研究概况

我的主要研究兴趣为微电子与手机版交叉领域中的IC设计优化算法与大规模数值计算分析,已经从事EDA领域研究工作20多年。近年来,伴随着Moore定律的发展,我对IC设计中的互连线时延和噪声分析优化、大规模IC供电网络并行分析、低功耗物理设计优化、以及纳米工艺下面向可制造性(DFM)设计优化等一些国际前沿性问题进行了深入的研究。先后参加或主持了国家“核高基”科技重大专项、973、863、国家自然科学基金重大国际合作、国家自然科学基金等多项国际科研或合作项目。 主要工作分为以下三方面:

1. 对IC片上供电网络的分析和优化进行了系统和深入的研究:提出了基于GPU的P/G网络并行分析快速泊松方法,获得DAC 2009最佳论文提名奖,这是大陆学者首次获得该项荣誉;提出了基于三维模型的大规模P/G网络快速分析方法,成果发表在国际IC物理设计年会ISPD 2006及国际期刊Trans. On CAD上;提出了Dcap电容优化与布局结合等一系列P/G网络优化方法,成果发表在国际会议ICCAD 2009及国际期刊Trans. On CAS-II国际期刊上。

2. 对IC低功耗与时序物理设计优化进行了研究:提出了性能驱动的功耗关断物理优化方法,获得以功耗优化为主题的国际年会SGLVLSI 2008最佳论文奖,这是大陆学者首次获得该项荣誉;提出了基于电压岛多供电功耗优化方法、时钟关断功耗优化方法等,成果发表在国际IC物理设计年会ISPD 2008及国际期刊Trans. On VLSI上。

3. 对纳米工艺下工艺参数变化及可制造性(DFM)问题进行深入研究:与Synopsys合作提出了基于区域模型匹配的OPC热点探测方法,获得ICCAD 2006最佳论文提名奖;提出了一系列面向DFM的布线和优化算法,成果发表在国际会议及Trans. On VLSI等国际期刊上。
