Abstract:

A signal integrity simulation method for high-speed backplane interconnection is proposed. The high-speed interconnector manufacturer provides only a parameter model, but by using the vector fitting method, the circuit model can be gained. The traces are analyzed by the partial equivalent element circuit (PEEC) method. A combination simulation method is derived, and the signal integrity simulation of the high-speed backplane interconnection is realized. The correctness of the equivalent circuit is verified by comparing the simulation result to the original parameter provided by the manufacturer, and the PEEC simulation results to the commercial software simulation results. Finally, a complete high-speed backplane interconnection channel is simulated, the correctness of the results is verified by comparing with those obtained from the commercial software. The analysis results of the eye diagram with the channel are given.
