安捷伦科技多年来一直非常努力地改善它的层次结构设计方法。最新的改善成果,就是在设计流程中加入实体合成工具。基本的限制将180nm 技术与300MHz 设计中的合成及布局与路由(place-and-route)-以电线负载模式连结-做了明显的区隔。传统的合成已经在去年被实体合成所取代了,即使它包含以时序为主的布局与路由等延伸功能也不例外,因为实体合成能提 Agilent Technologies has worked very hard for many years to improve its hierarchical design approach. The latest improvement is adding physical synthesis tools to the design process. The basic limitations make a clear separation between the 180nm technology and the 300MHz design for place-and-route wire-to-wire mode bonding. The traditional synthesis was superseded by physical synthesis last year, even though it includes extended features such as timing-based layout and routing, as physical synthesis can provide
