Abstract

PURPOSE:To shorten the time for registering and collating connection data by composing the connection data of grouped signal name data and parts terminal group data. CONSTITUTION:An operator simultaneously designates bus lines corresponding to the least significant signal name data of the bus line and the most significant signal name data by utilizing data input means 5. Then, the data are defined as grouped signal name data 6, and the connection between parts and the bus lines is simultaneously designated by the parts terminal number data connected to the least significant signal line of the bus line and the parts terminal number data connected to the most significant signal line. Further, those data are defined as the parts terminal group data, defined as the connection data together with the grouped signal name data 6 and stored in a connection data storage means 1. According to the instruction of the operator, a data output means 11 reads single connection data 10 from the connection data storage means 1, outputs these data to an output medium such as a floppy disk or a communication circuit and applies them to a wiring pattern designing device.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic circuit design apparatus, and more particularly to a means for creating and storing connection data between terminals of parts.

[0002]

2. Description of the Related Art In a conventional electronic circuit designing apparatus, as shown in FIG. 3, wiring data 2 of component terminals stored in wiring data storage means 1 is a combination of component terminal number data 3 and signal name data 4. Was composed of. This data has been input by the operator using the data input means. Connection data 2 is signal name data 4 and component terminal number data 3
In some cases, the signal name data 4 and all the component terminal number data and 3 connected to the signal name data 4 are stored as a group.

Further, the connection data 2 in these formats are input to the wiring pattern designing device by using the data output means 11, and the electronic circuit design and the wiring pattern design are associated with each other. In particular, in the process of designing a wiring pattern, it has often been practiced to check the connection data by repeatedly correcting the circuit by comparing it with the circuit diagram.

[0004]

In this conventional electronic circuit designing apparatus, in the case of a circuit in which a plurality of components are connected to the bus line, the connection data 2 of the same number as all the terminals of all the components connected to the bus line are used. Exists. Alternatively, the connection data 2 that requires the data amount of the number of terminals of all the components connected to one bus line is present by the number of lines of the bus.

Therefore, it is necessary to register a large amount of data corresponding to the number of component terminals of all components connected to each bus line, which requires a great deal of time.

Further, there is a drawback that it takes a lot of time for the designer to check the connection data 2 and the circuit diagram.

An object of the present invention is to provide an electronic circuit designing device for registering connection data and collating circuit diagrams with connection data in a short time.

[0008]

In order to achieve the above object, an electronic circuit designing apparatus according to the present invention is an electronic circuit designing apparatus having a data inputting means in a connection data storage section, wherein the data inputting means is a bus. Signal name data for each group that collectively designates bus lines by the signal name data at the lowest level of the line and the signal name data at the highest level, and component terminal group data that collectively designates the component terminal numbers connected to the bus lines To create and.

Further, it has a connection data conversion means for converting the single connection data to the component terminal group data.

[0010]

The connection data is composed of group-specific signal name data and component terminal group data. In this way, the connection data is for each group, not for each individual part,
The processing time can be shortened.

The present invention will be described below with reference to the drawings.

(First Embodiment) FIG. 1 is a block diagram showing a first embodiment of the present invention.

In FIG. 1, in the electronic circuit designing apparatus of the present invention, the operator uses the data input means 5 to allow the operator to use the lowest signal name data 4 and the highest signal name data 4 of the bus line.
Use to specify bus lines at once. Then, it is set as the signal name data 6 for each group, and the component and the bus line are identified by the component terminal number data 3 connected to the lowest signal line of the bus line and the component terminal number data 3 connected to the highest signal line. Let's specify all the connections in batch. Further, the data is stored in the connection data storage means 1 as connection data together with the component terminal group data 7 and the group-specific signal name data 6.

Further, the data display means 8 reads the connection data 2 from the connection data storage means 1 and displays a data list for the operator to confirm and correct the data.

After that, the connection data conversion means 9 reads the connection data 2 from the connection data storage means 1 and all the signal name data between the lowest signal name data 4 and the highest signal name data 4 of the bus line. 4 is created, all the component terminal number data 3 to be connected to the bus line are created, and the single unit formation data 10 of the combination of the component terminal number data 3 and the signal name data 4 is created.

The data output means 11 reads the single connection data 10 from the connection data storage means 1 in accordance with an operator's instruction, outputs this to an output medium such as a floppy disk or a communication circuit, and gives it to the wiring pattern designing device.

According to this embodiment, a bus line consisting of 16 or 32 signal lines can be described by several pieces of connection data 2, and the registration time of the connection data 2 of the bus line can be greatly reduced.

(Second Embodiment) FIG. 2 is a block diagram showing a second embodiment of the present invention.

In FIG. 2, in the electronic circuit designing apparatus of the present invention, the operator uses the data input means 5 to output the terminal number data 3 and the signal name data 4 of the component from the conventional electronic circuit designing apparatus or the wiring pattern designing apparatus. The single connection data 10 of the combination is input.

Further, the operator uses the data input means 5 to input the group-specific signal name data 6 for collectively designating the bus lines to the designer, and stores this in the connection data storage means 1.

On the other hand, the connection data conversion means 9 compares the single connection data 10 with the group-specific signal name data 6 to form the component terminal group data 7, and stores this in the connection data storage means 1.

The data display means 8 also displays the component terminal group data 7 for the operator to confirm.

The data input means 5 also corrects the component terminal group data 7 which collectively designates component terminals to be connected to the bus line in accordance with a command from the operator.

Further, the connection data conversion means 9 creates single connection data 10 from the component terminal number data 7 and stores it in the connection data storage means 1.
