Modeling and analysis of single event crosstalk in multi-lines system

Abstract

With device feature size scaling down, single event crosstalk (SEC) effects should be considered carefully in the early design stages of circuits applied for space and ground radiation environments. A model for predicting SEC in 3-lines system is proposed based on the point admittance and the distribution network of the lines. By using the presented model, 1000 random generated circuits are modeled and tested. The simulation results show that the model has average error 5.52%, whose results match SPICE very well. The relevance between the parameters of the lines and the prediction accuracy of the model is analyzed by using grey theory.
