Abstract

The invention discloses a detecting method of object position applied in circuit layout, which comprises capturing the coordinate range of the word objects of the circuit layout, then capturing the coordinate range of a to-be-compared object of the circuit layout, then detecting whether the coordinate range of the word objects superposes with the coordinate range of the to-be-compared object or the distance between both is smaller than the preset value. The method improves the human detecting mode adopted former, thereby shortening the detecting time of the layout, further increasing the quality of printed circuit boards.

Description

technical field

[0001] The invention relates to a detection method of a circuit layout diagram, in particular to a detection method of an object position. Background technique

[0002] Generally speaking, when developing a circuit board, first, an electronic engineer draws a circuit diagram (Schematic) according to customer requirements. Afterwards, the layout engineer designs the circuit layout according to the circuit diagram, so as to manufacture a printed circuit board (PCB) according to the circuit layout.

[0003] In order to improve the quality of the printed circuit board, the layout engineer must inspect the circuit layout after completing the circuit layout. For example, if the position of the text object overlaps with the through hole (Via), the text will be damaged during the drilling process in the process of making the circuit board, and the engineer will not be able to correctly interpret the text content.

[0004] In view of this, in the prior art, layout e...
