Description

Creates either a GDSII or OASIS file that contains the shapes that are attached to the given nets. You can optionally limit the output to shapes on specific layers. By default, for each net in the list (-nets), shapes in the net are assigned to the datatype corresponding to the drawing purpose for the shape’s layer, according to the layer map. If -starting_datatype is given, the first net will use this number and the datatype number will be incremented by one for each subsequent net.

Required Arguments

-gds s_fileName  

Specifies the name of the file to which the GDSII stream data will be written.

-layer_map s_fileName

Specifies the Stream/OASIS-to-OpenAccess Layer Map File to use for mapping OpenAccess layer names and purposes to their respective stream layers and datatypes.

-nets {s_netName…}  

Limits output to the specified nets.

-oasis s_fileName  

Specifies the name of the file to which the OASIS stream data will be written.

Optional Arguments

-layers {s_layerName…}

  

Limits output to shapes on the given layers.

-net_datatype_map s_fileName

  

Specifies the name of the file to which the mapping of net names and datatype is output. Must be used with -starting_datatype.

Default: .netDatatypeMapFile

-purp_in_oasis_lmap [ true | false ]

By default and when set to true, layer and purpose names are output to the OASIS file layer map section. When set to false, the purpose names are excluded. This is useful if your OASIS file reader cannot process purpose names.

-starting_datatype i_number

  

Specifies the starting datatype for the output stream. Shapes for the first net are assigned to this datatype, and the datatype number will be incremented by one for each subsequent net.

Value Returned

None
