Abstract

The invention discloses a simulation method, a simulation device and a simulation system for high speed signal channel via holes. The method comprises the following steps of: classifying the via holes according to type information and plate thickness information of a plate material; modeling the classified via holes and constructing an original via hole model library; performing simulation test verification on the original via hole model library and constructing a verified via hole model device library; and forming an actual via hole simulation model for simulation by using the via hole model device library. Compared with the prior art, the simulation method, the simulation device and the simulation system for the high speed signal channel via holes have the advantages that: the high speed signal channel via hole simulation efficiency is improved, the time of high speed signal passive channel simulation design is shortened, and the simulation accuracy is improved.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to a simulation method, device and system for via holes of high-speed signal channels. Background technique [0002] Today's telecommunication systems, data communication systems, and computer systems all rely on the transmission of high-speed serial data. Even the system rate reaches 6.25Gbps, and the backplane standard of 10Gbps Ethernet has also been developed as a part of the 802.3ap standard. In order to complete the design of the chip-to-chip high-speed signal path system on the entire backplane, complex simulation, design, and test verification processes are required. [0003] In a typical high-speed interconnection system, the signal is driven by the chip on the single board, passes through the single board, the connector backplane, the connector and another single board, and reaches the receiving end chip. The passive path in this system is the mai...
