Cadence Guo-Jun Liu: China has gradually have the 65nm chip design capability

Few years ago, 65nm chip design projects have been launched in China one after another up. China has been gradually chip design companies have the 65nm chip design capabilities. Meanwhile, the 65nm feature size and ever more There is a big design projects, so that, on some important aspects to the upstream and downstream industries of common concern. A concern to ensure IP quality IP issues and Although not directly related to 65nm chip design, as some of their customers in the actual design of the project encountered problems is one of the larger IP quality issues, and should therefore lead to the industrys attention. With a more advanced chip design technology, the chip size increases, more and more demands on the IP. Present different IP sources, different foundries, how to integrate and verify the IP, in particular the quality of...

Cainan Xiong: dense infiltration of foreign investment in China will be a dynamic semiconductor

First Financial Daily recently read the "foreign post-crisis time-intensive penetration of Chinas semiconductor industry self-controlled storage worries," a text, which usually comes to a number of matters of concern, hope and readers to share some personal views. Penetration of foreign capital-intensive semiconductor industry in China is a good thing Penetration of foreign capital-intensive need to worry about. In fact, people to copy our "bottom" is a good thing, because it means something worthy of our people, "copy"! Only the "bottom" is now operating efficiency is not good, can not see the future, can not make contributions to society, and even the governments burden! Now someone wants to take over, must come prepared with a good policy to enable businesses to play a benefit. This is the enterprise itself, shareholders, employees,...
