Far-end crosstalk (FEXT) noise is one of the major issues that limits signal integrity performance for high-speed digital products. It important to estimate accurately avoid margin failure or overdesigned transmission lines. Traditionally, analytical formulas are based on lossless and perfect impedance match assumptions, which provide limited guidance a practical line design. A phenomenon observed lossy conductor increases FEXT coupled striplines. To reasonable explanation, numerical...

In this article, a novel training set optimization method in an artificial neural network (ANN) constructed for high bandwidth interconnects design is proposed based on rigorous probability analysis. general, the accuracy of ANN enhanced by increasing size. However, generating large sets inevitably time-consuming and resource-demanding, sometimes even impossible due to limited prototypes or measurement scenarios. Especially, when number channels required are huge such as graphics double data...
