我们开发了一个强大，高效，准确的工具，它集成了电感提取和仿真，称为INDUCTWISE。本文主要研究了电感的提取和仿真技术，主要包括两个部分。在第一部分，INDUCTWISE提取器，我们发现，最近提出的电感矩阵稀疏化算法，K-方法，虽然它的效率很大的好处，有一个重大的缺陷，在稳定性。我们给出了一个反例和一种补救方法，并给出了一个窗口分割算法来保持稀疏化方法的精度。第二部分，INDUCTWISE模拟器，展示了将节点分析公式与改进的K-方法相结合的巨大效率。实验结果表明，与SPICE 3相比，INDUCTWISE具有超过250/spl倍/加速比。所提出的稀疏化算法加速模拟器的另一个175/spl倍/和加速提取器的23.4/spl倍/在0.1%的误差。INDUCTWISE可以在18分钟内提取和仿真118 K导体RKC电路。
We have developed a robust, efficient, and accurate tool, which integrates inductance extraction and simulation, called INDUCTWISE. This paper advances the state-of-the-art inductance extraction and simulation techniques and contains two major parts. In the first part, INDUCTWISE extractor, we discovered that the recently proposed inductance matrix sparsification algorithm, the K-method, albeit its great benefit of efficiency, has a major flaw in the stability. We provide both a counter example and a remedy for it. A window section algorithm is also presented to preserve the accuracy of the sparsification method. The second part, the INDUCTWISE simulator, demonstrates great efficiency of integrating the nodal analysis formulation with the improved K-method. Experimental results show that INDUCTWISE has over 250/spl times/ speedup compared to SPICE3. The proposed sparsification algorithm accelerates the simulator another 175/spl times/ and speeds up the extractor 23.4/spl times/ within 0.1% of error. INDUCTWISE can extract and simulate an 118K-conductor RKC circuit within 18 minutes.
