当然、回路図改版時にはこの２種類の回路図情報を同時
に改版しなければならず処理効率上問題である。The conventional printed board mounting circuit design support system described above uses the circuit diagram input mechanism 11 for both the input of the printed board mounting circuit D1 and the input of the logic partial circuit D4.
The printed board mounted circuit D1 includes parts that are not used in the logic simulation, and conversely, the logic simulation circuit does not include the necessary parts in the printed board mounted circuit D1, or is replaced with other parts so that it is not a printed board mounted circuit. Since they are different, the circuit diagram input mechanism 11 must create and manage two types of circuit diagram information in the drawing information D14: printed board mounting information and logic simulation information.
Naturally, when revising the circuit diagram, these two types of circuit diagram information must be revised at the same time, which poses a problem in terms of processing efficiency.

果がある。As explained above, the present invention allows drawing information to be unified by limiting the circuit diagrams to be created and managed to printed circuit board mounted circuit diagrams, and when revising a circuit diagram, only the printed board mounted circuits need to be changed. Since the predetermined rules can be changed externally, there is an effect that a circuit mounted on a printed board can be automatically changed to an optimal logic simulation circuit.
