Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a design support system for creating circuit diagrams.

[Conventional technology]

Conventional design support systems for creating circuit diagrams print from drawing information input using a circuit diagram input mechanism that inputs printed circuit board mounted circuits and logic subcircuits, a test button input mechanism, and a circuit diagram input mechanism. A printed circuit board mounting information extractor that extracts board mounting information, and a logic simulation mechanism that performs logic simulation using drawing information input using a circuit diagram input mechanism and test button information input using a test button input mechanism. It consisted of

[Problem to be solved by the invention]

The conventional design support system for creating circuit diagrams described above is configured so that the circuit diagram input mechanism can be used both for inputting printed circuit board mounted circuits and for inputting logic subcircuits for logic simulation. Because the circuit has parts that do not exist in the logic simulation or are replaced with other parts and is different from a circuit mounted on a printed board, two types of circuit diagrams are created and managed: a circuit mounted on a printed board and a circuit for logic simulation. Another disadvantage is that when revising the circuit diagram, two types of circuit diagrams, the printed circuit board mounted circuit and the logic subcircuit, must be revised.

[Means to solve the problem]

The design support system for creating a circuit diagram of the present invention stores logic circuit diagram information created by inputting data for creating a logic circuit diagram in a first drawing information storage unit using a first data input/output device. a logic simulation circuit that extracts logic simulation information based on predetermined logic symbols from the first drawing information storage unit, creates logic simulation circuit information, and stores the logic simulation circuit information in the logic simulation information storage unit; information creating means; and a second device that creates printed circuit board mounting circuit diagram information according to predetermined rules based on the logic circuit diagram information from the first drawing information storage unit and stores it in a second diagram information storage unit. and a rule changing means for changing the predetermined rules by inputting data from a second data input/output device.

U21.

Next, the operation of this embodiment will be explained.

First, the creation of drawing information of a logic circuit diagram and its logic simulation information will be explained.

Data for creating a logic circuit diagram input using the display 17 and a mouse/keyboard is sequentially stored in the drawing information memory 131 through processing by the CPU II.
I stores the completed logic circuit diagram information in the drawing information memory 131.
, and store it in the drawing information data file 151.
Next, CPtJll extracts logic simulation information using predetermined logic symbols from the logic circuit diagram information read from the drawing information memory 131 and stores it in the logic simulation information file 152.

Next, creation of printed board mounting information will be explained.

First, the drawing information data file 151 in the auxiliary storage device 15 of 5A100 is taken out and set as the drawing information data file 251 in the auxiliary storage device 25 of 5B200. It is also assumed that the user specified rule file 252 has already been set.

When a command to create printed board mounting information is input from the terminal 27, the CPU 21 loads the drawing information data file 251 and the user specified rule file 2 from the auxiliary storage device 25.
52 information in the drawing information data file 23 of the storage unit 23
1 and the user-specified rule file 232.

Next, the CPU 21 processes the logic circuit diagram information from the drawing information data file 231 according to the user-specified rules from the user-specified rule file 232 and the general rules from the default rule file 233 to create printed board mounting information and file 253.

Note that if there is a change in the user-specified rule, data on the changed rule is input in advance from the terminal 27. The input change rule data is used to update the user specified rule file 232 by the CPU 21. The updated rules are finally read from user-specified rule file 232 and stored in user-specified rule file 252.

〔Effect of the invention〕

As explained above, the present invention provides a first data input/output device that stores logic circuit diagram information created by inputting data for creating a logic circuit diagram in a first drawing information storage unit.
and a logic simulation information generator for extracting logic simulation information based on predetermined logic symbols from a first drawing information storage unit to create logic simulation circuit information and storing the logic simulation circuit information in the logic simulation information storage unit. and second drawing information that creates printed circuit board mounting circuit diagram information according to predetermined rules based on the logic circuit diagram information from the first drawing information storage unit and stores it in the second drawing information storage unit. By having the creation means and the rule change means for changing the predetermined rules by data input from the second data input/output device, the circuit diagrams to be created and managed can be limited to only logical circuit diagrams. This has the effect that circuit diagram information can be unified, and only the information on the logic circuit diagram needs to be changed when revising the circuit diagram. Also, you can change the predetermined rules, so
This has the effect of automatically changing a logic circuit diagram to an optimal printed circuit board mounting circuit diagram.
