Description
Outputs the given cellview (-lib -cell -view) to an OASIS or GDSII stream file, using the layer map file to map the OpenAccess layers and purposes to stream layers and data types.
Required Arguments
|
-cell s_topCellName
|
Specifies the name of the top cell to output.
|
|
-gds s_fileName
|
Specifies the name of the file to which the GDSII stream data will be written.
|
|
-ignore_layers {s_lpp…}
|
Excludes the given layer purpose pairs from processing. By default, data on all layer purpose pairs in the layer map file are written.
|
|
-layer_map s_fileName
|
Specifies the Stream/OASIS-to-OpenAccess Layer Map File to use to translate the stream layers and data types in the stream file to their respective OpenAccess layer names and purposes.
|
|
-lib s_libName
|
Specifies the name of the cellview library.
|
|
-oasis s_fileName
|
Specifies the name of the file to which the OASIS stream data will be written.
|
|
-output_layers {s_lpp…}
|
Limits processing to the specified layer purpose pairs. By default, data on all layer purpose pairs in the layer map file are written.
|
|
-view s_viewName
|
Specifies the name of the view to output.
|
Optional Arguments
|
-area {f_xlo f_ylo f_xhi f_yhi}
|
|
|
Specifies the rectangular area of the top cell to be written out, given by the lower left and upper right x and y coordinates for the area.
Default: Outputs the entire area
|
|
-keep_empty [ true | false ]
|
|
|
When set to true, empty cells and their instances are included.
Default: true
|
|
-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.
|
|
-rect_as_poly [ true | false ]
|
|
|
When set to true, rectangles are output as polygons.
Default: true
|
|
-v i_level
|
Specifies the level of verbosity for output messages.
Default: 0
|
|
-voltage_datatype {{f_voltage i_dataType}…}
|
|
|
Specifies voltage-datatype pairs. When shapes are output, if a shape belongs to a net with a voltage, the datatype for the shape is determined by comparing the net’s maximum voltage swing (Vmax-Vmin) with the table voltages, which must be given in increasing order. For example,
-voltage_datatype { 0.2 2 0.4 4 0.6 6 }
is interpreted as:
-
For 0 < voltage swing <= 0.2, use datatype 2.
-
For 0.2 < voltage swing <= 0.4, use datatype 4.
-
For 0.4 < voltage swing <= 0.6, use datatype 6.
