Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a computer aided
The present invention relates to a circuit diagram input device for use in ``design''.

[Prior art]

Generally, a circuit diagram has circuit symbols 21.22, which are logical symbols, and circuit symbols 21.22, as shown in FIG.
It is constituted by connection lines 23 and 24 expressing the connection relationship. Further, circuit diagrams are often created in units of devices or boards, etc., and cannot be expressed on four sheets of paper, so they usually consist of several to several dozen pages. In order to express the connection between each page, the signal name for connection between pages (
(hereinafter simply abbreviated as "signal name") is expressed using 25.26. The third example shows connections between pages using signal names.
What connects Figures 3A and 3B shown in Figures A and 3B are signal names 31.32 and 33.34,
A connection is expressed by signal names with the same name. That is, in Figures 3A and 3B, the signal name (ABCD)
31 and signal name (ABCD) 33. Signal name CEFGH)3
2 and signal name 34 (EFGH) are each connected.

Next, a circuit diagram input device in a CAD system will be explained. FIG. 4 is a functional configuration diagram of a conventional circuit diagram input device. In the figure, 41 is an input/output control section, 42 is a circuit diagram data storage section, 43 is a circuit diagram symbol storage section, and 44 is a circuit diagram data storage section.
is the command control section. The input control section 41 includes a keyboard 45. Accepts input from mouse 46, etc., and converts the circuit diagram to C.
Display on RT47 etc. The circuit diagram data storage section 42 stores this input data page by page.

Further, in accordance with a command input from the keyboard 45, circuit symbol data registered in the circuit symbol storage section 43 may be read out and stored as part of the circuit data. The circuit symbol storage unit 43 stores information on pictures (straight lines, circular arcs), etc. of circuit symbol data that are part of a circuit diagram.

Next, a method for inputting a circuit diagram using the circuit diagram input device having the above configuration will be explained. As shown in FIG. 5, circuit symbols 52 are placed within a drawing frame 51 representing the large scale of the drawing, and then connecting lines 53 are used to express connections between the necessary circuit symbols. When inputting signals, for example, in the state shown in FIG. 6, end points 74 to 76 of the connection lines 71 to 73 are selected as shown in FIG. 7, and the signals ABCD77, EFGH78, I JKL7 are
9 is input by the operator operating the circuit diagram input device using the keyboard 45 to express the connection relationship between pages. The data input in this way is stored in the circuit diagram data storage unit 4.
2 are sequentially stored.

[Problem to be solved by the invention]

However, in the conventional circuit diagram input device described above, when inputting a signal name, the necessary signal name must be entered from the keyboard 45 for each page, but the signal name indicates the connection between pages. Since it is used for expression, there are always two or more. Therefore, when expressing a circuit over multiple pages, the operator always inputs the same signal name two or more times. Therefore, there is a risk that it takes a long time to input the signal name, input errors occur, and things that should originally be connected are not connected.

The present invention has been developed in view of the above-mentioned points, and eliminates the waste of inputting the same signal name from the keyboard more than once in the conventional circuit diagram input device, simplifies the input of signal names, and improves the user experience. The objective is to improve the machine interface and provide a device with excellent input efficiency.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a circuit diagram input device in a CAD system with a storage means for storing signal names connecting pages attached to circuit diagrams that have already been input. Display a list of the signal names,
The system is characterized in that the operator can select and input a desired signal name from among the signal names.

[Effect]

As mentioned above, a storage means is provided to store the names of signals connecting pages attached to circuit diagrams that have already been input, and when inputting signal names, the names of signals attached to circuit diagrams that have already been input are displayed. Since the operator can select the signal name, it is possible to eliminate waste and mistakes when inputting the signal name.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figure 1 shows a CA for implementing the circuit diagram input method of the present invention.
It is a diagram showing the functional configuration of a circuit diagram input device of the D system. In the figure, an input/output control section 11, a circuit diagram data storage section 12, a circuit diagram symbol storage section 13, a command control section 1
4, the keyboard 16, the mouse 17, and the CRT 18 respectively include the input/output control section 41, circuit diagram data storage section 42, circuit symbol storage section 43, and command control section 44 shown in FIG.
The keyboard 45, mouse 46 and CRT 47 are the same. The signal name storage section 15 stores all pages of signal names input from the keyboard 16 that connect pages.

The operation of the circuit diagram input device having the above configuration will be explained using the flowchart shown in FIG. First, as in the past, the operator inputs the position where the signal name is to be added, that is, the endpoint (see endpoints 74, 75, and 76 in FIG. 7), is accepted (step 501), and then the signal name is input from the keyboard 16. (A in Figure 7
BCD, EFGH, IJKL) is accepted (step 502). At this time, special instructions from the operator (
(detailed later)) (Step 5)
03). If there is no special instruction, the input signal name (character string) is added to the circuit diagram data storage section 12 in the same way as conventional signal name input (step 504). Furthermore, in the present invention, a search is made to see if the signal name input this time already exists in the signal name storage unit 5 (step 505), and if it does not exist, the signal name is additionally stored in the signal name storage unit 15 (step 505). 806).

Next, the case where there is a special instruction in step 803 will be described. Here, a special instruction is when a special key predetermined on the keyboard is pressed, or when the input character string contains special characters. If the character "*" is entered in a character string, it is determined to be a special instruction. In this case, all signal names existing in the signal name storage section 15 are CR
In step 507 (as shown in T18), input from the operator is accepted. The operator uses the mouse 17,
Select an input signal name by moving the cursor over any signal name displayed on the screen (step 80).
8). Next, the selected signal name is additionally stored in the circuit diagram data storage section 12 in the same way as the signal name input from the keyboard 16 (step 5O9).

To illustrate the above operation, first, if there is no special instruction, accept the input of the end point of the connection line 91 as shown in FIG. input. And this signal name ABC
D is additionally stored in the signal name storage section 15. special instructions,
That is, as shown in FIG. 9(b), when the character "*゛'' is entered at the end point of the connection line 92, a predetermined range of signal names that have been stored in the signal name storage section 15 is displayed on the CRT 18, and this If there is a desired signal name in the predetermined range, select the signal name (in this case ABCD) by moving the cursor or the like.Next, as shown in FIG. This signal name (ABCD here) is additionally stored from the signal name storage section 15 into the circuit diagram data storage section 12.

In addition, when displaying signal names on the screen, it is more convenient to sort them alphabetically for selection.Also, as the number of circuit diagrams increases, the number of signal names also increases, so the operator can select the desired signal name. The selection process may be difficult, and in such cases, for example, if AB* is input from the keyboard 16, it may be possible to display only signals starting with AB on the screen. In this way, even if the signal name is long like 'ABCDEWXYZ', it is enough to input AB* and select from several signal names displayed.

Also, in any case, means for scrolling the range is required in case all of the signal names that must be displayed cannot be displayed on the screen.

Although this embodiment shows an example in which the signal name storage section 15 is provided, the circuit diagram input method according to the present invention can be realized without providing the signal name storage section 15; In FIG. 8, step SOS and step S06 are no longer necessary, and in step SO7, the circuit diagram data storage unit 12
All you have to do is extract all the signal names in the file and display them on the screen.
However, in this case, the processing time of step 807 will be longer,
In some cases, it may not be possible to guarantee a response that the operator is satisfied with.

〔Effect of the invention〕

As explained above, according to the present invention, when inputting a signal name, the signal name attached to the circuit diagram that has already been input is displayed so that the operator can select it. It can be expected to have the excellent effect of eliminating waste and mistakes and improving input efficiency.
