可以用下面的命令: dbGet [dbGet top.insts.name *LTIE* -p].name 如何得到库中的Tie High/Low Cell名称呢? 方法1: 一般Foundary都会提供Cell list以及每种Cell功能介绍的doc文档,可以在里面查看,也可以在Cell LEF中找到: MACRO TIELO CLASS CORE ; FOREIGN TIELO 0 0 ; ORIGIN 0 0 ; SIZE 1.32 BY 5....

如果hard macro 的placement status 是PLACED, 则Hard macro 的面积会算在『leaf cell 面积』 跟『可用总面积』内; leaf cell 的面积可从lib 直接读出,也可从lef 中读出『SIZE X BY Y』计算得到;通常std cell 和hard macro 是矩形,从lib 中读出的面积跟从lef 中读出『SIZE X BY Y』计算得到的面积是相等...
<path to standard cell library>/<standard cell>.gds \ } \ -mode ALL \ -units 1000 \ -dieAreaAsBoundary 上面命令例子里加了-attachInstanceName 127 选项,意思时把instance 的名字放到127层。 4. VirtuosoXStream In 最后就是 Virtuoso 导入上面生成的 GDS文件了。
With block sizes growing in both cell count and complexity, the number of macros that need to be positioned in the floorplan is exploding. The Innovus system offers mixed-macro and standard-cell placement, which enables macro locations to be automatically generated, reducing the time to cre...

以一个Block Level的APR为例,需要工艺库、综合输出的数据、顶层Layout的要求等。 一、工艺库,包括lib库、lef、captable、qrc等。 lib库是stdcell库,具体包括stdcell的逻辑、面积、时序、功耗等信息。lef包括tech lef和stdcell lef。tech lef是金属层定义,而stdcell lef定义了stdcell的大小、出pin位置等。captable...
