parts is defined and registered, a set information collecting unit that decides the interface of the parts to be searched, according to the search controlling information for each search object, from both the design information of the system constitution diagram and the registered information of the library database of the parts and the interfaces, and traces the connection relations of the interfaces thereby to collect the set information of the searched parts and the interfaces from the library database of the design information of the system constitution diagram, the parts and so on.

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 sectionperforms 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 DBrecords the results of the structural matching as an identifier for each element. A subcone extracting sectionextracts, as a subcone, a collection of elements, which are mutually to one another and have the same identifier, from each logic cone. A verifying sectionperforms logical equivalence verification between the two circuits for each of the extracted subcones. A display control sectiondisplays only those subcones for which the logical equivalence verification has resulted in mismatch.

In a CAD system, an electronic system is arranged by receiving an aid of a computer, and also a designing work of an architecture of this electronic system is carried out under the aid of the computer. An estimation with a high usability can be realized in high precision in an upstream stage, namely an earlier designating stage. The acquired design information is stored as know-how, and this stored know-how can be succeeded to the design information in a downstream stage. In this CAD system, a block diagram is edited by a block diagram input/editing unit, and this block diagram contains symbols indicative of independent functions, and lines used to connect these symbols. These symbols and lines are represented as the same design information. Both design information and parameter information may be applied to the symbols and the lines in a similar manner. Furthermore, the respective design information owns such a structure having a plurality of detailed level information with an architecture idea of a layer. The estimation parameter information to be applied to the symbols and the lines is prepared as templates in a parameter template holding unit. As a result, this template may prompt a user to input the necessary information.

System design/evaluation CAD system and program storage medium

A graphic editor for performing various editing processes such as inputting, moving, copying, and deleting a graphic pattern and a line on a display screen in a graphic editing system such as a CAD, etc. The graphic editor realizes a user interface for simultaneously selecting an object to be processed and a function, thus improving the efficiency of the editing operation. The editor comprises an area specifier for specifying an area as a rectangle having a diagonal whose start and end points are specified by the area specifier, and a graphic operating unit for determining the existence of a symbol or a line in a specified area to give a predetermined process on the symbol or the line. The predetermined processes can be identified by determining whether or not a symbol and/or a whole or a part of a line exists in or crosses a specified area.
