|
If either -calibre_run_dir or -calibre_run_prefix is given, annotation files generated by Mentor Graphics® Calibre® LVS will be loaded, if they exist, including:
-
Calibre Layout Netlist Names (LNN) files that are used to change the names of nets from their stream property number annotation to their net list names.

Port cell files and Spice network files that are used to create instance terminals and device names for instances.
This argument specifies the directory to search for these files.

|
|
-calibre_run_prefix s_prefix
|
|
|
If either -calibre_run_dir or -calibre_run_prefix is given, annotation files generated by Calibre LVS will be loaded, if they exist. This argument limits the files to those that include the given prefix in their name (.s_prefix.lnn, s_prefix.devmap, s_prefix.port_cells, and s_prefix_pin-xy.spi).
Default: s_prefix is the top cell name given by the -cell argument.

-cell2 s_topCellName
|
Specifies the top-level cell to load for the secondary design given by -gds2 or -oasis2.
|
|
-detect_vias [ true | false ]
|
|
|
When true, enables the automatic detection of vias.
The layer map file, given by the -layer_map argument, must specify the appropriate material types, metal and cut, for the via metal and cut layers. Other layers can be type other.
The layer map file must also specify the fabrication order for the layers using ascending mask numbers. For example, metal1 would be 1, via1 would be 2, metal2 would be 3, and so on.
Default: Via detection is enabled.

|
-device_prop_number i_annotated_stream_device_prop_number
|
|
|
Specifies stream property number that is used to specify devices.

|
-gds2 s_fileName
|
Specifies the name of the GDSII stream file to open for a second design that will be merged with the primary design given by -gds or -oasis. Cannot be used with the -oasis2 argument.
|
|
-ignore_layers {{i_layerNumber:i_dataTypeNumber}…}
|
|
|
Excludes from loading the specified subset of layers, given by i_layerNumber:i_dataTypeNumber pairs.
For example,
{2:0 4:0 5:0}
will exclude layer and data types for
-
Layer 2, data type 0
-
Layer 4, data type 0
-
Layer 5, data type 0
This argument cannot be used with -load_layers, -ignore_layers_file, or -load_layers_file.
Default: No layers are ignored.
|
|
-ignore_layers_file s_fileName
|
|
|
Specifies a file that contains the list of layers to be excluded, each represented by a pair of numbers, separated by a space, one per line.
i_layerNumber i_dataTypeNumber
This argument cannot be used with -ignore_layers, -load_layers_file, nor -load_layers.
|
|
-instance_prop_number i_annotated_stream_instance_prop_number
|
|
|
Specifies stream property number that is used to specify instances.
Default: 6
|
|
-load_layers {{i_layerNumber:i_dataTypeNumber}…}
|
|
|
Loads only the specified subset of layers, given by i_layerNumber:i_dataTypeNumber pairs. The listed pairs must be specified in the layer map file.
For example,
{0:0 1:0 2:0}
will load only layer and data types for
-
Layer 0, data type 0
-
Layer 1, data type 0
-
Layer 2, data type 0
This argument cannot be used with -ignore_layers, -ignore_layers_file, nor -load_layers_file.
Default: All layers are loaded.
|
|
-load_layers_file s_fileName
|
|
|
Specifies a file that contains the list of layers to be loaded, each represented by a pair of numbers, separated by a space, one per line.
i_layerNumber i_dataTypeNumber
This argument cannot be used with -ignore_layers, -ignore_layers_file, nor -load_layers.
|
|
-net_prop_number i_annotated_stream_net_prop_number
|
|
|
Specifies stream property number that is used to specify nets.
Default: 5
|
|
-oasis s_fileName
|
Specifies the name of the OASIS stream file to open. Cannot be used with the -gds argument.
|
|
-oasis2 s_fileName
|
Specifies the name of the OASIS stream file to open for a second design that will be merged with the primary design given by -gds or -oasis. Cannot be used with the -gds2 argument.
