摘要: 摘要: 
针对超大规模集成电路中复杂互连线网络的快速仿真需求,提出并实现了含频变分布参数互连线网络的并行仿真技术.建立频变互连线的等效传输线模型,并借助多端口等效模型将互连线部分与其他电路单元相分离,实现互连线仿真的并行化.互连线采用时域有限差分方法求解,而除去互连线的其他电路则在集成电路模型程序(SPICE)中进行仿真,两者在同一时间步内交换数据.基于该技术开发出并行仿真软件FdSPICE.数值实验证明,该软件计算精度较高,可有效提高复杂互连线网络的仿真效率.

Abstract:

Abstract: A parallel algorithm was presented to satisfy the demand of efficient simulation of complex interconnect networks with frequency-dependent parameters. By means of the equivalent multi-port models, the interconnects are separated from other circuit elements, and thus makes the parallel simulation feasible. The finite-difference time-domain method is utilized for the solution of interconnects while other circuit elements are simulated in the simulation program with integrated circuit emphasis(SPICE)environment, and their simulation results are exchanged in every time step. Based on the proposed technique, a program named FdSPICE was developed for parallel simulation of interconnect networks. The numerical examples show that accurate results are obtained by this program and the simulation efficiency is improved significantly.
