Position data processing method for EDA tool, electronic equipment and medium

Abstract

The invention relates to a position data processing method for an EDA (Electronic Design Automation) tool, electronic equipment and a medium. The method comprises the following steps: S1, acquiring arc data of a first design part in EDA design; s2, constructing a first vector, a second vector and a third vector; s3, determining a first ray, a second ray and a third ray, and dividing the interface into a plurality of areas; s4, obtaining coordinates of a to-be-measured point corresponding to a second design component in the EDA design, and constructing a fourth vector; s5, performing cross multiplication on the fourth vector and the first vector and / or the second vector and / or the third vector, and determining an area where the to-be-measured point is located; and S6, determining the position relationship between the to-be-measured point and the arc based on the area where the to-be-measured point is located, the distance between the to-be-measured point and the circle center and the radius corresponding to the arc, and further judging whether the position relationship between the first design component and the second design component accords with a design rule or not. According to the invention, the position data processing efficiency of the EDA tool is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a position data processing method, electronic device and medium for EDA tools. Background technique [0002] EDA (Electronic Design Automation) tools usually need to check and judge designs such as PCB (Printed CircuitBoard) design, package design, etc. EDA tools save these designs as graphic data, which may include trace (Trance) graphic data, copper skin (Shape) graphic data, pad (Padstack) graphic data, etc.; also includes non-electrical trace graphic data, such as 2D-Line graphic data, silk screen graphic data, etc. These graphic data often contain the shape of arcs. In the design process, it is usually necessary to judge the positional relationship between the coordinates of a certain point and the arc, or to calculate the minimum distance between the two, so as to determine whether the design violates the corresponding design rules. The traditional processi...
