Problems solved by technology

[0005] When the differences between the links of different topologies are too large, no matter which set of parameters is used, the signals in all cases cannot meet the requirements. At this time, the redriver parameters can only be manually refreshed according to the link characteristics, which will cause great inconvenience to users. Reduced ease of operation of the product

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] In a link system with a redriver, the redriver parameters need to be set according to the link characteristics. Different link losses, impedance continuity, etc. need to set different parameters to optimize the signal characteristics. The core idea of ​​the present invention is: first, store multiple groups of redriver parameters in the system based on link characteristics, and then the system automatically sets the corresponding optimal parameters in the redriver according to different topological structures, effectively ensuring the quality of signal transmission and avoiding When the difference in link characteristics is too large, the redriver parameters cannot be shared, which improves user opera...

Abstract

The invention discloses a method for adaptively improving signal quality based on a redriver parameter. The method comprises the steps of finding a best redriver parameter of each link and storing theparameter in a system; after the system is cascaded, judging a connected link of a signal source; and setting a parameter of a redriver chip as a redriver parameter corresponding to the connected link. According to the method, it is ensured that the chip can perform redriver parameter optimization selection according to a topology type, and the method optimizes the signal quality, reduces the risk of link design, avoids manual refresh operations by users according to different links and reduces unnecessary time and cost costs. The system design success rate is improved.

Description

technical field [0001] The invention relates to the field of signal quality improvement methods, in particular to a method for adaptively improving signal quality based on redriver parameters. Background technique [0002] In traditional digital system design, high-speed interconnect phenomena are often negligible because they have little impact on system performance. However, with the continuous development of computer technology, high-speed interconnection is playing a leading role among many factors that determine system performance, which often leads to some unforeseen problems and greatly increases the complexity of system design. Therefore, in the design of high-speed links, it is necessary to optimize each module as much as possible, evaluate the design feasibility and risk points in advance with the help of simulation tools, and optimize the design based on the simulation results to improve the success rate of system design and shorten the development cycle. [0003...
