The search result displays the relationship between the control CPU, controller, and functional device in a hierarchical structure.

In step 3, component information of the specified function is extracted from the resource DB 1 based on the keywords: product group, model name, function name, and performance / method on the work screen shown in FIG. The copied information (parts information, circuit structure, resource source information, function information, performance / method, etc.) is copied to the temporary parts table. Here, the search result also displays the relationship between the control CPU, controller, and functional device in a hierarchical structure.
Optimal part information can be searched according to the level.

Edit the temporary parts table, such as searching for parts, searching for similar parts, searching for new parts, searching for new parts from functions, replacing parts, deleting parts, and changing the circuit structure.

In this way, the search result can be copied to the new parts table via the temporary parts table with the hierarchical structure data of the control CPU, controller, and functional device added. Since this new parts list is displayed in a hierarchical structure of the control CPU, controller, and functional devices,
The user can edit while checking the hierarchical structure.

In step 7, based on the temporary parts table, editing of the detailed parts table and editing of the circuit diagram are performed for each circuit block at three levels of the control CPU, controller, and functional device. In step 8, the parts table is divided in consideration of the PCB, and in step 9, the structure information of the parts table is deleted and converted to a normal parts table. At this stage, information such as the hierarchical structure is lost.

In this manner, component configuration information of an electronic circuit board having a new function is created and edited based on component configuration information of an electronic circuit board manufactured in the past, and the data is stored in the storage unit 6.
