[Industrial Application Field] The present invention is a CA system that creates a circuit diagram using a different type of element symbol than the element symbol used by CAD.
Regarding improvement of D.

In recent years, engineering workstations (hereinafter referred to as EWS)
Due to the development of CAD? Various types of E
WS is out.

The structure of an example of an EWS with CAD is shown in Fig. 8, with a processor 20, a graphic display 2
1. A memory 22 that has a circuit diagram editing program (circuit diagram editing system), an automatic placement automatic wiring program, etc., an external memory 23 that stores various data, and a keyboard 24.
, a coordinate input device 25, etc., and when creating a circuit diagram, the circuit diagram designer uses the graphic display 2l in the circuit diagram editing system to consider the circuit operation, We have created an easy-to-understand circuit diagram as shown in A).

However, these EWS CAr) element symbols use, for example, MII, standards, JIS inkstone, etc., and the shapes and wiring terminal positions may differ, making it difficult to use EWS with different types of element symbols. In order to manually create a circuit diagram for use, it is necessary to create a circuit diagram by converting the element symbols.

Even if you try to convert the element symbols in the circuit diagram, it is not possible to convert them simply because the element symbols have different shapes and wiring terminal positions, but for example, as shown in Figure 7 (A),
It is desired that an easy-to-understand circuit diagram, as shown in FIG. 7(B), be created in such a way that the relative positions of the original circuit diagram and the element symbols do not overlap with each other.

[Prior Art] FIG. 9 is a block diagram showing the structure of the main parts of a conventional CAD.

Conventionally, in order to create a circuit diagram for different types of CAD using different types of element symbols, the external memory 23 shown in FIG.
As shown in the figure, a netlist data storage unit 10 that stores netlist data indicating element symbols and connections between element symbols, a different element symbol storage unit 2 that stores element symbols of different types of CAD, and a circuit for different types of CAD A diagram data storage section 9 is provided.

Then, the sales section 11 of the illegal list data storage section 11 reads the netlist data from the netlist data storage section 10 and stores it in the circuit diagram storage section 12.

On the other hand, the element symbol reading unit 7 reads the different element symbols from the different element symbol register 1 and key unit 2, and passes them to the automatic placement automatic wiring unit 13.

The automatic placement automatic wiring section 13 creates a circuit diagram using the netlist data stored in the circuit diagram storage section l2 and the different element symbols, stores it in the circuit diagram storage section 12, and converts it into a different type of CAD format in the conversion section 8. , converted to match the format of the different CAD, and stored in the circuit diagram data storage unit 9 for the different CAD.

Then, this stored circuit diagram data is passed to a different type of CAD.

(Problem to be Solved by the Invention) However, in the conventional method described above, in order to automatically arrange elements, circuit designers use a Glare ink display to make it easier to understand by considering circuit operation. There is a problem that the circuit diagram may be arranged differently from the original circuit diagram, resulting in a circuit diagram that is difficult to understand.

According to the present invention, when a circuit designer uses a graphic display to convert a circuit diagram that is made easy to understand by considering the circuit operation into a different element symbol, the relative position with respect to the original element symbol remains unchanged. The purpose is to provide CAD that can prevent element symbols from overlapping.

(Means for solving the problem) FIG. 1 is a block diagram of the principle of the present invention.

and, read out the circuit diagram data stored in the route diagram data storage unit l, create and store a circuit diagram, 1,000 step 3
Then, the element symbols of the circuit diagram created and stored in the circuit diagram creation or storage means 3 are read out from the element symbol storage unit 2 with different IFs, while the relative arrangement of the element symbols is such that the element symbols do not overlap. (・) An element symbol conversion rearrangement means 4 for converting into an element symbol, and a rewiring stage 5 for wiring 14 times so as to match the element symbol transformed and rearranged in the element symbol transformation rearrangement stage 4. The precepts are as follows.

(Function) According to the present invention, a circuit designer uses a graphic display to take the circuit operation into consideration and edit the data of the circuit diagram to make it easy to understand, using the CAD circuit diagram editing sosteno. The circuit diagram data is stored in the data storage section 1, different types of element symbols are stored in the element symbol storage section 2, and the circuit diagram data is read out from the circuit diagram data storage section 1 in the circuit diagram creation storage means 3. Draw or memorize a diagram.

On the other hand, the element symbol conversion and rearrangement means 4 reads different types of element symbols from the element symbol storage section 2, and converts the element symbols of the circuit diagram stored in the circuit diagram creation or storage stage 3 into
The relative arrangement of the element symbols is performed by converting them into different types of element symbols so that the element symbols do not overlap, and by the rewiring means 5, so that the converted element symbols are connected to the wiring terminal positions. Perform rewiring.

In other words, the circuit diagram that has been converted into a different type of element symbol and that has been created or stored in the storage means 3 is in the same relative position as the circuit diagram that has been edited to make it easier to understand considering the original circuit/GJJ creation. This is the circuit diagram.

[Embodiment] Fig. 2 is a block diagram showing the structure of the main part of Embodiment 1 of the present invention, Fig. 3 is a flowchart of a program for converting to a different type of CAD element symbol according to the embodiment of the present invention, and Fig. 4 The figure shows the flow of another element symbol movement program for securing replacement space according to an embodiment of the present invention, FIG. 5 is a diagram showing another element symbol movement after an example of element symbol conversion, and This figure is a diagram showing an example of element symbol rewiring, and FIG. 7 is a diagram showing a circuit diagram after conversion into a different type of CAD element symbol according to an embodiment of the present invention.

In the case of the present invention, as shown in FIG. 2, a circuit designer uses a CAD circuit diagram editing system to create a circuit+. The data of the circuit diagram edited to make it easier to understand after thinking about the work B is stored in the external memory 23 in Fig. 8.
In addition, different types of element symbols are stored in the different types of CAD element symbol storage unit 2 of the external memory 23 in FIG.

Then, the circuit diagram data reading unit 6 reads the circuit diagram data from the circuit diagram data storage unit 1 and creates the same circuit diagram or stores it in the storage unit 3.
Create and memorize the circuit diagram.

Further, the element symbol reading section 7 reads a different type of element symbol from the element symbol storage section 2 of the different type of CAD, and passes it to the element symbol conversion and relocation section 4.

In the element symbol conversion rearrangement section 4, the circuit diagram creation storage section 3
The element symbols of the circuit diagram stored in the circuit diagram are converted and arranged into different types of element symbols so that the element symbols do not overlap in the relative arrangement of the element symbols.

Next, the rewiring section 5 rewires the converted element symbols so that they match the wiring terminal positions.

Load a page of news.

In step 3, for example, if the element symbols for one page are as shown in FIG. 5(A), the lower left element symbol of the drawing is selected for processing.

In step 4, for example, in the case shown in FIG. 6(A), the wiring between the element symbols and the wiring from the intersection of the wiring to the element symbol are erased, as shown in FIG. 6(B).

In step 5, if the element symbol after conversion is large, the process proceeds to step 10, in which another element symbol is moved to secure the replaced space.

This point will be explained using FIGS. 4 and 5.

In step 1 of Fig. 4, when converting the element symbol A of Fig. 5(A) to the element symbol of Fig. 5(B), the gap with the adjacent element symbol in the Y-axis direction is set at a specified value. The value α
(If it is greater than or equal to α, proceed to step 6.) In step 2, the amount of movement β that becomes α is determined, and in step 3, the amount of movement β is moved.

Then, it becomes as shown in C of Fig. 5 CB). Next, in step 4, the element symbol C is made symmetrical, and if the gap between the element symbol and the adjacent element symbol in the Y-axis direction is smaller than a predetermined value α, the element symbol is moved again.・Element symbol so that the gap between and is α. However, in the case of FIG. 5, the value is greater than or equal to α, so it is not moved.

Next, in step 6, in the same manner in the X-axis direction, element symbols, 2, and E are manually moved until the gap becomes equal to or larger than α.

Then, after the movement, as shown in FIG. 5(B), the element symbols and relative arrangement of the original circuit diagram remain as they were, and the process proceeds to step 6 in FIG.

Next, return to step 5 in FIG. 3, and if the converted element symbol is not large, proceed to step 6, replace the element symbol with a different type of element symbol, and proceed to step 7, where the wiring terminal of the replaced element symbol Rewire to match the location.

This rewiring will be explained using FIG. 6.

When the element symbol is converted, FIG. 6(B) becomes as shown in FIG. 6(C), and as shown in FIG. 6(D), rewiring is performed to match the wiring terminal position of the element symbol.

Then, in step 8.9 of FIG. 3, select the processing symmetry from the lower left to the top and then to the right until the conversion of all element symbols for one true is completed, and perform steps 4 to 7 and step IO. I do.

If this operation is continued as shown in line 2 until all pages are completed in step 11, for example, if the circuit diagram before conversion is the one shown in FIG. 7(A), the element as shown in FIG. A circuit diagram with equal relative placement of symbols is obtained.

(Effects of the Invention) As described in detail above, according to the present invention, when a circuit designer uses a graphic display to convert a circuit diagram that is made easy to understand by considering the circuit operation into a different element symbol. , it is possible to create a circuit diagram in which the element symbols do not overlap in their relative positions with the original element symbols.
