[Shell]通过Shell脚本导出GDSII/OASIS文件

https://www.cnblogs.com/yeungchie/

常见的集成电路版图数据库文件格式有 GDSII 和 OASIS，virtuoso 提供了下面两个工具，可以用来通过命令行导出版图数据。

• strmout (导出为 GDSII 格式)

OASIS 的文件体积声称可以比 GDSII 小 10~50 倍，实际在我的使用中这个数字可以到 20+（以项目情况而定），当项目数据较大的情况下，文件小了确实可以加快运行速度、节省时间（估计是硬盘读写环节拖累了整体运行时间）。
oasisout 和 strmout 几个常用的参数都是相同的，下面讲下如何使用。

另外，命令的运行路径必须在 virtuoso 启动路径（能在当前路径下找得到 cds.lib 文件）。

参数解释

必要的

首先有几个必要的运行条件和参数。

• -library

  这个参数用来指定导出的单元库 (library) 名。

• -strmFile

  当使用 strmout 时，这个参数用来指定导出的 GDSII 文件名称。

• -oasisFile

  当使用 oasisout 时，这个参数用来指定导出的 OASIS 文件名称。

推荐的

其次还有几个是可选的参数，但是建议也指定一下。

• -topCell

  指定导出单元的顶层 Cell 名称，指定了顶层 Cell 就不会导出该顶层没有调用的单元，否则会导出当前库下的所有 Cell 。

• -view

  指定导出单元的顶层 View 名称，默认为 layout 。

• -runDir

  指定运行路径。

  注意这里的 运行路径 不同于前面提到的命令的运行路径。
  当定义了 -runDir 后 -strmFile、-oasisFile、-logFile、-summaryFile 等参数如果定义的是相对路径，则会以 -runDir 为参考。

• -logFile

  生成 log 文件，默认生成文件名为 strmOut.log、oasisOut.log 。

• -summaryFile

  生成 summary 文件，默认不生成。

• -layerMap

  指定 layermap 文件，默认情况是调用 attach tech 中的 layermap，当对层次转换有特殊要求时可以通过这个参数来指定自定义的 layermap 。

编写脚本 export_layout

下面写个脚本优化一下这个运行方式。

优化后的脚本有三个必要的参数需要指定

• -path
  指定 cds.lib 文件所在的文件夹路径
• -lib
  指定导出单元的顶层 Library 名称
• -cell
  指定导出单元的顶层 Cell 名称

通过 -path 参数来定义 virtuoso 启动路径，实现在任意路径下可运行，生成的文件都在当前路径下。

运行实例

例：cdslib 文件所在路径为 ../project

1. 导出版图 verify/ad01d0/layout 单元为 GDSII 文件。

   export_layout -path ../project -lib verify -cell ad01d0

2. 导出版图 verify/inv0d0/layout 单元为 OASIS 文件，指定输出文件名 inv.oasis，指定 log 文件为 inv.log 。

   export_layout -path ../project -lib verify -cell inv0d0 -file inv.oasis -oasis -log inv.log
