NAME
add_pdn_stripe - add pdn stripe
SYNOPSIS
add_pdn_stripe -layer layer_name [-grid grid_name] [-width width_value] [-followpins] [-extend_to_core_ring] [-pitch pitch_value] [-spacing spacing_value] [-offset offset_value] [-starts_with POWER|GROUND] [-extend_to_boundary] [-snap_to_grid] [-number_of_straps count] [-nets list_of_nets]
DESCRIPTION
Defines a pattern of power and ground stripes in a single layer to be added to a power grid.
Example usage:
add_pdn_stripe -grid main_grid -layer metal1 -followpins
add_pdn_stripe -grid main_grid -layer metal2 -width 0.17 -followpins
add_pdn_stripe -grid main_grid -layer metal4 -width 0.48 -pitch 56.0 -offset 2 -starts_with GROUND
OPTIONS
-layer: Specifies the name of the layer for these stripes.
-grid: Specifies the grid to which this stripe definition will be added. (Default: Last grid defined by define_pdn_grid).
-width: Value for the width of stripe.
-followpins: Indicates that the stripe forms part of the stdcell rails, pitch and spacing are dictated by the stdcell rows, the -width is not needed if it can be determined from the cells.
-extend_to_core_ring: Extend the stripes to the core PG ring.
-pitch: Value for the distance between each power/ground pair.
-spacing: Optional specification of the spacing between power/ground pairs within a single pitch (Default: pitch / 2).
-offset: Value for the offset of the stripe from the lower left corner of the design core area.
-starts_with: Specifies whether the first strap placed will be POWER or GROUND (Default: grid setting).
-extend_to_boundary: Extend the stripes to the boundary of the grid.
-snap_to_grid: Snap the stripes to the defined routing grid.
-number_of_straps: Number of power/ground pairs to add.
-nets: Limit straps to just this list of nets.
