|
-all
|
Performs process antenna checks on all nets.
|
|
-annotate_diodes [ true | false ]
|
|
|
Creates annotations for added diodes. Defaults to true.
The annotations are added to the annotation:viaOpt purpose for the metal layer and are listed by net as Antenna Diodes in the Optimizations page of the Annotation Browser.
|
|
-annotate_jumpers [ true | false ]
|
|
|
Creates annotations for added jumpers. Defaults to true.
The annotations are added to the annotation:viaOpt purpose for the metal layer and are listed by net as Antenna Jumpers in the Optimizations page of the Annotation Browser.
|
|
-check {[PAR][CAR]}
|
Determines which checks to perform: PAR (Partial Area Ratio), CAR (Cumulative Area Ratio).
Default: PAR and CAR, whichever ratios are defined in the LEF file
|
|
-clear_annotations
|
Removes existing violation annotations of the same check type before performing this check. If not specified, existing violations are not cleared.
|
|
-diff_use_only [ true | false ]
|
|
|
When set to true, applies area factor to layers when connected to diffusion. If no layers are specified, then area factor is applied to all layers when connected to diffusion.
Default: false
|
|
-exclude_nets {s_netName …}
|
|
|
Ignores the given nets from the check. This argument is ignored if -net is specified.
|
|
-fillcell_distance f_micron
|
|
|
Specifies the distance in microns from the net to search for filler cells to use for diode insertion locations.
|
|
-layer_list {s_layerName…}
|
|
|
Specifies the layers that jumpers can be added to. Only validRoutingLayers that are also in this list can be used. By default, jumpers can only be added on validRoutingLayers.
|
|
-layer_range {s_layerName s_layerName}
|
|
|
Specifies the range of layers that jumpers can be added to. Only validRoutingLayers that are also in this range can be used. By default, jumpers can only be added on validRoutingLayers.
|
|
-max_wires_to_push i_count
|
|
|
Specifies the number of wires that can be pushed for a single jumper. Default is 2.
|
|
-model
|
Specifies which oxide models to use: OXIDE1, OXIDE2, OXIDE3, OXIDE4.
Default: OXIDE1
|
|
-net s_netName
|
Performs process antenna checks on the given net.
|
|
-noIOPinDefault [ true | false ]
|
|
|
Prevents the antenna checker from using IO pin default values:
-
ANTENNAINPUTGATEAREA -
ANTENNAOUTPUTDIFFAREA -
ANTENNAINOUTDIFFAREA
By default, these values are used for any input that does not have a gate area or any output that does not have diode area.
|
|
-push [ true | false ]
|
Permits pushing of neighboring geometry to provide room for jumpers. Default is true.
|
|
-push_vias [ true | false ]
|
|
|
Permits pushing of vias. Default is true.
|
|
-set d_setObj
|
Performs process antenna checks on nets in the given set.
|
|
-silent [ true | false ]
|
|
|
Prevents messages from being output.
Default: false
|
|
-use_diodes [ true | false ]
|
|
|
Adds diodes to remove violations. Default is true
|
|
-use_factors
|
Uses area factors when computing PAR values.
|
|
-use_jumpers [ true | false ]
|
|
|
Adds jumpers to remove violations. Default is true
|
|
-via_rotation
|
Permits jumpers to use rotated vias. Default is false.
