In this case, if there is an error in the information of the object part group in the lower layer of the source, and the error is corrected, a similar modification must be made to the information of the copy of the object part group in the lower layer of the latter subsystem, resulting in redundant maintenance work
[0014] Although the copy and the original have the same content, it requires twice the amount of useless memory in the computer

Embodiment Construction
[0046] The best way to carry out the invention
[0047] Fig. 1 is a block diagram showing the structure of an embodiment of the system design support device of the present invention. The device has a plurality of functional blocks that realize functions required for system design as low-level components, and high-level functional blocks are created by combining them. As a means of doing this, for example, using figure 2 A personal computer system 1 is shown. The personal computer system 1 includes: a main body 2, which accommodates memory such as a CPU and a hard disk commonly referred to as hardware; a CRT (or liquid crystal) display 5 and a printer 6, as an output device; a keyboard 3 and a mouse 4, as an input device, and FDD (floppy disc driver, floppy disk drive) and CDD (CD-ROM driver, CD-ROM drive), as input and output devices. The structure of the system design support device of the present invention is divided into parts having the following fu...

A system designing support apparatus is adapted to produce an upper composite function block by combining a pluality of function blocks as lower constituent elements which have the functions necessary for system designing. This apparatus is provided with an information presenting section adapted to take out the attributes of the lower function blocks, and present information used by the operator to designate the attributes as upper block inherent attributes or the information shared by both upper and lower blocks, a designation input section used by the operator to designate the attributes of the lower function blocks as inherent attributes or common information on the basis of the presented information, an inherent information registration section for registering, when the operator designates the inherent attributes, the attributes as inherent attributes, an inherent information storage section for storing the inherent attributes, and a common information storage section for storing the information other than the inherent attributes as common information. Thereby the inherent attributes and common information in the upper composite blocks can be discriminated from each other, and used.
Description
field of invention [0001] The present invention relates to a system design support device for supporting software production (programming) or design required for system development. Background technique [0002] An arithmetic processor used to control a system such as a plant is composed of multiple elements (hereinafter referred to as "function blocks") that realize basic functions such as addition and multiplication, or any combination thereof (referred to as "composite functions"). These elements include not only programs for realizing required functions, but also hardware circuits. These elements may be understood as "components" or "modules". Especially in the field of software technology, these parts are called "object parts" because they belong to the concept "object". Combining several object parts creates a group of object parts (called "composite object parts") with specific functions. A compound object part can be expressed as a compoun...
