[Problem to be solved by the invention]

In the conventional technology described above, when data is created using a CAD system, the CAD system is determined in consideration of the scale of the data. Therefore, when creating large-scale data, a CAD system of an appropriate scale is required.

However, the larger the scale of the CAD system, the more expensive it becomes, and introducing a large-scale CAD system imposes a considerable economic burden.

The present invention has been made to solve the above problems.

The purpose of the present invention is to convert large-scale data into inexpensive and small-scale CA
The purpose of this invention is to provide a pig processing method created by using D.

[Means to solve the problem]

In order to achieve the above objective, in a data processing system that creates data using a CAD system, a large-scale data unit is divided into units that can be processed by a small-scale CAD system, and the data for each divided unit is Said small scale C
The data is created in the AD system, the created data is input to a host computer, and the host computer integrates the data to create large-scale data. In addition, the small-scale CA
The data created by the D system is registered in the library of the host computer.

[For production]

Divide a large data unit into units that can be handled by a small-scale CAD system, create data for each divided unit on the small-scale CAD system, input the created data into the host computer, and then The input data is integrated to create large-scale data units.

〔Example〕

Hereinafter, one embodiment of the present invention will be specifically described using the drawings.

FIG. 1 shows a large-scale multilayer substrate on which mask pattern data is to be created using the data processing method of the present invention. This board consists of two layers, 101.degree. A layer and 8 layers 102. Reference numerals 103 to 106 indicate portions where wiring patterns for components mounted on this board are present. 107 is”
2 shows a portion where the wiring pattern does not exist. Furthermore, this substrate is too large to be handled by the CAD system used in the embodiments of the present invention.

FIG. 2 is a diagram in which the substrate shown in FIG. 1 is divided into sizes that can be handled because it cannot be handled by the CAD system used in the embodiment of the present invention.

This division is performed by dividing the board into parts with wiring patterns for components mounted on the board and parts without them, and into parts by layer. Each of the divided parts has a size that can be handled by the CAD system used in the embodiment of the present invention.

Reference numerals 203 to 210 indicate portions with wiring patterns for components mounted on the board, and reference numerals 201 and 202 indicate other portions. Also 201.203°205, 207.20
9 is the A layer part, 202.204.206.208°21
0 indicates the B1 portion. Components 201 to 210 constitute a large-scale multilayer board, and are referred to as components 1 to 10, respectively. In addition, the mounting positions indicating where these components are placed on the large-scale multilayer board are shown as location 1 for component 1.2, location 3 for components 3 and 4, and location 3 for components 5 and 6.
is located at location 5, parts 7.8 are located at location 7, and parts 9 and 10 are located at location 9.

Figure 3 shows how mask pattern data for parts machining to 10 parts divided as shown in Figure 2 is processed using a small-scale CAD system (PC computer).
This figure shows a system configuration for creating mask pattern data for a large-scale multilayer board by integrating the created data with a host computer (AD, etc.). 301
is a small-scale CAD system, such as a personal computer CAD. 302 is a library for storing mask pattern data of divided parts created with the old small-scale CAD system 3, and 303 is a file storing information for integrating the data created by dividing. . 30
4 is a program that performs integration processing, and 305 is a file that stores integrated data.

In FIG. 3, mask pattern data for parts divided as shown in FIG. 2 is created using a personal computer CAD 301, and each created data is stored in a library 302. Storage can be done via media such as floppy disks, or online if the personal computer is connected to a host computer. As shown in FIG. 4, the library 302 stores mask pattern data' corresponding to the name of each component. On the other hand, information for integrating the divided parts is stored in the file 303, as shown in FIG. 5, so that the correspondence between eyebrows, mounting positions, and names of parts can be seen. For example, the first line in FIG. 5 indicates that component 1 is mounted at location 1 and is mask pattern data for layer A. In the integration process 304, the integration information of the file 303 is referred to and based on this.

The data of each part in the library 302 is merged taking into account the layer and mounting position, and is output to a file 305.

In this way, mask pattern data for a large-scale multilayer substrate is created.

Note that by storing various pieces of divided and created data in the library 302, it is possible to synthesize various combinations of large-scale mask pattern data by changing only the information for integration in the file 303.

〔Effect of the invention〕

As explained above, according to the present invention, the personal computer CA
By dividing large-scale data that cannot be handled by D into sizes that can be handled by PC CAD, creating the divided data with PC CAD, and integrating the created data with the host computer, it is possible to Scale data can be created, saving labor in design.
It is economically effective. Further, by using a plurality of inexpensive personal computer CADs and creating divided data in parallel, it is possible to shorten the data creation period.
