研究概況
自1999年開始，一直從事超大規模積體電路互連寄生參數提取的算法研究與軟體開發。2004年至2007年，面向矽基數模混合電路和射頻電路的設計，我著重研究了基於邊界元法的襯底耦合參數提取和高頻阻抗提取算法。
2005年至2008年，多次訪問美國加州大學聖地亞哥分校（UCSD），在互連分析與電路仿真方面開展了合作研究。我的主要學術貢獻有：
1. 發展、提出了基於直接邊界元法的三維電容提取快速算法。我主持開發的兩個軟體原型——QBEM和HBBEM（與王澤毅教授一起）——作為電容求解引擎，已被美國ICScape、日本JEDAT等公司嵌入面向超大規模積體電路設計和液晶平面顯示器設計的商業軟體中。HBBEM的核心算法被IBM Watson研究中心採用並用於開發IBM的首要三維互連電容求解器軟體CSurf。
2. 提出了多項基於VLSI新工藝特點的互連電容、電阻提取算法，用於處理懸浮金屬啞元、多通孔等複雜結構以及片內隨機工藝變動。我在該方向的論文發表於期刊IEEE Trans. Computer-Aided Design、IEICE Trans. Electronics和會議DATE 2008、DAC 2009中，獲得學術界和工業界的關注。
3. 針對數模混合和射頻晶片的襯底耦合問題，提出了適應性強、計算效率高的襯底電阻提取算法和頻變參數提取算法。我在該方向的論文發表於期刊IEEE Trans. Computer-Aided Design中。
4. 提出了基於階躍回響的互連信號眼圖（eye-diagram）預測算法，並與UCSD的合作者一起提出了用於片外互連的無源均衡電路設計最佳化算法，發展了基於頻域分析的大規模互連電路瞬態仿真算法。我在該方向的論文發表於期刊IEEE Trans. Computer-Aided Design、IEICE Trans. Electronics和國際會議DAC 2008、ICCAD 2008中。
在積體電路建模與仿真、尤其是寄生參數提取領域，我是國際上一位比較活躍的研究者，多次被邀請擔任國際會議程式委員會委員，並為本領域最重要的國際期刊審稿。
