-input1_scratch_layer i_scratchID

Uses a scratch layer from a previous Boolean operation for lpp1 shapes.

-lpp1 {s_layerlpp …}

Specifies the first LPPs. For details on the LPP notation, refer to Specifying Input Layer Purposes.

-lpp1_levels {i_startLevel [i_endLevel]}

Limits lpp1 shapes to those on the specified levels. If start and end levels are given, all levels in between are included. The top level is 0.
Default: all levels

-lpp1_net_names {s_netName…}

Limits lpp1 shapes to the named nets.

-lpp1_net_set d_setObj

Limits lpp1 shapes to the nets in the set.

-no_sync

By default, the OpenAccess database is immediately updated with the results of this operation. If this argument is given, the results will not be saved until the database is saved (write_db).

-output_lpp s_lpp

Specifies the output LPP for the generated shapes.

-output_net_name s_netName

Adds shapes to the named net. When this argument is given, the -no_sync argument is ignored. Shapes that are created by this command will be saved with the named net when the database is saved.

-output_scratch_layer i_scratchID

Adds generated shapes to a scratch layer identified by the positive integer. This scratch layer can be used as an input layer in subsequent Boolean operations using the -input1_scratch_layer or -input2_scratch_layer arguments for the current design. Scratch layers cannot be displayed but can be removed using geom_remove_scratch_layers.

-output_set d_setObj

Adds generated shapes to the given set.

-polygons

Generates output shapes as polygons, rather than individual rectangles. By default, individual rectangles are generated.

-region {f_xlo f_ylo f_xhi f_yhi}

Specifies the area of the operation given the lower-left coordinate and the upper-right coordinate.

-route_topology s_topologyName

(Applies only if -output_net_name is given with the name of an existing power or ground net) Sets the routeTopology property for the output shapes as follows:

block_ring

BlockRingRouteTopology

cell_row_strap

StandardCellWireRouteTopology

core_ring

RingRouteTopology

stripe

StripeRouteTopology (this is the default)

-set1 d_setObj

Limits lpp1 shapes to shapes in the set.

i_count

Is the total number of shapes created.
