如果你拥有针对65nm甚至90nm节点的工具,转换到45nm节点就不需要更换工具。但设计者转到这一节点时必须采用一些先进的设计技术,并了解一些新的设计规则,代工厂用这些规则来确保SoC设计能达到可接受的成品率。
If you have tools for 65nm or even 90nm nodes, you do not need to change tools when you switch to 45nm nodes. But when designers turn to this node, they have to adopt some advanced design techniques and learn some new design rules that foundries use to ensure that SoCs are designed to deliver acceptable yields.
