Abstract

PURPOSE:To perform a division designing work on a block diagram editor, to reduce the man-hour of work processes, to improve the quality of the division designing and to drastically reduce the number of modification man-hour due to associated work mistakes. CONSTITUTION:The block diagram editor consists of an input/output device 1, an operation processing device 2, a data storage device 3 and a block diagram editor mechanism 4. In the block diagram editor mechanism 4, the division and designing of a block diagram is performed by means of a division line editing part 5 defining a division line indicating the border of block diagram division areas and a division label editing part 6 defining a division label indicating the division regions for a symbol comprising the division areas or the block diagram. A division designing verification part 7 verifies the legality of the divided and designed block diagram and a division circuit information generation part 8 automatically generates division circuit information from the divided and designed block diagram.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block division method for a block diagram editor of an electronic circuit device.

[0002]

2. Description of the Related Art A conventional block diagram editor does not have a drawing constituent element or a symbol dedicated to division, so that a block division design is performed using a constituent element having no attribute.
The verification of the divided design and the generation of the divided circuit information were done manually.

[0003]

This conventional block diagram editor does not have a drawing constituent element dedicated to the division definition, so that there is a problem that the drawing representation dedicated to the block diagram division design cannot be performed. In addition, since verification after division design and generation of division circuit information were done manually, not only it takes time, but also quality is deteriorated due to verification errors and generation errors.
There was a problem that the man-hour increased with the correction work.

[0004]

According to the block division method of the present invention, boundaries of block diagram division areas are defined in the block division method of dividing a block diagram of an electronic circuit device on a block diagram editor to cut out a circuit. A dividing line editing means, a dividing label editing means for defining a dividing division for the symbols constituting the divided area or block diagram,
A division design verification means for verifying the correctness of the division definition, and a division circuit information generation means for automatically generating division circuit information from the block diagram divided and designed by the division line editing means, the division label editing means and the division design verification means. Is equipped with.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a block diagram editor showing an embodiment of a block division method of the present invention, FIG. 2 is a flow diagram showing an operation flow of the block diagram editor mechanism in FIG.
FIG. 3 is a diagram showing an example of a window structure in this embodiment.

The block diagram editor of this embodiment comprises an input / output unit 1, an arithmetic processing unit 2, a data storage unit 3 and a block diagram editor mechanism 4. In the block diagram editor mechanism 4, a dividing line editing unit 5 that defines a dividing line that indicates the boundary of the block diagram dividing region, and a dividing label edit that defines a dividing label that indicates a dividing division for the symbols that form the dividing region or the block diagram. The division design of the block diagram is performed by the unit 6. Then, the division design verification unit 7 verifies the correctness of the divided design block diagram, and the divided circuit information generation unit 8 automatically generates divided circuit information from the block diagram for which the division design is completed.

Next, the operation of this embodiment will be described with reference to FIG. After the dividing line editing unit 5 and the dividing label editing unit 6 edit the dividing line and the dividing label on the block diagram editor to perform the dividing design (step 21), the verification is performed (step 22). Next, when the verification result is judged and the design error is verified (No in step 23), the process returns to step 21 to perform the modified design. If there is no design error (Yes in step 23), divided circuit information is automatically generated (step 25).

Next, in FIG. 3, a graphic window 31 displays a block diagram and gives instructions for division editing. The menu window 36 gives an instruction to activate each command of the block diagram editor. The components necessary for the division definition are the division line 33 and the division label 32, the former defining the boundaries of the division areas, and the latter defining the divisions of the division areas. A division label can also be defined for the symbol 34 that is a component of the block diagram. When the command split check 39 is activated, the split design is verified and the result is displayed in the message window 35 and the text window 40.

[0009]

As described above, according to the present invention, the block diagram editor mechanism for designing the block diagram of the electronic circuit device includes the dividing line editing means, the dividing label editing means, the dividing design verifying means, and the divided circuit information generating means. With the provision, it becomes possible to perform the division design work on the block diagram editor, and the division design verification and the division circuit information generation can be automatically processed. This has the effect of significantly reducing the number of correction steps.
