Wiring design system and method

Abstract

The invention relates to a wiring design system which comprises a data processing device, wherein the data processing device comprises a calling module, a computing module and a judgment module. The calling module is used for calling a name and a thickness of each layer of a printed circuit board stored in a database; the computing module is used for computing actual length of a perforated residual section corresponding to each layer of the printed circuit board according to the name and the thickness of each layer of the printed circuit board, receiving the bit rate of transmitting a high-speed signal input by an input device and a relative permittivity of the printed circuit board, and computing the standard length of a perforated residual section of a high-speed signal wiring layer of the printed circuit board according to a preset formula; and the judgment module is used for comparing the standard length of the perforated residual section with the actual length of the perforated residual section of each layer to select the high-speed signal wiring layer. The invention also provides a wiring design method. The wiring design system and the wiring design system can automatically select the wiring layer for the transmission of the high-speed signal and ensure the transmission quality of the high-speed signal.

Description

technical field [0001] The invention relates to a wiring design system and a wiring design method, in particular to a wiring design system and a wiring design method suitable for selecting a wiring layer for high-speed signal transmission on a printed circuit board. Background technique [0002] With the high-density development of integrated circuits, the necessary information for circuit design also increases, and more and more electronic components and signal lines are required, and the wiring requirements for printed circuit boards are also getting higher and higher. When the high-speed signal is transmitted on the wiring of the printed circuit board, the resonance effect generated when the high-speed signal is transmitted through the through-hole stub of the printed circuit board will seriously affect the transmission quality of the high-speed signal. Therefore, how to select a suitable wiring layer for the transmission of high-speed signals to reduce the resonance effe...

Problems solved by technology

However, it takes a lot of time and energy to manually determine the wiring layer of high-speed signals, and it is extremely error-prone, and the job cannot be completed in a short time, so the efficiency is low
