[|[ Shell ] 通过 Shell 脚本导出 CDL 网表
https://www.cnblogs.com/yeungchie/
通过 si 导出电路网表，实际上在 Virtuoso 中通过 export - cdl 和 Calibre LVS 的步骤中也是通过 si 来导出电路网表的，下面讲下如何使用。
command
下面是 si 的运行命令， $cdslibFile 为 cds.lib 文件。
si -batch -command netlist -cdslib $cdslibFile
si.env 在 si 的运行路径下需要提前准备好一个 si.env 文件，si 通过读取这个文件的内容来配置导出 cdl 所需要的信息。
文件的如何编写可以参考 help 文档：

【[|[ Shell ] 通过 Shell 脚本导出 CDL 网表】这个例子中导出的顶层电路单元是 simLibName = "stdcel"
simCellName = "TOP"
simViewName = "schematic"
simSimulator = "auCdl"
simNotIncremental = 't
simReNetlistAll = nil
simViewList = '("auCdl" "cdl" "schematic" "cmos_sch" "gate_sch" "cmos.sch" "gate.sch" "symbol")
simStopList = '("auCdl" "cdl")
hnlNetlistFileName = "TOP.cdl"
resistorModel = ""
shortRES = 2000.0
preserveRES = 't
checkRESVAL = 't
checkRESSIZE = 'nil
preserveCAP = 't
checkCAPVAL = 't
checkCAPAREA = 'nil
preserveDIO = 't
checkDIOAREA = 't
checkDIOPERI = 't
checkCAPPERI = 'nil
simPrintInhConnAttributes = 'nil
checkScale = "meter"
checkLDD = 'nil
pinMAP = 'nil
preserveBangInNetlist = 'nil
shrinkFACTOR = 0.0
globalPowerSig = ""
globalGndSig = ""
displayPININFO = 't
preserveALL = 't
setEQUIV = ""
incFILE = "./Subcircuit/3t_device.cdl"
auCdlDefNetlistProc = "ansCdlHnlPrintInst"
stdcel/TOP/schematic，我们只关心其中几个常用的变量：- simLibName ( Library Name )
stdcel - simCellName ( Top Cell Name )
TOP - simViewName ( View Name )
schematic - hnlNetlistFileName ( Output CDL Netlist File )
- incFILE ( Include File )
- auCdlDefNetlistProc ( Analog Netlisting Type )
这个变量决定 pin 的连接方式- ansCdlSubcktCall ( Connection By Order )
顺序连接 - ansCdlHnlPrintInst ( Connection By Name )
命名端口连接，一般选择这个来保证 IP/Digital 网表的连接
- ansCdlSubcktCall ( Connection By Order )
Run Directory 直接由 si 的运行路径来决定。export_cdl 明白了 si 的使用方法，现在可以写一个 shell 脚本，在 Terminal 操作，实现便捷地导出指定电路单元的 cdl 文件。
