[Industrial application field]

The present invention relates to a distributed processing system in which large-scale computers and workstations are connected via a network, and more specifically to a design data management method for centrally managing design data of a CAD system that supports the design of electronic devices, etc. on the large-scale computer side. Regarding.

[Conventional technology]

CAD systems as design support systems are being used not only for product design such as electronic equipment, mechanical products, and LSI logical design, but also for architecture and a wide range of other fields. In addition, as for the system method, in the past, a stand-alone type or a method of using a large computer on a time-sharing basis from multiple terminals was used, but the stand-alone computer type has a small processing capacity (and the time-sharing method uses a large number of computers). Because many designers are using the computer, the load on the computer is large (and this poses a problem in terms of design efficiency).For this reason, in recent years, large computers and multiple workstations have been connected to a local area network (LAN).
A distributed processing CAD system is now used in which designs that require large processing power are performed on the large computer, ie, HO3T, and other designs are performed on the workstation.

FIG. 6 shows an example of the configuration of a computer system used as a distributed processing CAD system as described above. In the figure, a large-scale computer 1 is used as the HO3T of the system, and includes TSS terminals 2a, 2, which are used in a time-sharing manner.

...is connected.

[Problem to be solved by the invention]

In a distributed processing CAD system as shown in FIG. 6, a design data management system that satisfies the following three requirements is required in order to improve the efficiency of design processing. The first requirement is) 10 S T
The goal is to centrally manage all design data on one platform. However, in order to be compatible with existing CAD systems, the storage destination file for design data can be freely specified.

The second requirement is to be able to select arbitrary design data from the WSs 4a, 4b, etc. and the terminals 2a, 2b, etc. on the HO3T1 side and process it. Here, WS4a, 4b...
- In processing, centralized data management is realized by transferring design data from the HO3T1 side and transferring the processed design data to the HO3TI side.

The third requirement is that it is possible to prevent multiple designers from updating the same design data at the same time.

However, conventionally, there is no management method that satisfies all of the above three requirements, especially the third requirement, and there is a problem that the same design data may be updated simultaneously by multiple designers. was there.

The present invention is a distributed processing CAD system that centrally manages all design data on a host, selects and processes arbitrary design data from a workstation or host terminal, and allows multiple designers to share the same design data. The purpose is to simultaneously satisfy the requirement of preventing design data from being updated simultaneously by multiple designers, and to prevent design data from being updated simultaneously by multiple designers.

Hand 0 steps 12
Controls data transfer via the large-scale computer borrowing and return processing means 11 for data registration, deletion, updating, reference, and return between the computer and the computer.

[For production]

When using the large-scale computer 5, for example, when designing using CAD, the user uses the large-scale computer internal design processing means 1.
0, the original data 8 in the original data holding means 9 is borrowed as necessary via the borrowing and returning processing means 11 in a large computer, and after the desired design is completed, the design data is transferred back to the original data holding means 9. Store. The user's purpose of using the original data is monitored by the large-scale computer borrowing and return processing means 11, and when updating the original data borrowed by the user, 1. The borrower is registered with the data location management means 7,
Other users are prevented from updating the original data at the same time. When using original data 8 for purposes other than updating,
For example, the name of the borrower is not registered in Reference H, etc.

Next, when the user designs the workstations 6a, 6b, . 't3, and after completion of the intended processing, the design data is conversely stored in the original data holding means 9. At this time, similarly to the user of the large computer 5, the name of the data borrower for the purpose of updating the original data is stored in the data storage and storage management means 7 by the large computer borrowing and return processing means 11, and the original data is simultaneously updated. is prevented.

As described above, in the present invention, design data is centrally managed in such a manner that the name of a data borrower for the purpose of data updating is stored in the data location management means 7.

〔Example〕

FIG. 2 shows the concept of design data management in the present invention.

In the figure, all design data 14 is centrally managed in a large-scale calculation IJ31 (HO3T) 5.

When a user of HO3T5 designs using CAD, design data such as C is moved to the work file 15 and C
Design is performed using the AD processing function 16. When users of workstations (WS) 6a, Gb, . . . design data, for example, A, B, .

There is a processing function 25. - Also, inside the workstation 6a, there are a borrowing/return processing function 26 that controls data transfer, a work file 27 used by the user during design, and a CAD processing function 28.

The data location management table 20 stores location information of all design data for centrally managing design data. The information [Yo, the design data name as a keyword for design data identification, the password as a keyword to indicate the access right to the data, the original file name for storing the data as an original, the purpose of updating the data. The borrower name as the identification name of the user who borrowed the data, the work location as the identification name of HO3T5 or WS6 where the design using the data will be performed, and the identification name of the task that will perform the borrowing and return processing of the data. It consists of the borrowing/returning task name, etc., and as shown in FIG. 3, there is one record 29 for each data. Here, the borrower name is also used as a keyword when returning the data after updating it.

In addition, since the contents of the data location management table 20 are shared with another borrowing and return processing task, the HO3T computer 0323
Prior to processing, the task number of the self-task given from is sent to the borrowing/returning task name through the route shown in Figure 3 - ■, and other tasks do not access the data if the task name is set. Exclusive control is performed at However, even if a task name is set, if it is confirmed that the task with that number is not running at 0323, then the next accessed WS may use that data, for example.

The borrowing/returning processing functions 22 and 26 transfer design data and manage their location in response to requests from the CAD processing functions 25 and 28, respectively. However, the borrowing and returning processing function 26 in the WS6a, . . . operates in cooperation with the borrowing and returning processing function 22 in the HOSTS. First, in response to a data registration request, the design data in the work file 24° 27 is transferred to the original file 21 using the design data name, password, original file name, and work file name as parameters.
and transfer its location information to the data location management table 20.

It is determined whether the request is from T5 or WS6a, . . . . If the request is from the WS6a, . After this is passed, the process moves to step 33. If the request is from the HOST side, the process in step 32 is not performed and the HO
The content of the management request is analyzed by the rendering return processing function 22 on the 3T side.

When a data registration request is made, a new empty area is secured in the data location management table 20 in step 34, and the above-mentioned parameters and the task name given from 0323 are stored therein in step 35. Next, in step 36, data is copied from the work file to the original file 21 according to the specified design data name, work file name, and original file name. Here, in response to a request within the HO3TS, as shown in ■→■ in FIG. 3, the request is sent to the WS6a.

In response to a request from the . When the data copying is completed, the task name in the location management table 20 is cleared as a termination process in step 37, and the CA that sent the data registration request is
The D processing function is notified of the end of processing, and all processing ends.

When requesting deletion, in step 38, as shown in ■ in Figure 3,
The task name is entered as the corresponding data management information in the data location management table 20, the corresponding data in the original file 21 is deleted in step 39, the management information in the data location management table 20 is also deleted in step 40,
All processing ends with the end processing in step 37.

When requesting data update, step 4 is shown as ■ in Figure 3.
In step 1, the above-mentioned parameters and task name are set as management information in the data location management table 20, and in step 4
In step 2, the designated design data is copied from the original file 21 to the work file. In response to a request from within the HOSTS, copying is performed through the route ``■-■'' in FIG. 3, and in response to a request from the WS 6a, . . . After the data copying is completed, the process goes through step 37 and ends.

The operational flow when a reference is required is basically the same as when an update request is made, with the only difference being that in step 41, among the parameters, the borrowed pitch name and work location are not entered in the data location management table 20.

At the time of a return request, the task name given from 0823 is set in the corresponding data management information in the data location management table 20 in step 43, as shown by ■ in FIG. Next, in step 44, it is determined whether the borrowed pitch name in the parameters matches the time of borrowing for updating, and if they do not match, the process is interrupted. If they match, step 45
The specified design data is copied from the work file to the original file 21. Copying is performed through the path ■-■ in Figure 3 for requests within I (OS T5, and ■-■'-■ for requests from WS6a, etc.).After data copying is complete. All processing ends after step 37.
