[ 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用来在 Shell 中导出版图数据。
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达到 20+ 倍（以项目情况而定），某些情况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）。
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 。
下面写个脚本优化一下这个运行方式。

Export Layout ( GDSII or OASIS ) File
-------------------------------------------------
Usage: export_layout -path cdslibDir -lib libName -cell cellName [ OPTIONS ]
-path Path where the cds.lib file is located
-lib Layout top cell libName
-cell Layout top cell cellName
-view Layout top cell viewName ( Default: layout )
-file Output file name ( Default: <cellName>.gds or <cellName>.oasis )
-log Log file ( Default: export_layout.log )
-sum Summary file
-layermap Specified the layermap file
-oasis Specified the file format is OASIS, and GDSII if not specified
-h, -help Display this help
Examples: export_layout\\
-path \$project/work/
-lib Xeon
-cell X999
-oasis
Output: OASIS file - X999.oasis

## 不同的文件格式
if [[ $OASIS ]]; then
if [[ ! $file ]]; then file="${cellName}.oasis" ; fi
command="oasisout -oasisFile $file"
else
if [[ ! $file ]]; then file="${cellName}.gds" ; fi
command="strmout -strmFile $file"
fi
command="$command -runDir $runDir -library $libName -topCell $cellName -view $viewName -logFile $logFile $sumCmd $mapCmd"
# 运行
exec $command 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
导出版图
verify/ad01d0/layout单元为 GDSII 文件。export_layout -path ../project -lib verify -cell ad01d0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
版图数据导入
- strmin
- oasisin
顾名思义，用法和导出过程大同小异，这里就不赘述了。
