Processing method of electric information in CAD system, processing device of electric information in CAD system, program and computer-readable storage medium

摘要

Designing operation efficiency is improved by automatically transmitting and receiving circuit-related information and layout-related information required for designing each printed board between printed boards, for designing a plurality of printed boards at the same time. In an electric information processing method in a CAD system, the printed boards are designed at the same time by transmitting and receiving the circuit design information relating to the printed boards and the layout design information relating to the printed boards between the circuits and layouts relating to the printed boards.

主权项

1. A processing method of electric information in a CAD system, comprising:
a first displaying step of displaying the symbolic figure of a circuit part that a user selected as circuit part information being theoretical information that constitutes circuits relating to a plurality of printed circuit boards on a first window on a display screen, out of circuit part information stored in a circuit part library; a second displaying step of displaying circuit part connection lines connecting between the circuit parts inputted by the user on the first window; a third displaying step of displaying figures that express a plurality of board shapes inputted by the user as board shape information being physical information that constitutes layouts relating to the plurality of printed circuit boards side by side on a second window on the display screen; a display controlling step of, when an arranging operation of the symbolic figure of the circuit part displayed on the first window onto a figure that expresses the board shape displayed on the second window by drag-and-drop, performing control of displaying a two-dimensional actual size figure or a three-dimensional actual size figure being physical information for each of the circuit parts and wiring figures expressing the circuit board connection lines on the figure that expresses the board shape; a first accumulating step of, when the symbolic figure of the circuit part is displayed on the first window, accumulating information about the circuit parts and the circuit part connection lines displayed on the first window in database as the first list; a second accumulating step of, when the two-dimensional actual size figure or the three-dimensional actual size figure expressing the substrate shape is displayed on the second window, accumulating information about the substrate displayed on the second window as the two-dimensional actual size figure or the three-dimensional actual size figure in the database as the second list; a third accumulating step of calculating the occupied area of the circuit part arranged on the figure expressing the substrate shape, which is displayed on the second window, and accumulating the occupied area in the database; a fourth accumulating step of calculating the occupied area of wiring figures expressing the circuit part connection lines and accumulating the occupied area of the wiring figures in the database; a fifth accumulating step of calculating the sum of the occupied area of the circuit part and the occupied area of the wiring figures as a substrate area, and accumulating the sum in the database; and a changing step of changing the size of the figure expressing the substrate shape based on the substrate area.
