Abstract

PURPOSE:To reduce the designing manhour of a circuit designer and to maintain the circuit quality by displaying collectively all electronic circuit diagrams which cover >=2 different pages and have the connecting relations among the circuit elements on an output device. CONSTITUTION:A signal name SIG given to an output terminal of a circuit element A is inputted to a connection retrieving part 3a of a picture data arithmetic processor 3 from a retrieving signal input device 1. The part 3a retrieves first the connecting relation in an electronic circuit diagram I only with the retrieving carried out in the same page and recognizes the presence of the connecting relation based on a fact that the pointed signal name SIG is given to the input terminals of circuit elements B and C. Then the part 3a retrieves a fact that the connecting relation is also secured among the circuit elements D, E and F of the electronic circuit diagrams II and III. These connecting relations are turned into the data so that the circuit diagrams I-III obtained through the editing and retrieving performed by an output picture producer can be displayed en bloc on the same screen. Then the picture output is sent to a batch display device 2. Thus the electronic circuits can be easily set and the circuit quality is maintained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic circuit diagram search and display system, and particularly to a system for searching and displaying connection circuit diagrams input across different pages.

(Prior Art) Conventionally, in this type of electronic circuit diagram search and display system, the connection relationships of circuit elements can usually be searched only between circuit diagrams input on the same page.

(Problems to be Solved by the Invention) In the conventional electronic circuit diagram search and display system described above, it is not possible to search or collectively display connection relationships between circuit elements across different pages. For this reason, design errors are likely to occur in the connections between circuit elements in circuit design work, resulting in an increase in design man-hours when making circuit corrections and a disadvantage in that the quality of the designed circuit deteriorates.

(Means for Solving the Problems) An electronic circuit diagram search and display system according to the present invention includes a search signal input device, an image data processing device including a connection search section and an output image creation section, and an electronic circuit diagram image data storage. the image data arithmetic processing device responds to a search signal inputted from the line signal input device and inputs a signal name indicated by the search signal into an input circuit element. The apparatus further comprises image data processing means for reading out all electronic circuit diagram data to be attached to the output terminal from the electronic circuit diagram image data storage device, editing it into a pattern display image output, and outputting it to the image ratio car collective display device. In this way, the connection relationships between circuit elements across two or more pages are searched for and displayed all at once.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Embodiment) FIGS. 1 and 2 are a block diagram of an electronic circuit diagram search and display system and a flowchart of its controller +11ff, respectively, showing an embodiment of the present invention.

The electronic circuit diagram search and display system of this embodiment includes a search signal input device 1, an image ratio display device 2, a connection search section 3a for searching connection relationships between circuit elements, and an output image creation section 3b. It is composed of an arithmetic processing device 3 and an electronic circuit diagram image data storage device 4.

Next, the drawing search display procedure of the above embodiment will be explained using the flowchart of FIG.

FIGS. 3(a), 3(b), and 3(c) each show three circuit diagrams related to input data input across a plurality of pages in the memory WW.

Here, a case will be described in which, using these three electronic circuit diagrams, all connection relationships between the circuit element A of the electronic circuit diagram I and other circuit elements are searched and displayed with a - pattern in order to change or confirm the design of the circuit. First, the signal name (S I G) attached to the output terminal to the circuit element is input from the search signal input device 1 to the connection search section 3a of the image data arithmetic processing device 3 (step 11).

The connection search unit 3a thereby searches the designated signal name (
Start the process of extracting all SIG) (Step 1
2) 6 First, the connection relationships only within the electronic storage diagram 1 are searched for within the same page (step 13), and the
, C has the designated signal name (SIG) attached to its input terminal, so it is recognized that there is a connection relationship. Next, it is determined whether there is a connection relationship between different pages (step 14), and the circuit elements of the electronic circuit diagrams ■, ■,
It is found that there is a connection relationship between E and F (step 15), and the three electronic circuit diagrams I, ■, and ■ that are edited and retrieved in output image creation are displayed on the same screen. The image is converted into data so that it can be displayed, and the image output is sent to the batch display device W2 (step 16). At this time, the connection signal line is highlighted in a different color from other signal lines (step 17).

FIG. 4 is an image diagram of the output circuit diagram displayed according to the above embodiment, in which connection signal lines are highlighted and identified using colors different from other signal lines.

(Effects of the Invention) As described above in detail, according to the present invention, all electronic circuit diagrams having connection relationships between circuit elements across two or more different pages are displayed at once on an output device. This has the effect of reducing design man-hours for circuit designers and maintaining circuit quality.
