Export CDL ( Circuit Description Language ) File
-------------------------------------------------
Usage: export_cdl -cdslib cdslibFile -lib libName -cell cellName [ OPTIONS ]

    -cdslib     Path of cds.lib file
    -lib        Schematic top cell libName
    -cell       Schematic top cell cellName
    -view       Schematic top cell viewName ( Default: schematic )
    -file       Output netlist file name    ( Default: ./<cellName>.cdl )
    -include    Include subckt file name
    -order      Netlisting Type Connection By Order ( The default is By Name )
    -h, -help   Display this help

Examples:   export_cdl  -cdslib ./cds.lib  -lib Xeon  -cell X999  -include ./subckt.cdl

Output:     Netlist file: X999.cdl
