Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] refer to figure 1 , figure 2 shown. A method for multi-channel high-speed cascading, including the following basic processes:

[0022] 1. Based on the mathematical formula of S-parameter topology extraction, the incident and reflection vector AB is used to represent the S-parameter model, and the relationship is simplified to B=SA

[0023] 2. Considering that different S parameters correspond to different impedances, use a diagonal matrix z with different impedance data 0 to represent current and voltage:

[0024] V = z 0 1 / 2 ( A + B )

[0025] I = z 0 -...

Abstract

The invention discloses a multichannel high-speed concatenation method. An S parameter result is obtained by solving a topology structure formed by concatenating multiple S parameter models. A set of port connection method is formulated, and an algorithm is designed: a matrix is utilized to express a topological relationship for multichannel concatenation; dependence of different S parameter models on the frequency domain is eliminated in a vector fitting manner. Therefore, the S parameter models are not required to be converted into other types of parameter models during connection with other components, and moreover, the innovative characteristics of supporting mixed connection of multiple S parameters and solving multiple S parameters at one time in a matrix manner are achieved. Compared with conventional loop simulation, the methods have the advantage that the analogue loop simulation performance and accuracy are greatly improved.

Description

technical field [0001] The invention relates to a multi-channel high-speed cascading method. Background technique [0002] S-parameters play a dominant role in microwave, analog loop simulation, and parametric model design. The traditional simulation circuit verifies and adjusts the model by changing the node voltage and branch current, which not only takes a lot of time, but also limits the scalability of the model. In the face of increasingly complex connectors, a more efficient multi-channel fast cascading method is required. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, provide a multi-channel high-speed cascading method, and find a method to find the topological relationship between the S-parameter model and other components in the analog loop simulation. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present inventi...
