Signal wire regulation method and system

Abstract

The invention relates to a method and a system for adjusting signal wires, applied to wiring software of print circuit boards. Two signal wires to be changed are selected, the attribute data of the connective ports on the two ends of each signal wire is read, a first cutoff point is got from the tangent point of a circle fixed by a circle centre which is one connective port defined as a first connective port at the same end of the two single wires and a signal wire connected with the other connective port defined as a second connective port; the second connective port is used as a point outside the circle to generate a tangent which is tangent with the circle and intersect with a single wire connected with the first connective port, thus getting a second cutoff point; based on the first and second cutoff points, the line segments between the two ends and the cutoff lines are deleted, the connective ports are changed, and automatically connected to the line segments of the cutoff points of original signal wires, the wiring width of the signal wires is adjusted according to the attribute data of the changed connective ports, thus improving the adjusting efficiency of signal wire wiring sequence and the correction rate of wiring operation.

Description

technical field [0001] The present invention relates to a signal line adjustment technology, more specifically, to a signal line adjustment method and system for readjusting the layout sequence of two signal lines on the printed circuit board through wiring software. Background technique [0002] Generally, it is necessary to carry out wiring design on the printed circuit board so that the components on the printed circuit board are electrically connected and play corresponding functions. At present, electronic engineers usually use the layout of the printed circuit board (PCB) through such as Allegro, Protel and other wiring software programs are completed. However, in the actual wiring process, the order of the signal lines that have been laid may be unreasonable due to changes in the layout of components in the printed circuit board or other human factors. Adjust the components (such as pins or vias) connected to each of the signal lines. [0003] When the above situati...

Problems solved by technology

However, using the above-mentioned signal line adjustment method, the wiring operator needs to sequentially select both ends of the signal line and repeatedly perform a series of operations such as "cut-off-connection", which is not only cumbersome to operate, but also, especially when the signal line is very For a long time, the wiring operator needs to slide the mouse back and forth to repeatedly perform the above operation steps at both ends of each signal line. In this way, the workload of wiring and the time spent on wiring will undoubtedly be greatly increased, which will affect the efficiency of wiring and cause errors easily. Routing Results
