Abstract

The present application discloses a link, including: a first trace; a second trace; a via hole arranged between the first trace and the second trace; a first trace connected to both the first trace and the via hole A trace in the transition area; a trace in the second transition area connected to the second trace and the via; the trace in the first transition area and the trace in the second transition area are preset to improve the continuity of the link impedance Preset impedance value. It can be seen that the first transition area and the second transition area are arranged between the via hole and the first and second transition areas on both sides, and the first transition area and the second transition area are arranged between the first transition area and the second transition area. Also set the preset impedance value. By setting the optimal impedance value for the transition area routing, the impedance characteristics at the via hole can be changed, thereby optimizing the overall impedance value of the link. Therefore, there is no need to adjust the anti-pad , which can conveniently realize improving the continuity of link impedance and improving the quality of signal transmission. The present application also provides a server, which can also solve the above technical problems.

Description

technical field

[0001] The present invention relates to the technical field of servers, and more specifically, to a link and a server. Background technique

[0002] With the continuous development of computer technology, among many factors that determine system performance, the phenomenon of high-speed interconnection is playing a leading role. In high-speed link design, in order to avoid some unforeseen problems, it is necessary to optimize each module as much as possible.

[0003] In the design process of high-speed signal links in server systems, the optimal design of link impedance is particularly important. If the link impedances cross continuously, it will cause signal reflection, increase link loss, and then affect the quality of signal transmission, and even lead to design failure.

[0004] In link design, vias are an important factor affecting the continuity of link impedance. Under high frequency conditions, vias will show parasitic capacitance and parasitic induc...
