Problems solved by technology

Since the main board traces are relatively long, it is difficult to accurately locate the trace space by manually creating equal-angle polylines, which will take up more space; manually creating traces is inefficient; and it is difficult to ensure that the length of each polyline is consistent, which affects Signal Transmission Quality

Abstract

The invention provides a method and device for changing a straight line into a broken line at any angle in PCB design, and the method comprises the following steps: selecting a straight line to be changed into a broken line, and obtaining the starting point coordinate, end point coordinate and length of the straight line; inputting and obtaining a preset bending angle and the length of a bending line segment, and according to the starting point coordinate, the terminal point coordinate, the straight line length, the bending angle and the length of the bending line segment, solving the coordinate of a projection point of each bending point on the straight line based on a definite proportion score formula; according to the starting point coordinate, the coordinate of the first projection point on the straight line and the bending angle, solving the coordinate of the first bending point based on a vector method; according to the coordinate of the first bending point and the coordinate ofthe projection point of each bending point on the straight line, reversely solving the coordinates of the rest bending points in sequence based on a definite proportion score formula; and sequentiallyconnecting the bending points according to the coordinates of the bending points so as to draw corresponding broken lines. The method can automatically change the straight line segment into the broken line so as to guarantee the design quality.

Description

technical field [0001] The present invention relates to the field of PCB (Printed Circuit Board, printed circuit board) design, and more particularly, relates to a method and device for changing straight lines into arbitrary angled lines in PCB design. Background technique [0002] There are many kinds of PCB design software on the market. Cadence is the most widely used software in the industry, not only because it has powerful functions and a variety of related software as support, but also because it provides an open secondary development interface and relatively complete The development language library, users can carry out secondary development according to their own needs. Skill language is a high-level programming language based on C language and LISP language built into Cadence software. Cadence provides a wealth of interactive functions for Skill language. Researching Skill language and then writing tools can greatly improve work efficiency. [0003] In the design ...
