2. Description of the Related Art In general, when designing and manufacturing a printed circuit board on which an electric circuit is mounted, an electric circuit designer first needs a CAD (Computer Aided Design).
n: Computer-aided design) system is used to design an electric circuit and issue a parts list, and the printed board designer also designs the printed board based on the electric circuit. And when designing an electric circuit,
For the selection of various electric and electronic parts used in electric circuits,
A desired component can be selected by searching a component information system prepared separately from the CAD system. When designing a printed board, the pattern of the component is registered from the component library registered in the CAD system. Graphic information such as shape can be selected and used for printed circuit board design. In addition, the component information relating to various electric / electronic components registered in the component information system described above is configured so that it can be used even when a bill of materials is issued, and the desired component is not registered in the component information system. in case of,
The component information of the component to be newly adopted can be newly registered in the component information system by newly assigning a component code capable of uniquely identifying the component.

As an example of a system for managing parts information, the "parts information management system and parts information management method" described in Japanese Patent Laid-Open No. 5-135066 is known.

This publication describes a technique for synthesizing component information and design information, centrally managing them in a component information storage unit, and creating a parts table from the component information stored in the component information storage unit. There is.

Also, as an example of a system for creating and managing a parts library, a "CAD library registration system" described in Japanese Patent Laid-Open No. 10-293774 is known.

This publication describes a technique for automatically creating a CAD library relating to circuit symbol information from document information such as a catalog of electronic parts and registering it in a CAD device.

[0007]

In the above-mentioned conventional design work for electric circuits and printed boards, the component information registered in the component information system and the component library registered in the CAD system are indispensable. This is a situation, and therefore, when newly adopting a part that has not been registered in each system, it is indispensable to newly register this new part in each system.

However, in the conventional method of registering a new part, the registration of the part code and the part information in the part information system and the registration of the part library in the CAD system are not always synchronized in time. Therefore, it had the following problems.

First of all, in order to first create a circuit diagram in a design work, usually a registration application of a parts library to a CAD system is first made, and a parts table is issued when the circuit diagram is completed. Since the application for registration of the component code and component information to the component information system is performed, there may be a difference in the component code and the product name code between each system, causing confusion to the designer and the same component library. There is a possibility that registration will be duplicated despite the parts.

Second, since the application for new registration of the parts code and the parts information is made just before the issuance of the parts table after the circuit diagram design is completed, even if the applied parts are inconvenient, the deadline can be delivered. In some cases, the change to the alternative parts may not be in time, leading to a product defect.

Further, since the application for the registration of the new part is made by using the paper application form, a long lead time is required between the plurality of departments for processing the registration application, and the application documents are distributed to the plurality of departments. However, there is a problem that a large amount of paper copy is required.

Further, since the designer uses a paper-based catalog or specifications to search for newly used parts, there is a problem in that much searching time is required.

The present invention has been made in order to improve the above-mentioned circumstances, and an object of the present invention is to newly adopt electric and electronic parts necessary for designing an electric circuit and its printed board. In this case, a step of registering component information such as electric characteristics of the electric / electronic component in the component information system, and a step of registering a component library including symbols on a circuit diagram of the electric / electronic component in the CAD system, By executing them synchronously in time, it is possible to eliminate the discrepancy between the parts used in the electrical circuit design and the printed circuit board design, and to digitize the workflow of design work such as approval of design contents and drawing request. It is to provide a newly adopted parts registration system that can be managed by the system.
