Wiring method of circuit board

Abstract

A wiring method of a circuit board is mainly for detecting whether to surpass a wiring restricting area on the circuit board during high-speed wiring and determining whether a high-speed wire can surpass the wiring restricting area according to the set attribute information of the wiring restricting area; if not, performing wiring operation along the edge of the wiring restricting area so as to avoid the wiring restricting area. Thus, the wiring restricting area can be avoided automatically when the high-speed wire is distributed, thereby increasing the work efficiency.

Description

technical field [0001] The present invention relates to a circuit board wiring method, in more detail, relates to a high-speed line wiring method that can automatically avoid GAP (ground gap). Background technique [0002] In the process of circuit design, the high-speed line is an important signal line on the circuit board, and its speed and frequency are very fast. The designers of the circuit board often try to refer to the same plane as much as possible for the high-speed line. However, due to the unavoidable There is a GAP (referring to the gap between two pieces of copper foil, that is, the part without copper foil), so in the process of wiring, sometimes a high-speed line crosses the GAP, and when the high-speed line crosses the GAP, it will be affected differently. The influence of the plane layer leads to poor signal on the high-speed line, so the wiring engineer needs to use the naked eye to find the part where the high-speed line crosses the GAP. affect work effi...
