Description

Circuit diagram editing apparatus and circuit diagram editing program

The present invention relates to a circuit diagram editing apparatus and a circuit diagram editing program for efficiently editing a circuit diagram.

Many circuit diagram editing devices use a pointing device such as a mouse to locate the position on the circuit diagram where changes are to be made, such as placing circuit elements or signal names, or connecting terminals with wires. A method of designating is used (hereinafter, a position on a circuit diagram where a change is made by a user's editing operation is called an editing position).
In a general circuit diagram editing apparatus, in order for the user to specify an editing position, the user moves the mouse cursor to a desired position on the circuit diagram using the mouse, and then presses the left button of the mouse. It is necessary to perform an operation.

However, the above-described method has a problem that the user spends a lot of effort on operating the mouse, and the work efficiency of circuit diagram editing is significantly impaired. The reason why the user's labor is large in this problem is that, as the first factor, the amount of user's movement required to move the mouse cursor around the desired terminal or wiring is large, and as the second factor, For example, it is difficult to position the mouse cursor so that a desired terminal or wiring is pointed exactly.

Regarding the difficulty of the operation mentioned as the second factor, in the conventional circuit diagram editing apparatus, the position of the mouse cursor when the user clicks (hereinafter referred to as the click position of the mouse cursor at the time of click). In some cases, the difficulty of operation is alleviated by setting a terminal existing in the vicinity of the terminal as an editing position (see, for example, Patent Document 1). Further, in the circuit diagram editing apparatus as shown in Patent Document 1, when a user instructs connection of wiring, a connection is made when there are a plurality of unconnected terminals in a certain area centered on the mouse cursor. By determining the terminal according to the priority order in which the terminals are defined in advance, when there are a plurality of terminals at the same distance from the mouse cursor, it is clarified which terminal is connected.

For example, as shown in Patent Document 2, when there are a plurality of terminals in the vicinity of the click position, the circuit diagram editing apparatus selects a terminal candidate to be set at the edit position according to a predetermined priority order. If the user rejects the presented terminal, the circuit diagram editing apparatus selects the terminal that occupies the next rank in the priority order and presents it to the user. There was something that was repeated until the user adopted it.

By the way, when analyzing the characteristics of the location that becomes the editing position in the editing of the circuit diagram, the end point of the unconnected terminal or the unconnected wiring or the unconnected signal name (hereinafter, the end point of the unconnected terminal or the unconnected wiring) In many cases, a location that satisfies a specific condition in the circuit diagram being edited is set as an editing position (hereinafter, a predetermined condition is satisfied). A location on the circuit is called a feature location). In addition to the open end, the characteristic part includes a signal name, a circuit element, a wiring, a terminal, or an end point of the wiring.
In other words, if the operation of setting the characteristic part to the editing position can be simplified, the work efficiency of circuit diagram editing can be greatly improved.

Conventionally, for example, there has been a circuit diagram editing apparatus disclosed in Patent Document 3 as a technique that focuses on a characteristic part in a circuit diagram being edited. This circuit diagram editing device is a circuit that does not have an open end by the circuit diagram editing device inspecting the connection state of the terminal that is the target of the placement or wiring every time the user executes the placement or wiring of the circuit element. The elements are displayed on the screen with emphasis over the circuit elements with open ends.

JP-A-6-124316 (page 2, lines 1 to 9, lines 47 to 55, FIG. 3) JP-A-9-101980 (page 2, lines 1 to 48, FIG. 3) Japanese Patent Laid-Open No. 5-101128 (page 1, lines 4 to 11, FIG. 1)

However, in any of the above conventional circuit diagram editing apparatuses, no substantial improvement has been attempted with respect to the magnitude of the operation amount cited as the first factor, and an operation for designating an editing position ( In the following, the user's effort for designating the edit position is referred to as edit position designation) remains large.

The present invention has been made to solve the above-described problems, and is a circuit diagram editing apparatus and a circuit diagram editing program capable of reducing an editing position designation task in editing a circuit diagram and improving the efficiency of editing work. The purpose is to obtain.

A circuit diagram editing apparatus according to the present invention includes an editing position management unit that manages an editing position that is a position on a circuit that exerts an effect of an editing operation, and a feature part that is a part that satisfies a predetermined condition in the circuit being edited The edit position management unit sets the edit position to the position of the feature part detected by the feature part detection unit when the content of the editing operation is movement to the feature part. It is what I did. As a result, it is possible to reduce the labor for designating the editing position in editing the circuit diagram and to improve the editing work.

Further, information on circuit elements managed by the circuit element catalog management unit 5 is stored in the HDD 104. The display unit 9 is realized by a graphic chip 107, a frame buffer 108, and a display monitor 109.

Next, circuit diagram data targeted by the circuit diagram editing apparatus of the present embodiment will be described.
The user can create a new circuit diagram or read data already created. In the case of newly creating, internal information of the edit data management unit 2 and the edit position management unit 4 is initialized by performing a predetermined operation in the input unit 1. When data is read, by performing a predetermined operation in the input unit 1, the editing data management unit 2 and the removable data inserted into the HDD 104 or a removable media input / output device (both of which are not shown) Data is read into the editing position management unit 4 and internal information is set.

The editing position, which is internal information of the editing position management unit 4, is a coordinate. The editing position may be represented by coordinate points, or may have a height and width like a cursor of a computer or the like. If it has a height and width, its coordinates are represented by the center position of the rectangle.
The circuit diagram data that is internal information of the editing data management unit 2 is composed of one or a plurality of network data columns. One network data is composed of a sequence of one or a plurality of circuit component data. One piece of circuit component data includes information of “ID”, “type”, “name”, “coordinates”, and “connection destination list” (see FIG. 4 described later).
“ID” is a numerical value or a character string according to a certain format for distinguishing individual circuit components. “Type” includes a signal name and wiring in addition to various circuit elements. “Name” is a character string displayed on the circuit diagram as the name of the circuit component. “Coordinates” are plane coordinates having a predetermined point on the drawing where the circuit is arranged as the origin, the right direction as the X coordinate, and the lower direction as the Y coordinate. The “connection destination list”, when the circuit component is a circuit element, holds the “connection destination identifier” of each terminal (one or more) connected to each terminal as many as the number of terminals of the circuit element. To do. The “connection destination identifier” is identification information for specifying the ID of the circuit component to which the terminal that is the connection destination belongs and the position of the terminal in the circuit component. When the circuit component is a signal name, the “connection destination list” holds one or more connection destination identifiers on either the left or right side of the signal name. Are stored as connection destination identifiers (one or more).

FIG. 3 is an explanatory diagram illustrating an example of a network. Hereinafter, the contents of the network data will be described using this.
In the figure, a character string 51, a character string 52, and a character string 53 are signal names to be input to the circuit, and a character string 54 is a signal name to be an output of the circuit. A circuit connects these inputs and outputs. The rectangle 55 and the rectangle 56 are circuit elements. The circuit element 55 is a circuit element of a type called ADD, and is a circuit element that outputs the sum of input values. The circuit element 56 is a circuit element of a type called SUB, and is a circuit element that outputs a difference between input values. A straight line 57, a straight line 58, a straight line 59, a broken line 60, and a straight line 61 are wirings. Each wiring either connects one signal name and one terminal of the circuit element, or connects between two terminals of the circuit element. That is, the network data of this example is composed of two circuit elements, four signal names, and five wires.

FIG. 4 is an explanatory diagram showing the configuration contents of the network data.
The relationship between the ID in FIG. 4, the signal name in FIG. 3, the wiring, and the circuit element is as follows.
The ID of the character string 51 in FIG. 3 is 1, the ID of the character string 52 is 3, the ID of the character string 53 is 5, and the ID of the character string 54 is 11. The ID of the circuit element 55 is 7, and the ID of the circuit element 56 is 9. The ID of the wiring 57 is 2, the ID of the wiring 58 is 4, the ID of the wiring 59 is 6, the ID of the wiring 60 is 8, and the ID of the wiring 61 is 10. For the connection destination identifier in the connection destination list, a character string in which the position of the terminal in the circuit component is entered in parentheses following the ID. However, the character string “0” is used for an unconnected terminal, an end point of an unconnected wiring, or an open end connection destination identifier which is an unconnected signal name. Since there is no open end in the network of FIG. 3, there is no connection destination identifier of the open end in FIG. In the coordinate system, the X coordinate at the left end of the character string 53 is 0, and the Y coordinate of the character string 51 is 0.

Next, the operation of the circuit diagram editing apparatus according to the first embodiment will be described.
In the following, a case where the open end is a feature part will be described as an example of the feature part.
When the input unit 1 instructs to move the editing position by a predetermined operation by the user, the instruction is transmitted from the input unit 1 to the editing position management unit 4. When the instruction from the user is the XY coordinate to which the editing position is to be moved, the editing position management unit 4 updates the internal editing position information (XY coordinate) to the instructed XY coordinate, and the editing data management unit 2 tells the editing position information. When the instruction from the user is the direction and distance to move the editing position, the editing position management unit 4 updates the internal editing position information to the XY coordinates moved by the designated distance in the designated direction. Then, the editing data management unit 2 is notified of the editing position information. When the instruction from the user is to move the edit position to the open end, the edit position management unit 4 acquires the open end present in the edit data from the feature part detection unit 3, and the XY coordinates thereof The editing position information inside is updated and the editing position information is transmitted to the editing data management unit 2. When the editing data management unit 2 receives the editing position information from the editing position management unit 4, the editing data management unit 2 instructs the display unit 9 to update the display. The display unit 9 creates display data based on the editing position information obtained from the editing position management unit 4 and the circuit diagram data managed by the editing data management unit 2, and updates the display.

Here, the operation when the characteristic part detection unit 3 detects the open end existing in the circuit diagram data being edited and acquires the coordinates thereof will be described.
The characteristic part detection unit 3 acquires the network data held by the editing data management unit 2 and searches for an open end from the connection destination list. As described above, whether or not the terminal is an open end can be easily determined depending on whether the connection destination identifier indicates an open end or a connection destination terminal. The editing position management unit 4 combines the position of the open end in the circuit component with the coordinates of the circuit component to which the open end belongs, which is acquired from the feature part detection unit 3 by searching for the open end, and sets the coordinate of the open end. get.

The editing position moving process based on the detection of the open end will be described with reference to the drawings.
FIG. 5 is an example in which a circuit diagram is displayed on the display monitor 109 corresponding to the display unit 9 of the present invention.
In the figure, a straight line 62 is an open end, and an arrow 63 is a mouse cursor. The circuit shown in FIG. 5 is equivalent to a network obtained by removing the character string 53 and the wiring 59 from the network shown in FIG. That is, in the network data shown in FIG. 4, there is no signal name “gamma” of ID5, and the value of the connection destination list of the wiring of ID6 is equivalent to input 1 = 0 and output 1 = 7 (input 2). The editing position is always set to the position of the mouse cursor, and the user can move the mouse cursor to an arbitrary position by operating the mouse 102.

The case where the edit position is set at the open end 62 with respect to the circuit diagram of FIG. 5 will be described. When the user instructs to move the editing position to the open end by a predetermined operation such as pressing the TAB key, this instruction is transmitted from the input unit 1 to the editing position management unit 4, and the editing position management unit that has received this instruction. 4 acquires an open end from the feature part detection unit 3.

FIG. 6 is a flowchart showing the process of moving the mouse cursor to the open end. Each process will be described below.
(Step ST101) The characteristic part detection unit 3 acquires network data from the editing data management unit 2.
(Steps ST102, ST103, ST104) The characteristic part detection unit 3 indicates that the connection destination identifier is an open end from the acquired network data (that is, the connection destination identifier is “0”). When the part is searched and the corresponding circuit part is found, the circuit part data of the circuit part is transmitted to the editing position management unit 4. If there is no corresponding circuit component, the characteristic part detection unit 3 notifies the editing position management unit 4 that there is no open end.
(Steps ST105 and ST106) When the editing position management unit 4 receives the circuit component data from the feature part detection unit 3, the editing position management unit 4 combines the coordinate information of the circuit component data and the connection destination list information of the circuit component data to open the end. , The internal editing position information is updated to the coordinates, and the editing position coordinates are transmitted to the editing data management unit 2. On the other hand, when the editing position management unit 4 is notified from the feature part detection unit 3 that there is no open end, the editing position management unit 4 stops the editing position moving process.
(Step ST107) The edit data management unit 2 updates the internal edit position information to the edit position coordinates received from the edit position management unit 4, and instructs the display unit 9 to update the display.
(Step ST108) When the display unit 9 is instructed to update the display from the editing data management unit 2, the display unit 9 creates display data based on the coordinates of the editing position obtained from the editing data management unit 2 and the circuit diagram data. , Update the display.
With the above processing, a circuit diagram as shown in FIG. 7 is displayed indicating that the position of the mouse cursor as the editing position is the open end.

In the above example, the feature part detection unit 3 uses an open end as a part that satisfies a predetermined condition, but may be a part other than this. The condition is obtained by the following combination.
Condition = OBJECTandIN_OUTandCONNECTION
However,
OBJECT = signal name or circuit element or wiring or terminal or wiring end point or comment IN_OUT = input or output or ignore CONNECTION = connected or not connected or ignored That is, OBJECT is an object to be edited on a circuit diagram such as a wiring or a circuit element. It is all that becomes. Comments are various descriptions relating to circuit diagrams. Further, IN_OUT is an element for designating input / output when OBJECT has input / output. Furthermore, CONNECTION is an element indicating whether or not a wiring or signal is connected to OBJECT. “Ignore” indicates that either is acceptable.

As a result of the logical product of such elements, as a characteristic part, a signal name existing in the circuit being edited, a circuit element, a wiring, a terminal, a wiring end point, a terminal on the input side, or a wiring input -Side end point, or output-side terminal, or output-side end point, or connected signal name, or a circuit element that does not have an unconnected terminal, or connected wiring, or connected terminal, or connection Connected input terminal, connected input terminal, connected output terminal, connected output terminal, connected output terminal, or unconnected Signal name, circuit element with unconnected terminal, unconnected terminal, unconnected wiring end point, unconnected input side terminal, unconnected wiring input side end point, or unconnected Output side terminal or unconnected wiring output Can be the characteristic portions of the end points, or in any type select one of such comments.

In the above example, the TAB key is pressed as the operation for instructing the movement of the editing position to the open end. However, any key operation or mouse operation may be used. Further, for example, by performing simultaneous operation of a plurality of keys such as CTRL + TAB, it is possible to set a movement instruction to a feature part different from the open end.

As described above, according to the circuit diagram editing apparatus of the first embodiment, the editing position management unit that manages the editing position that is the position on the circuit that exerts the effect of the editing operation, and the circuit being edited are predetermined. A feature part detection unit that detects a feature part that satisfies a condition, and the editing position management unit detects the feature part detected by the feature part detection unit when the content of the editing operation is movement to the feature part. Since the editing position is set to the position of (2), the editing position can be moved to a characteristic part such as an open end in the editing of the circuit diagram with one touch, so that the work efficiency in editing the circuit diagram can be improved.

Further, according to the circuit diagram editing apparatus of the first embodiment, the predetermined condition is given by the logical product of OBJECT, IN_OUT, and CONNECTION, so that all the objects to be edited on the circuit diagram Can be detected as a characteristic part.

Further, according to the circuit diagram editing program of the first embodiment, the computer that edits the circuit diagram includes the editing position management unit that manages the editing position that is the position on the circuit that exerts the effect of the editing operation, and the editing in progress. When the circuit functions as a feature part detection unit that detects a feature part that satisfies a predetermined condition in the circuit, and the editing position management unit moves the feature to the feature part, Since the function for setting the editing position to the position of the characteristic part detected by the part detection unit is provided, a circuit diagram editing apparatus capable of improving the work efficiency in editing the circuit diagram can be realized on the computer. .

Embodiment 2. FIG.
In the second embodiment, when a user performs a predetermined operation for moving an editing position to a feature part, a feature part of a type determined according to a predetermined transition order is detected, and the position of the feature part is detected. The editing position is set. That is, the editing position management unit 4 of the second embodiment has data indicating a predetermined transition order, and when the content of the editing operation is movement to a characteristic part, based on the transition order, The edit position is set to the position to the feature part detected by the feature part detection unit 3. The other configuration is the same as that of the first embodiment, and will be described below using the configuration of FIG.

FIG. 8 is an explanatory diagram showing an example of a network, and FIG. 9 shows a configuration content of network data of the network shown in FIG.
Hereinafter, the operation of the second embodiment will be described using the illustrated example. In order to avoid complicated explanation, in the following explanation, the input side terminal and the output side terminal of the circuit element are used as characteristic parts, and the transition position of the editing position is changed by the user from the editing position to the characteristic part. If the pre-movement editing position, which is the editing position when the predetermined operation is performed, is an input-side terminal, the post-movement editing that is the destination of the editing position is set to the output-side terminal of the circuit element to which the terminal belongs. In the case where the edit position before movement is a terminal on the output side, the case where the terminal on the input side of the circuit element to which the terminal belongs is set as the edit position after movement will be described. However, also in the second embodiment, there are various candidates for feature parts, and it is the same as in the first embodiment that a circuit diagram editing apparatus can be easily realized by arbitrarily selecting them. As for the edit position transition order, if the edit position before movement is an end point on the input side of the wiring, the end point on the output side of the wiring to which that end point belongs is set as the edit position after movement, and the edit position before movement is the wiring position. In the case of the output-side end point, there may be various ways of determination depending on the user's preference regarding the procedure for proceeding with the circuit editing, such as setting the input-side end point of the wiring to which the end point belongs as the edit position after movement. In FIG. 8, a straight line 64, a straight line 65, and a straight line 66 are all open ends, and an arrow 67 is a mouse cursor. Further, the wiring of ID2 in FIG. 9 is data corresponding to the straight line 68 in FIG.

Hereinafter, when the user designates the movement of the editing position to the characteristic part, the type of the characteristic part that is the movement destination of the editing position is determined according to a predetermined transition order, and the characteristic part of that type is being edited. An example of a function for detecting from the circuit and setting the editing position to the detected position of the characteristic part will be described. The following processing starts from the state shown in FIG.
In the circuit diagram of FIG. 8, when the user instructs to move the editing position to the open end by a predetermined operation such as pressing the TAB key, this instruction is transmitted from the input unit 1 to the editing position management unit 4.

FIG. 10 is a flowchart showing a process of moving the mouse cursor to the open end, and each process will be described below.
(Step ST201) The editing position management unit 4 acquires network data from the editing data management unit 2.
(Steps ST202, ST203, ST204, ST205) The editing position management unit 4 collates the network data with the coordinates of the internal editing position information, and the current editing position is set to any terminal of any circuit element. To find out. When the corresponding terminal is found, the circuit component data of the circuit element to which the terminal belongs is checked to determine whether the terminal is the input side or the output side (that is, whether the terminal identification information is input or output) To see if it is). When the terminal is on the input side, the feature part detection unit 3 is requested to detect the output side terminal as the feature part. When the terminal is on the output side, the feature part detection unit 3 is characterized by the input side terminal. Requests detection as a site. If there is no corresponding terminal in the above search, the process proceeds to step ST106 and the editing position moving process is stopped.

(Step ST206) The characteristic part detection unit 3 acquires network data from the editing data management unit 2.
(Steps ST207, ST208, ST209) The feature part detection unit 3 has a circuit part having a feature part of the type specified by the editing position management unit 4 (that is, either the input side terminal or the output side terminal). Is searched from the network data, and when the corresponding circuit component is found, the circuit component data of the circuit component is transmitted to the editing position management unit 4. If there is no corresponding circuit component, the characteristic part detection unit 3 notifies the editing position management unit 4 that there is no open end.

Since the processing after the above is the same as the processing from step ST105 to step ST108 described in the first embodiment, description thereof is omitted here.

As a result of the above processing, if the mouse cursor indicating the editing position is the terminal on the input side when the user designates the movement of the editing position to the feature part, the output of the circuit element to which the terminal belongs is output. When the editing position at the above time is an output terminal, the terminal is moved to the input terminal position of the circuit element to which the terminal belongs, and the circuit shown in FIG. A figure is displayed. In FIG. 11, an arrow 69 indicates a mouse cursor.
Also in the second embodiment, the instruction to move to the characteristic part is not limited to the TAB key, but may be any key operation or mouse operation.

As described above, according to the circuit diagram editing apparatus of the second embodiment, the editing position management unit, when the content of the editing operation is movement to a characteristic part, based on a predetermined transition order, Since the editing position is set to the position of the characteristic part detected by the characteristic part detection unit, the user can easily set the position corresponding to the procedure for the user to edit the circuit diagram by simply performing the same operation. Since it can be set, the work efficiency in editing the circuit diagram can be improved.

Further, according to the circuit diagram editing apparatus of the second embodiment, when the current position is the OBJECT input side, the transition order is the transition to the OBJECT output side, and the current position is the OBJECT output side. , It is determined to make a transition to the input side of OBJECT, so that the order of transition can be made in accordance with the general operation procedure of the user, and the work efficiency in editing the circuit diagram can be improved.

Embodiment 3 FIG.
In the third embodiment, a part designated in advance by the user is excluded from the feature region detection range. That is, the edit position management unit 4 according to the third embodiment is configured so that the feature part detection unit 3 registers the exclusion part in the edit data to be detected as the feature part when the feature part exclusion part is input as the editing operation. It is configured. In addition, when the feature position detection unit 3 of the third embodiment is notified of the feature part detection from the editing position management unit 4, the feature part detection unit 3 detects the feature part by excluding the excluded part from the edited data in which the excluded part is registered. It is configured as follows. Since other configurations are the same as those in the first embodiment or the second embodiment, the following description will be made using the configuration in FIG.

FIG. 12 is an explanatory diagram showing an example of a network, and FIG. 13 is a configuration content of network data of the network shown in FIG.
The third embodiment will be described with reference to these drawings. In addition, in order to avoid the complexity of description, the case where an open end is used as a characteristic part will be described below. However, also in the third embodiment, the characteristic portion is not limited to the open end, and as described in the first embodiment, there are various candidates for the characteristic portion. The editing apparatus can be easily realized as in the first embodiment or the second embodiment. In FIG. 12, the straight line 70, the straight line 71, and the straight line 72 are all open ends. 13 is data corresponding to the straight line 73 in FIG. 12, and the wiring of ID4 is data corresponding to the broken line 74 in FIG.

Hereinafter, an example of a function for excluding a part designated by the user from the detection range of the characteristic part will be described.
(Processing 1) The user sets through the input unit 1 that the editing position is set at the open end 71 and is excluded from the feature region detection range.
(Process 2) The edit position management unit 4 that has received from the input unit 1 that the open end 71 is excluded from the feature region detection range is used as the connection destination identifier of the open end of the network data held by the edit data management unit 2 Register “−1”. FIG. 13 shows the configuration contents of the network data after rewriting the connection destination identifier of input 2 from “0” to “−1” in the connection destination list of the circuit element ADD of ID3.
After the above processing, when the input unit 1 instructs to move the editing position by a predetermined operation by the user, the above processing is performed by performing the same processing as in the first embodiment or the second embodiment. The location designated by the user in 1 can be excluded from the detection range of the open end.
Although the connection destination identifier is set to “−1”, any value may be used as long as it can identify the excluded portion.

As described above, according to the circuit diagram editing apparatus of the third embodiment, the editing position management unit sets the feature part detection unit as the feature part detection target when the exclusion part of the feature part is input as the editing operation. Since the excluded part is registered in the edit data, the feature part detection unit detects the feature part by excluding the excluded part in the edit data when the feature part detection is notified from the edit position management part. In the movement of the editing position to the open end in the editing of the figure, the open end not desired by the user is not set as the edit position. That is, according to the circuit diagram editing apparatus of the third embodiment, the editing position is not set to the terminal that is determined to remain open in the circuit diagram at the time of completion. The working efficiency can be further improved from the first embodiment.

Embodiment 4 FIG.
The fourth embodiment provides an operation method for directly specifying each feature part individually according to identification information individually assigned to all feature parts existing in the circuit being edited. A predetermined operation for selection is simplified. That is, in the fourth embodiment, identification information for individually identifying a characteristic part is given, and the editing position management unit 4 is provided with identification information of a characteristic part to which the editing position is moved in an editing operation. In addition, the editing position is set to the position of the characteristic part corresponding to the identification information detected by the characteristic part detection unit 3. The other configuration is the same as that of the first to third embodiments, and will be described below using the configuration of FIG.

FIG. 14 is an explanatory diagram showing an example of a network, and FIG. 15 shows the contents of the network data of the network shown in FIG. Hereinafter, the operation of the fourth embodiment will be described with reference to these drawings. For ease of explanation, the case where the open end is a characteristic part will be described. Also, as an example of the identification information to be assigned to each feature part, the number corresponding to the priority given to each feature part is set as the identification information, and the user has begun to specify the priority to move the edit position to the feature part. A case will be described in which the order is the open end closest to the editing position at the time. However, also in the fourth embodiment, the characteristic portion is not limited to the open end, and as described in the first embodiment, there are various candidates for the characteristic portion, and the circuit can be selected arbitrarily. The fact that the figure editing apparatus can be easily realized is the same as in the first to third embodiments. For the identification information given to the open end, the XY coordinates of each feature part may be used, or the direction of each feature part from the edit position when the user designates the edit position to move to the feature part. (Up / down / left / right or angle) may be used. Further, the priority order may be the order of the open end far from the editing position when the user designates the movement of the editing position to the feature part, or the user continuously moves the editing position to the feature part. When there are a plurality of open ends with the same X coordinate, the user continues to move to the feature part of the edit position. The priorities may be given in the order in which the Y coordinates are arranged in the order of closeness to the coordinates of the editing position at the time of starting.

Hereinafter, according to the identification information given to all the feature parts existing in the circuit being edited, an operation method for directly specifying each feature part individually is provided, and a predetermined method for the user to select a specific feature part is provided. An example for simplifying the operation will be described. The following processing starts from the state shown in FIG. In FIG. 14, a straight line 75, a straight line 76, and a straight line 77 are all open ends, and an arrow 78 is a mouse cursor. Further, the ID2 wiring in the network data of FIG. 15 corresponds to the straight line 79 in FIG. 14, and the ID4 wiring corresponds to the broken line 80 in FIG.

Suppose that the user instructs the movement of the editing position to the open end by a predetermined operation with respect to the circuit diagram of FIG.
FIG. 16 is a flowchart showing the process of moving the mouse cursor to the open end, and each process will be described below.
(Step ST401) The editing position management unit 4 stands by for a movement instruction from the input unit 1.
(Step ST402) When the editing position management unit 4 receives the movement instruction, the editing position management unit 4 requests the information on all open ends from the feature part detection unit 3.
(Steps ST403, ST404, ST405) The characteristic part detection unit 3 acquires network data from the editing data management unit 2, and the connection destination identifier is an open end from the network data (that is, the connection destination identifier is The circuit component data indicating "0") is searched, and the circuit component data of all the corresponding circuit components (that is, the circuit component ADD of ID3 and the circuit component SUB of ID5) are stored in the editing position management unit 4. introduce. If there is no corresponding circuit component, the characteristic part detection unit 3 notifies the editing position management unit 4 that there is no open end.

(Step ST406) When the editing position management unit 4 receives the circuit component data from the feature part detection unit 3, the editing position management unit 4 combines all the open ends by combining the coordinate information of the circuit component data and the connection destination list information of the circuit component data. (That is, the coordinates of ID3 circuit component ADD input 1 and input 2 and ID5 circuit component SUB output 1) are acquired, and the priority order is set in the order in which the open positions are located closer to the internal editing position information. (Ie, input 2 of ID3 circuit component ADD has the highest priority, then input 1 of ID3 circuit component ADD has the highest priority, and output 1 of ID5 circuit component SUB has the lowest priority) .
(Step ST407) The edit position management unit 4 updates the internal edit position information to the open end coordinates having the highest priority, and all the edit position coordinates and the priorities given above to the edit data management unit 2. The open end coordinates and rank are transmitted, and a list of open ends to which priority is given as described above is held.

(Step ST408) When the editing position management unit 4 is notified from the feature part detection unit 3 that there is no open end, the editing position management unit 4 stops the editing position moving process.
(Step ST409) The edit data management unit 2 updates the internal edit position information to the edit position coordinates received from the edit position management unit 4, and all the open end coordinates and ranks received from the edit position management unit 4 are displayed. And instruct the display unit 9 to update the display.
(Step ST410) When the display unit 9 is instructed to update the display, the display unit 9 performs display based on the coordinates of the editing position obtained from the editing data management unit 2, the coordinates and ranks of all open ends, and circuit diagram data. Create data and update the display.
With the above processing, the operation for moving the position of the mouse cursor, which is the editing position, to the open end with the highest priority and selecting the open end individually for all open ends existing in the edit data will be described. A circuit diagram as shown in FIG. 17 showing the guidance is displayed. In FIG. 17, a balloon 81, a balloon 82, and a balloon 83 are all guidance for explaining a predetermined operation for directly specifying a characteristic part, and an arrow 84 is a mouse cursor.

Subsequently, it is assumed that the user performs a predetermined operation (for example, pressing the key “2” on the keyboard) and designates a specific open end.
FIG. 18 is a flowchart showing the movement process to the open end.
The processing in the editing position management unit 4 that has received this designation is as follows.
(Step ST501) The editing position management unit 4 waits for an instruction to move from the input unit 1 to a specific open end.
(Steps ST502, ST503, ST504) When the editing position management unit 4 receives pressing of the key “2” as an instruction to move to a specific opening end, the editing position management unit 4 selects the opening end to which identification information corresponding to the key “2” is assigned. The search is performed from the list of open ends with priorities held in step ST406 described above. In this case, the editing position management unit 4 searches for an open end with priority 2 and, if there is an open end with priority 2, updates internal edit position information to the coordinates of the open end. Then, the coordinates of the editing position are transmitted to the editing data management unit 2. If there is no open end with a priority of 2, the editing position moving process is stopped.
(Step ST505) The edit data management unit 2 updates the internal edit position information to the edit position coordinates received from the edit position management unit 4, and instructs the display unit 9 to update the display.
(Step ST506) When the display unit 9 is instructed to update the display, the display unit 9 creates display data based on the coordinates of the editing position and the circuit diagram data obtained from the editing data management unit 2, and updates the display.

With the above processing, the mouse cursor indicating the editing position is moved to the open end (the terminal marked with “2” in FIG. 17) that is the output of the circuit element SUB at the upper right of the circuit diagram. A circuit diagram as shown in FIG. 19 is displayed.

In the above example, the numbers corresponding to all the priorities are displayed within the display range of the screen in the display unit 9, but the numbers of the priorities are displayed including those outside the display range. May be. In this case, the number of operation priorities may be displayed. If a priority number that is not displayed is designated, an area including the number is displayed (the screen scrolls). Or you may make it give a priority only to the open end in a display range. In addition, when the user cancels the movement of the editing position (for example, when the ESC key is pressed) instead of specifying the feature part to which the editing position is to be moved, the editing position is set to the position of the first priority. You may make it return.

In the above example, the numerical value of the priority is displayed as the identification information of the characteristic part. However, any information such as an alphabet may be used as long as it can be associated with the priority. In addition, even when information other than the priority order is used as the identification information of the feature part, such as the direction of each feature part from the edit position at the time when the user designates the movement of the edit position to the feature part, the feature part is specified. If possible, any information such as an arrow may be used. Furthermore, when a user can predict a predetermined operation for directly specifying a desired feature part and the guidance explaining the operation is an obstacle, the guidance is not displayed so as not to hide the circuit diagram. May be.

As described above, according to the circuit diagram editing apparatus of the fourth embodiment, an operation for assigning identification information to each feature part, providing means for designating the identification information from the input unit, and moving the editing position to the feature part In this case, when the identification information for the feature part to which the edit position is to be moved is designated, the edit position is set to the position of the feature part corresponding to the identification information. In other words, according to the circuit diagram editing apparatus of the fourth embodiment, the user can select the movement destination of the editing position from a plurality of feature parts with one operation. This can be further improved from Form 1.

Embodiment 5. FIG.
In the fifth embodiment, all the feature parts existing in the circuit being edited are given a rank according to a predetermined priority order, and the user continuously performs a predetermined operation for moving the edit position to the feature part. The editing position is set to the position of the feature part of the order that has been lowered by the number of times it has been performed. That is, the editing position management unit 4 of the fifth embodiment, when the content of the editing operation is movement to a characteristic part, based on the priority order of the characteristic part determined based on the editing position at the time of operation, The editing part is set to the position of the characteristic part detected by the characteristic part detection unit 3. The other configuration is the same as that of the first embodiment, the second embodiment, or the third embodiment, and will be described using the configuration of FIG.

The operation of the fifth embodiment will be described with reference to FIGS. In order to avoid complicated explanation, also in the fifth embodiment, the open end is used as a feature part, and the priority given to each feature part is continuously changed by the user to the feature part of the editing position. A case will be described in which the order of the open end is close to the editing position at the start of the designation. However, also in the fifth embodiment, the characteristic portion is not limited to the open end, and as described in the first embodiment, there are various candidates for the characteristic portion, and the circuit can be selected arbitrarily. As in the first to fourth embodiments, the diagram editing apparatus can be easily realized. In addition, as described in the fourth embodiment, there are various ways of determining the priority order to be given to the open end.

In the following, a ranking is assigned to the feature portion existing in the circuit being edited in accordance with a predetermined priority order, and the feature portion of the rank that has been lowered by the number of times the user has successively designated the movement of the edit position to the feature portion. An example of a function for setting an edit position to a position will be described. The following processing starts from the state shown in FIG. 14 described in the fourth embodiment.
It is assumed that the user instructs the movement of the editing position to the open end twice in a predetermined operation with respect to the circuit diagram of FIG. Specifically, for example, the instruction is performed by continuously pressing the TAB key twice, but other key operations or mouse operations may be performed.

FIG. 20 is a flowchart showing the process of moving the mouse cursor to the open end. Each process will be described below.
(Step ST301) The editing position management unit 4 waits for a movement instruction from the input unit 1.
(Step ST302) When the editing position management unit 4 receives a movement instruction, it determines whether it is the first instruction. If it is the first time, the process proceeds to step ST303, and if it is the second time or later, the process proceeds to step ST312.
(Step ST <b> 303) The editing position management unit 4 requests information on all open ends from the feature part detection unit 3.
(Steps ST304, ST305, ST306) The characteristic part detection unit 3 acquires network data from the editing data management unit 2, and the connection destination identifier is an open end from the network data (that is, the connection destination identifier is The circuit component data indicating "0") is searched, and the circuit component data of all the corresponding circuit components (that is, the circuit component ADD of ID3 and the circuit component SUB of ID5) are stored in the editing position management unit 4. introduce. If there is no corresponding circuit component, the characteristic part detection unit 3 notifies the editing position management unit 4 that there is no open end.

(Step ST307) When the editing position management unit 4 receives the circuit component data from the feature part detection unit 3, the editing position management unit 4 combines the coordinate information of the circuit component data and the connection destination list information of the circuit component data, and opens all open ends. (That is, the coordinates of ID3 circuit component ADD input 1 and input 2 and ID5 circuit component SUB output 1) are acquired, and the priority order is set in the order in which the open positions are located closer to the internal editing position information. (Ie, input 2 of ID3 circuit component ADD has the highest priority, then input 1 of ID3 circuit component ADD has the highest priority, and output 1 of ID5 circuit component SUB has the lowest priority) .

(Step ST308) At this time, since the instruction to move the edit position to the open end from the user is the first time, the edit position management unit 4 sets the internal edit position information to the open end coordinates having the highest priority. Is updated, the coordinates of the editing position are transmitted to the editing data management unit 2, and the open end list to which the priority is given as described above is held.
(Step ST309) When the editing position management unit 4 is notified from the feature part detection unit 3 that there is no open end, the editing position management unit 4 stops the editing position moving process.
(Step ST310) The edit data management unit 2 updates the internal edit position information to the coordinates of the edit position received from the edit position management unit 4, and instructs the display unit 9 to update the display.
(Step ST311) When the display unit 9 is instructed to update the display, the display unit 9 creates display data based on the coordinates of the editing position and the circuit diagram data obtained from the editing data management unit 2, and updates the display.

Subsequently, a second instruction is transmitted from the input unit 1 to the editing position management unit 4. The processing in the editing position management unit 4 that has received this second instruction is as follows.
(Steps ST312 and ST313) The internal editing position information is collated with the list of open ends with priorities held in step ST307. If an open end located at the same coordinate as the coordinate of the edit position at this time is present in the list of open ends with the above priority, it is determined whether the open end is given the lowest priority. If not, the process proceeds to step ST314. If the open end located at the same coordinate as the edit position coordinate at the time of receiving the second instruction does not exist in the list of open ends with priorities, the process proceeds to step ST309, where the edit position is set. Cancel the move process.
(Step ST314) The internal editing position information is updated to the coordinates of the open end of the rank that is one lower than the rank of the open end, and the coordinates of the edit position are transmitted to the edit data management unit 2.
(Step ST315) When the open end located at the same coordinate as the coordinate of the edit position at the time when the second instruction is received is given the lowest priority in the list of open ends with priorities, The internal editing position information is updated to the open end coordinates having a high priority, and the editing position coordinates are transmitted to the editing data management unit 2.
Thereafter, the process proceeds to step ST310, where the editing data management unit 2 updates the internal editing position information to the coordinates of the editing position received from the editing position management unit 4, and instructs the display unit 9 to update the display. In step ST311, when the display unit 9 is instructed to update the display, the display unit 9 creates display data based on the edit position coordinates and the circuit diagram data obtained from the edit data management unit 2, and updates the display. To do.
With the above processing, a circuit diagram in which the mouse cursor indicating the editing position is moved to the open end 75 is displayed.

In the fifth embodiment, since the user continuously performs a predetermined operation for moving the editing position to the open end, the open end existing in the edit data can be circulated. Since the open end can be easily set at the editing position, work efficiency in editing the circuit diagram can be improved.

In the fifth embodiment, the number of operation priorities may be displayed. Further, for example, the number of the current designation in the priority order may be displayed, such as 3/10 (the current designation indicates the third time out of the ten priority orders). Further, when the movement of the editing position is canceled during the circulation of the priority order (for example, when the ESC key is pressed), the editing position may be returned to the position of the first priority order.

As described above, according to the circuit diagram editing apparatus of the fifth embodiment, the editing position management unit performs the second and subsequent operations when the operation of moving the editing position to the feature part is continuously performed twice or more. Also for the operation, the position of the feature part in the order in which the operation of moving the edit position to the feature part has been lowered by the number of consecutive times in the priority order of the feature part determined based on the edit position at the time of the first operation Since the editing position is set to (i), all the movement position candidates of the editing position detected from the entire circuit diagram data can be easily visited. That is, according to the circuit diagram editing apparatus of the fifth embodiment, even when the operation of moving the editing position to the feature part is continuously performed twice or more, the editing position is alternately set to the position of the two specific feature parts. Since all the characteristic parts existing in the entire circuit diagram data can be circulated in order without continuing setting, the work efficiency in editing the circuit diagram can be further improved from the first embodiment.

Further, according to the circuit diagram editing apparatus of the fifth embodiment, since the priority order is determined in the order of the distance from the editing position to the feature part, it is troublesome to sequentially edit the vicinity of the editing position. Can be reduced and work efficiency can be improved.

Further, according to the circuit diagram editing apparatus of the fifth embodiment, the priority is set in the order of the proximity in the X-axis direction from the editing position to the feature part, or in the Y-axis direction from the editing position to the feature part. For example, in FBD (Function Block ia Diagram: function block diagram) etc., the arrangement of circuit elements and the connection of wiring are sequentially performed along the flow from input signal reading to output signal writing. However, it is possible to particularly reduce the number of editing operations when taking a typical editing order in such a case.

A case where the order of the open end from the editing position is set in order. However, also in the sixth embodiment, the characteristic part is not limited to the open end, and there are various candidates for the characteristic part as described in the first embodiment. The editing apparatus can be easily realized as in the first to fifth embodiments. In addition, as described in the fourth embodiment, there are various ways of determining the priority order to be given to the open end. In FIG. 22, an arrow 85 is a mouse cursor.

Hereinafter, by detecting a circuit element that can further add an input-side terminal among circuit elements existing in the circuit being edited, an open end that is an unconnected terminal is created by adding the input-side terminal to the circuit element.

This instruction is transmitted from the input unit 1 to the editing position management unit 4. Processing after the editing position management unit 4 receives this instruction is as follows.
(Process 1) The editing position management unit 4 requests the feature part detection unit 3 for information on the open end.
(Process 2) The characteristic part detection unit 3a collates the network data acquired from the edit data management unit 2 with the circuit element catalog acquired from the circuit element catalog management unit 5, and selects the input side from the network data. A circuit element to which a terminal can be further added is searched. As a result of the search, the circuit element (that is, the circuit element ADD) closest to the editing position acquired from the editing data management unit 2 is selected from the circuit components of the corresponding circuit element (that is, the circuit element ADD and the circuit element SUB). Next, one input side terminal is added to the selected circuit element, and the circuit component data of the circuit element is transmitted to the editing position management unit 4. When the corresponding circuit element does not exist, the characteristic part detection unit 3a notifies the editing position management unit 4 that there is no open end.
The subsequent processing is the same as the processing from step ST105 to step ST108 described in the first embodiment.
With the above processing, the position of the mouse cursor that is the editing position is moved to the open end created by adding the input side terminal to the circuit element that can further add the input side terminal with the circuit element existing in the edit data. Then, a circuit diagram as shown in FIG. 23 is displayed. In the drawing, a straight line 86 is an open end which is an added terminal on the input side.
