Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0030] As we all know, when the signal is transmitted on the signal line, there will be a delay. If the transmission distance of a single-ended signal is long, the delay will be large. The difference between two signals (such as a differential signal or a data signal and a clock signal) There is a relative delay between them, which is equivalent to a phase shift of one of the signals, and the signal received by the receiving end will be distorted to a certain extent. If the distortion range is too large, there may...

Abstract

The invention discloses a high-speed signal equal-length control algorithm, a PCB (Printed Circuit Board) wiring method and a PCB. The high-speed signal equal-length control algorithm comprises the following steps that: on the basis of a preset 10-degree principle, according to a signal transmission period and a click period, determining equal-length tolerance to meet a system time sequence requirement; and through a ratio of the equal-length tolerance and a signal time delay rate, obtaining a high-speed signal equal-length control range. By use of the embodiment of the invention, on the basis of the preset 10-degree principle, the high-speed signal equal-length control range is calculated, a design principle and an algorithm with theoretical support can be provided for traditional high-speed circuit PCB design for carrying out key signal equal-length processing so as to be simple and practical, and the working efficiency of PCB design engineers can be greatly improved while the system time sequence requirement is met.

Description

technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a high-speed signal equal-length control algorithm, a PCB wiring method, and the PCB. Background technique [0002] With the rapid development of electronic technology, the integration technology of electronic transistors is growing exponentially according to Moore's law. As the frequency of electronic signals is getting faster and faster, the edges of signals are getting steeper, and the wavelength of signals is getting shorter and shorter, resulting in the time control of signal reception and transmission at the picosecond (ps) level, so printed circuit boards ( The distribution parameters of Printed CircuitBoard (PCB) cannot be ignored, and the time difference control of signal transmission and reception is becoming more and more important. [0003] At present, high-speed circuit design and signal integrity analysis are just emerging industri...
