Problems solved by technology

[0004] However, since the CAD devices disclosed in Japanese Patent Application Laid-Open Nos. H9-101982 and 2004-46396 enable designers to edit graphic data by simply dividing the graphic data into a plurality of layers, there is such a possibility, That is, the designer's operation to edit graphic data may become complicated and reduce work efficiency
[0005] In addition, the purpose of each layer cannot be quantitatively defined, resulting in different ways for different designers to use layers
Potential for problems if third parties modify graph data, or if graph data is used in downstream operations

Embodiment Construction

[0044] Exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. In the following embodiments, the present invention is described by taking a CAD device for an electronic system as an example, however, the present invention is also effective for CAD devices for various applications other than the CAD device for an electronic system.

[0045] Graphic data used in a CAD device according to an embodiment includes a plurality of layers as shown in FIG. 1 . Specifically, the graphic data includes: a layer including a circuit diagram, which is fundamental to a drawing of an electronic system; a layer including various annotations related to the circuit diagram; a layer including various constraints for designing the circuit diagram ; a layer including a result of a design rule check (DRC); a layer including an analysis result obtained by a simulator; a layer including information related to a part specific...

Abstract

A CAD apparatus includes a layer displaying unit and an editing unit. The layer displaying unit displays elements included in each of layers that form graphic data onto a display unit in a superposed manner. The editing unit creates a data structure of associating between elements displayed on the display unit. If an element to be deleted is provided with a data structure of associating elements with each other, the editing unit also deletes another element associated via the data structure.

Description

technical field [0001] The present invention relates generally to techniques for computer aided design (CAD). In particular, the invention relates to editing of graphic data comprising a plurality of layers. Background technique [0002] CAD devices have been widely used to improve the efficiency of design work. Furthermore, the graphic data generated with the CAD device is used in downstream operations, for example, in the manufacturing process, thereby further improving efficiency. In CAD, a drawing is sometimes created by splitting it into layers. [0003] For example, Japanese Patent Application Laid-Open No. H9-101982 discloses a technique of dividing a picture into layers including common parts and layers including non-common parts. On the other hand, Japanese Patent Application Laid-Open No. 2004-46396 discloses a technical idea that facilitates maintenance of graphic data by inputting drawing frame information, building frame information, parts information, and si...
