Electrification modeling method for the cable network of electronic system

To transform the structural model of electronic system cable networks into an electrification model that can be used for electromagnetic simulation, a layered structure modeling method based on the connection table is proposed. This method divides a cable network into five levels: cable harness, cable harness branch, cable, signal, and signal port. The electrification of each layer is definite by transforming the information in the connection table and the original structural model or adding some necessary material parameters and data. In this paper, a common connection table is used as an example. The electrification model of this cable harness is implemented in the computer-aided engineering software, and crosstalk simulation is performed. The simulation results can correctly represent the electrical characteristics of this cable harness, which shows that the proposed method is accurate, and the electrification model can be used for the electromagnetic simulation of the cable network.
