Problems solved by technology

The calculation process of the distance between the lines is complicated and the amount of calculation is large. The calculation results not only affect the electromagnetic interference between the lines, but also affect the electromagnetic interference of other electronic components on the printed circuit board, which in turn affects the quality of the entire printed circuit board product.

Embodiment Construction

[0014] Such as figure 1 Shown is the hardware architecture diagram of the wiring distance verification system of the printed circuit board of the present invention. The system includes a computer 10 , a database 11 and a connection 12 . Wherein computer 10, it comprises a plurality of software function units, is used for carrying out the calculation and verification of the shortest distance between lines (net) in the printed circuit board wiring process; database 11, is used for storing all net related information in the printed circuit board, including A line id (net id), all line segments (net segment) on each line, each line segment id (segment id), the basic rectangle of each line segment (segment selectbox), each line segment type (segment type) and other information. The net id is used to identify the net; the net segment is used to indicate the segment contained on the net; the segment id is used to identify the segment; the segment selectbox is used to determine a min...

Abstract

A verification system of wiring distance on printed circuit board comprises a databank and a computer including receiving module for receiving all sections of one line and placing them in set, a selection module for selecting a line section from set, a setting module for searching distance, an area confirming module for confirming rectangular area, a searching module for searching line sections inrectangular area, a calculating module for calculating out distance between lines, a comparing module for obtaining the shortest distance and judging module for judging whether all lines are verified.

Description

【Technical field】 [0001] The invention relates to a distance verification system and method, in particular to a distance verification system and method for printed circuit board wiring. 【Background technique】 [0002] As consumers have higher and higher requirements for electronic products, the integration of electronic components mounted on printed circuit boards (Printed Circuit Board) is also getting higher and higher. When electronic components are working, electromagnetic waves will be generated to interfere with the operation of other nearby electronic components, which is called electromagnetic interference. As the integration of electronic components is getting higher and higher and their functions are increasing, the operating speed of electronic components is also getting faster and faster, and the operating frequency is also getting higher and higher, which makes the intensity of electromagnetic waves stronger and causes electromagnetic interference between electr...
