Problems solved by technology
However, with the development of electronic equipment towards more and more complex and high-density direction, more and more electronic components are required, and the electronic components and signal lines that need to be arranged on the unit area of the printed circuit board are also becoming denser. , so that the adjustment of the line width parameters is very limited in space. At this time, it will be difficult to adjust the line width parameters to make the signal line meet the preset impedance requirements

The invention relates to a signal line adjustment method and a system thereof which are applied in layout software of a printed circuit board, wherein, the layout software presets a cross-section parameter and a maximum permissible linewidth parameter corresponding to the signal line, and the cross-section parameter is related to a linewidth parameter and a line thickness parameter of the signal line. The method mainly comprises the following steps: firstly, the signal line is selected on the printed circuit board so as to acquire the cross-section parameter of the signal line and an actual linewidth parameter and an actual line thickness parameter of the signal line; secondly, the actual linewidth parameter and the actual line thickness parameter which are acquired are received, and an actual cross-section parameter of the signal line is calculated according to preset operation processing rules; thirdly, comparison is made whether the actual cross-section parameter is equal to the preset cross-section parameter; if the actual cross-section parameter is unequal to the preset cross-section parameter, the linewidth parameter and the line thickness parameter of the signal line are adjusted according to the preset cross-section parameter and the operation processing rules, and then the actual cross-section parameter of the signal line is adjusted to be the preset cross-section parameter, thereby the signal line is made to meet an impedance requirement.
Description
technical field [0001] The present invention relates to a signal line adjustment technology, more specifically, to a signal line adjustment method and system applied in wiring software of printed circuit boards. Background technique [0002] Printed circuit boards appear in almost every electronic device, such as the motherboard of a computer device, or a display card, and so on. The printed circuit board is used to carry a plurality of electronic components required for the operation of each electronic device. Of course, in addition to carrying and fixing the electronic components, the main function of the printed circuit board is to provide a signal on the printed circuit board through signal lines. Therefore, the transmission quality of the signal line (especially the high-speed signal line) will affect the performance of the entire printed circuit board, and the transmission quality of the signal line is determined by the signal line In addition, the impedance of the si...
