Eda start-up Clear Shape Technologies, the worst-kept secret in the DFM (design-for-man-ufacturing) market, in November formally announced itself and its two DFM tools. In 2003, industry veterans Atul Sharan, Yao-Ting Wang, and Fang-Cheng Chang, respectively chief executive officer, chief technology officer, and vice president of engineering, founded the company with the idea that advanced process technologies at 65-nm and smaller processes will require model-based physical verification, not just rule-based DRC (design-rule checking). "We've been around for three years now and haven't announced ourselves until now because DFM requires complex engagements," Sharan says. "You have to get validated in the fabs and create a tool that is production-ready."
