| Abstract: | Aiming at proper application of IBIS model,quickly verifying the accuracy of IBIS model and the simulation program of IBIS model in signal integrity analysis were presented.Firstly,an implicit connection between the data of model was introduced,in order to quickly verify the accuracy of IBIS model;secondly,based on IBIS model,signal integrity simulation and analysis of optic fiber temperature measure system were discussed.After extracting output impedance from IBIS model,the reflection simulation was carried out,and then,under the same line width,the crosstalk simulation was executed at different signal distances,in order to ensure the safety of signal distance.The results indicate that the information extracted from the IBIS model and the result of simulation can satisfy signal quality requirements in high-speed digital circuit design. |
