Description

Hardware Design Data Management Method and Storage Structure in Distributed Environment using Mixed Sharing Model.

The present invention relates to a hardware design data management method and a structure of a storage device in a distributed environment using a mixed sharing model. In particular, in the hardware design and development of a large-scale system, the association of design data design data and stable design data efficiently The present invention relates to a hardware design data management method and a storage device structure in a distributed environment using a mixed sharing model for sharing.

The design management of the formal model is done when a large number of people are required and complex design verification is required. This model is suitable for designs considering reliability through the verification of superior designers, but the reduction of design period may be reduced.

1 is a block diagram illustrating a conventional hardware design data management method, and mainly uses a design data management model called a software development methodological regular model.

Designed data in the designer's user workspace is validated and published by the project administrator, so that other designers can access the data from submit, integrate, release, and update. You need a cycle of four instructions. The functions for this command are as follows: First, the submit command means that the designer requests the version design or the design change of the design data from the upper designer, and for this purpose, the integration request (hereinafter referred to as IRs) is transmitted to the upper designer. The designer must perform a check in operation before executing the submit. Secondly, an integration command is to approve the integration to verify the design data requested by the designer to be included in the shape of the design data. However, if the validation is bad or if it conflicts with other design data, you can use the reject command to reject the integration request. Third, the release command is to ensure that design data that has been approved for integration has been validated and shaped with other designers' data by releasing IRs in the open workspace. Finally, the update command automatically updates the old version of the design data of the various workspaces of the designers within a project directory with the latest updated version of the design data.

As the design scale of hardware increases, the complexity of the design increases, and the management of hardware design data is urgently required. However, in the prior art, it is difficult to maintain and protect various versions of design data when designing a large-scale system, and it is impossible to track the situation of old design data. Also, in order to provide information related to the design management of all CAD data developed in Computer Aided Design (CAD) system, the information must be accessible online at all times. There is a problem that previous changed data values are lost.

In order to solve this problem, the conventional technique as shown in FIG. 1 has been difficult, but the method of FIG. 1 has difficulty in sharing data among multiple designers.

Accordingly, the present invention provides a method and storage of hardware design data management in a distributed environment using a mixed sharing model that can maintain and share design data among hardware design team members, improve reuse and reliability of hardware design data, and improve system development period. The purpose is to provide the structure of the device.

The hardware design data management method in a distributed environment using the mixed sharing model according to the present invention for achieving the above-mentioned object is to be shared in the workspace if the designers do not want to go through the next integration or disclosure process Connecting to access changed design data, when the designer connects to a shared workspace, the shared workspace requesting a publishing request, updating the shared workspace with the requested data, and all designers They perform an update operation when they want to see the data in the shared workspace, and if the user does not want to see the data modified in the shared workspace, they separate the workspace from the shared workspace and go through the next public process. What happens, including waiting until And a gong.

In addition, the structure of the hardware design data storage device in a distributed environment using the mixed sharing model according to the present invention for achieving the above object is composed of a plurality of workstations or machines in a distributed hardware environment that supports client / server computing A plurality of work areas connected to the plurality of workstations or machines through a communication network, having a directory information used as a shape, indicating a current version and storing link status of a current version and an old version, and the plurality of jobs It is composed of a project data repository which is statically or dynamically linked with the region and contains the file status, internal link information, version generation information, and the like.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

FIG. 2 is a block diagram illustrating a hardware design data management method according to the present invention. The hardware design environment for this is composed of several workstations or machines, and a distributed hardware environment supporting client / server computing is constructed. You must lose. Distributed hardware environments operate as network file systems (NFS) and span multiple logical disks. In addition, this hardware design environment requires that all designers' data be maintained and protected efficiently, and design management tools must be installed to enable the reuse and sharing of design data dynamically.

As shown, the mixed sharing model for hardware design data management is a hybrid design management model that has the mechanism of a regular model and is easy to dynamically switch data sharing functions to different designers. If designers do not want to modify the modified design data in the next integration or release process, they can connect to each other's shared workspace to access the changed design data. When the designer connects to the shared workspace, the shared workspace submits an IR, and the shared workspace is updated with the submitted data. All designers can use update operations when they want to see data in a shared workspace. If a user does not want to see modified data in a shared workspace, they must detach it from the shared workspace and wait until the next release process.

3 is a structural diagram of a distributed hardware design environment model to which the present invention is applied.

Typically, one logical disk is created by one file system. 3 illustrates this as a model of a distributed hardware design environment from the perspective of the user or CAD tool user.

As shown, the hardware design environment model to which the present invention is applied consists of three physical machines, disks, two logical machines, and disks. In this model, logical machines or processors, logical disks, and logical networks can be distinguished, and printers and peripherals are not considered here. A logical machine is a machine with disks mounted on a file server. A logical machine or logical disk consists of one or more machines or disks. For example, in CAD design work, logical machine M2 uses the same file system as a user of a physical machine to mount on one file server with another user, and in fact, even if the machine has physical disk D1, It is the physical disks belonging to D2 that are stored and accessed. This model can be used for storage of hardware design data or for an allocation mechanism for CAD databases to present the design data management model to be applied in the present invention.

4 is a structural diagram of a hardware design data storage device according to the present invention. In the environment as shown in FIG. 3, the library design work is performed on three physical machines and disks, but the environment of one logical machine and disk structure is the same in the network file system operation.

Defining the concept of version control and configuration management in the design and management of the library is very complicated. Directories such as ls00 / in workspace 1 and workspace 2 are used as shapes. Static references refer to links pointing to the correct file version, and dynamic references refer to ", @ current" links in the current file, that is, the storage directory. Body.1.1 and sim.1.1 in Workarea 1 indicate a static link to version 1. And version 2 of body.1.1 and sim.1.1 indicate the current version. In Workarea 2, version 3 of body.1.1 is checked out and sim.1.1 is dynamically linked. body.1.1,3 is an empty file, with a place to indicate that version 3 will be created when jan checks in.

As described above, according to the present invention, by applying a mixed sharing model for hardware design data management, reuse of hardware design data and improvement of reliability, system development time reduction, and library debugging during system integration testing are minimized. In addition, there is an effect that the hardware design data management model according to the present invention can be used for the storage mechanism of the hardware design data and the arrangement mechanism for the CAD database.
