IBIS仿真模型的应用

Application of IBIS Model

IBIS模型在高速PCB仿真设计中有广泛的应用。然而大多因缺乏对IBIS模型的深入认识而大大降低仿真的效率和正确性。本文通过深入分析IBIS模型的数据表和对应的波形曲线,得出IBIS模型在高速PCB仿真设计中的一些新的重要结论。这些新的结论揭示了基于IBIS模型的信号完整性仿真的本质,并在实际的工程实践中得到了验证和广泛的应用。

IBIS model is wildly used in high-speed PCB simulation. While the deficiency of intensive understanding of IBIS model largely debased the efficiency and correctness of simulation. This paper analyses the data sheet and corresponding waveform of IBIS model intensivley, and draws several new significant conclution of IBIS model in high-speed simulation. These new conclution reveal the essence of signal integrity simulation based on IBIS model, also are validated and wildly used in pratical engineering.
