System for switching laying bedding plane of signal line

Abstract

The invention provides a signal wire layout plane switch system, which is carried on a computer unit having printed circuit board circuit diagram layout software and is used for switching signal wireslaid out in the first plane of a printed circuit board onto the second plane of the printed circuit board. At least the type information of the signal wires to be laid out, and the width informationof the signal wires in the first plane and the second plane are defined in the circuit diagram layout software. The type information of the signal wires selected from the first plane of the printed circuit board currently displayed by the printed circuit board diagram layout software is acquired from the software so that when the printed circuit board diagram layout software is switched to the second plane from the first plane of the printed circuit board currently displayed, the selected signal wires are displayed on the second plane; the width of the signal wires laid out on the second planeis changed according to the width information of the signal wires on the second plane acquired by the circuit diagram layout software.

Description

technical field [0001] The present invention relates to a signal line layout level switching system, in particular to a signal line layout level switching system carried in a computer device with printed circuit board (PCB) circuit board pattern layout software. Background technique [0002] With the development of high-density integrated circuits, there is a need to use electronic design automation (Electronic Design Automation: EDA) software for wiring. At present, the more common wiring method is the combination of automatic wiring and manual wiring. The two wiring methods have their own characteristics. Compared with manual wiring, automatic wiring has the characteristics of fast completion speed and high accuracy, and can quickly respond to market demand for products. Design requirements, while manual wiring can make adjustments to partial wiring methods that do not meet the design, so as to improve the efficiency of wiring. [0003] Just because the function of the au...

Problems solved by technology

It can be seen from this that the switching operation of many signal lines through the Allegro software will require repeated setting steps, so not only the processing is cumbersome and inconvenient, but also prone to errors

[0004] For this reason, the current general signal line switching method is to first delete the original circuit line manually, and then manually draw in the target circuit layer, and abandon the layer signal line switching function provided by Allegro software, but, as mentioned above , the speed of manual wiring is slow, and the operation of deleting and redrawing signal lines will greatly increase the workload, resulting in a decrease in efficiency; therefore, although manual work is more convenient than the interlayer function of signal lines in Allegro software, but in In the case of a large workload, it is difficult to avoid the occurrence of errors

[0005] Therefore, due to the inherent functional defects of the software, it is necessary to use manual line-changing operations to carry out repeated work. is an urgent problem to be solved
