Description

  The present invention relates to a wiring diagram design system for designing a wiring diagram of a substrate or the like.

  In recent years, in designing a wiring diagram of a substrate or the like, a circuit to be designed tends to be large. Therefore, it is difficult to design a large-scale circuit with a short delivery time by the conventional design method in which wiring design of a circuit on one board is consistently performed by one designer. From such a background, there exists a design system in which a plurality of designers cooperate to design one wiring diagram by using a plurality of design apparatuses connected to a network.

In this system, after the circuit diagram that is the basis of the design of the wiring diagram is captured and stored in each design device, the designer confirms the same circuit diagram displayed on the screen of the design device assigned to each designer. Then, for each design area decided between the designers, the component arrangement and the connection pattern are designed and a wiring diagram is created.
JP 2004-54642 A

  In the above system, each designer often works by looking only at the screen displayed on his / her design device, and performs the design with reference to the circuit diagram in which the other design sharing areas are mixed. Therefore, when a circuit diagram is complicated and large-scale, it may be difficult to accurately grasp its own design assignment on the circuit diagram at a glance. For this reason, duplicate design is performed by stepping into the design area of another designer, and a design mistake occurs in order to correct the overlap, resulting in a delay in delivery date.

  In order to solve the above-described problems, in the invention of the present application, in the wiring diagram design system in which a plurality of design devices are connected via a communication network, and the design device designs a wiring diagram from one circuit diagram, the circuit Boundary detecting means for detecting a boundary for dividing the figure and circuit diagram dividing means for dividing the circuit diagram based on the boundary are provided.

  With the above-mentioned configuration, designers can easily grasp the design area of their share with their own design devices, and designers do not face each other and design independently without being overwhelmed by adjustment work more than necessary. You can collaborate while doing. In addition, unnecessary design is not performed on the design area in charge of other designers during the design work, and as a result, the delivery time can be shortened.

  The best mode for carrying out the present invention will be described below. In the best mode for carrying out the present invention, in a wiring diagram design system in which a plurality of design devices are connected via a communication network and a wiring diagram is designed from one circuit diagram in the design device, the circuit diagram is Boundary detecting means for detecting a boundary for dividing and circuit diagram dividing means for dividing the circuit diagram based on the boundary are provided. With these configurations, the circuit diagram is divided and displayed on each design apparatus. It is a thing. The boundary detection means of this configuration allocates a design area using functional blocks on the circuit diagram when detecting the boundary position.

(Constitution)
Next, the configuration of the best mode for carrying out the present invention will be described. FIG. 1 is a diagram illustrating a wiring diagram design system according to a first embodiment. Reference numeral 1 denotes a design apparatus in which a first designer who also serves as a design manager performs wiring diagram design work toward an attached display screen. Reference numerals 2-1 to 2-N denote design apparatuses in which a designer different from the first designer performs a wiring diagram design work. The design apparatuses 1 and 2-1 to 2-N are connected to be communicable with each other via a communication network.

  FIG. 2 is a configuration diagram of the design apparatus 1 and 2-1 to 2-N. Reference numerals 3 and 10 denote storage units composed of a memory or the like. Reference numerals 4 and 11 denote display units composed of an LCD or the like. Reference numerals 5 and 12 denote input units such as a keyboard. A boundary detection unit 6 is provided only in the design apparatus 1 and detects the position of the boundary when the circuit diagram is divided. A division processing unit 7 is provided only in the design apparatus 1 and divides the circuit diagram. Reference numerals 8 and 13 denote communication units. Reference numerals 9 and 14 are control units for controlling the above-described configuration.

(Operation)
The operation of the best mode for carrying out the present invention will be described below. During the operation of this system, the first designer who is also a design manager operates the design apparatus 1 and loads a circuit diagram from another design apparatus into his / her design apparatus 1 via the communication network (S1). When the capture of the circuit diagram is completed, a setting screen is displayed on the display unit of the design apparatus 1. The first designer inputs numerical values such as the number N of design devices used for the design work, the ID number of each design device, and the design sharing ratio of each device from the setting screen (S2).

  Subsequently, the boundary detection unit 6 starts detecting the boundary position to divide the circuit diagram into N design regions (S3). In this process, first, the boundary detection unit 6 reads out functional block arrangement information on the circuit diagram recorded in the storage unit 3 (S4). As information on this functional block, for example, if a certain block area is an area composed of an analog circuit, this is distinguished from the digital circuit area as one functional block, and the other digital circuit area is allocated as another functional block. (S5). FIG. 4 illustrates the concept of setting the boundary position on the circuit diagram in the function blocks F1 to F5 classified in units of attributes as described above. Based on the arrangement information, the allocation is made to the same functional block designers who have similar attributes and are more efficient if one designer designs them collectively. The distribution work is performed over the entire circuit diagram, and all functional blocks are grouped to assign the division to a plurality of designers. By the allocation, the boundary of the design area is adjusted to determine the coordinates of the boundary position (S6). When the circuit diagram is divided into N regions based on the specified boundary coordinates, the ratio of the area occupied by the region to the entire circuit diagram is obtained for each region as a design sharing ratio (S7), and the first design is performed in advance. It is compared with the design sharing ratio inputted by the person in step S2 and stored in the storage unit 3 (S8). As a result of the comparison, if it is within a predetermined range, the controller 9 instructs the division processor 7 to divide the circuit diagram based on the boundary, assuming that the obtained boundary position is appropriate. To do. Thereby, the division processing unit 7 divides the circuit diagram stored in the storage unit 3 to generate N divided circuit diagrams (S10). The control unit 9 adds data of each ID number of the design devices 2-1 to 2-N corresponding to each divided circuit diagram (S11), and then transmits the divided circuit diagram to each design device 2 through the communication unit 8. To N (S12). In the design devices 2-1 to 2-N, each communication unit 13 receives the data of the divided circuit diagram, and collates the ID number recorded in advance in each storage unit 10 with the ID number of the received divided circuit diagram. If they match, the divided circuit diagram is displayed on the display screen of each device. If the ID numbers do not match, the design apparatus 1 is notified that the divided circuit diagram assigned to itself is not sent correctly.

  Each designer performs a wiring diagram design operation by inputting data necessary for the design from the input unit 12 while viewing the divided circuit diagrams displayed on the display units 11 of the respective design apparatuses 1 and 2 to N. When the designer completes the design work, each designer inputs an instruction to the effect that the work has been completed from the input unit 12. Thus, the control unit 14 adds the ID number read from the storage unit 9 to the created wiring diagram, and then transmits the wiring diagram to the design apparatus 1 via the communication unit 13. When the design device 1 receives data of each wiring diagram of the design devices 2 to N (S13), the control unit 9 stores the ID number list of the design device stored in the storage unit 10 and the ID of the received wiring diagram. After matching the numbers and checking the ID (S14), when all N wiring diagrams are ready, they are sent to the design apparatus for wiring diagram combining processing (S15) to combine the wiring diagrams. . As a result, the wiring diagram is finally completed and the design work is completed.

In the above-described best mode for carrying out the present invention, the processing using the functional blocks of S5 to S9 in FIG. 3 is not limited to digital / analog, but is a specific example such as a power supply unit or a signal unit. You may classify by the unit of typical operation use.
Further, in the process using the function blocks S5 to S9 in FIG. 3, instead of the process, the number of end points serving as I / F contacts when the circuit diagram is divided is minimized. Alternatively, the boundary may be determined by searching the division position on the circuit diagram.
