Embodiment Construction

[0024] figure 1 A flow chart of a method for inspecting traces of a circuit layout according to an embodiment of the present invention is shown. figure 2 It is a schematic diagram of layout traces according to an embodiment of the present invention. Please merge reference figure 1 and figure 2 , first, in step S101, select one of the layout traces ( figure 2 Only the layout trace 200 is used as an example). Wherein the layout trace 200 has a plurality of line segments. In this embodiment, the layout trace 200 has, for example, line segments L1 , L2 and L3 , but the scope thereof is not limited. In addition, the above layout diagram may be a layout diagram of a printed circuit board (Printed Circuit Board, PCB).

[0025] In step S103, along the layout trace 200, select the first line segment and the second line segment of the above-mentioned line segment as the first comparison line and the second comparison line, wherein the first line segment has a first end point an...

Abstract

The invention discloses a method for checking trace of circuit layout. In a layout chart, layout trace is selected as check trace, wherein the layout trace comprises a plurality of segments; along the layout trace, a first segment and second segment in the segments are selected as a first comparison line and a second comparison line respectively, wherein the first segment contains a first end point and a second end point, the second segment contains a third end point and a fourth end point, the second end point and the third end point are connected to form a common end point; according to thecoordinate positions of the first end point, second end point and the common end point, whether the angle between the first comparison line and the second comparison line is not more than 90 degrees is judged to generate a judgment result; and if so, a prompt is generated.

Description

technical field [0001] The present invention relates to a method for inspecting traces of a circuit layout, and in particular relates to an inspection method for finding layout traces with right angles or acute angles in a circuit layout. Background technique [0002] After completing the circuit layout, various checks are usually performed. Trace inspection is one of many inspection items. Because layout engineers often accidentally leave traces with right angles (the angle between two line segments is 90 degrees) or acute angles (the angle between two line segments is less than 90 degrees) in the process of circuit layout . These right-angled or acute-angled traces are likely to produce a tip discharge effect when the physical printed circuit board is in operation. [0003] Generally speaking, to check traces with right angles or acute angles, layout engineers often have to manually check one trace by one trace. When a certain stitch is detected, it is manually judged ...
