NAME
add_sroute_connect - add sroute connect
SYNOPSIS
add_sroute_connect -layers list_of_2_layers -cut_pitch pitch_value [-net net] [-outerNet outerNet] [-fixed_vias list_of_vias] [-max_rows rows] [-max_columns columns] [-metalwidths metalwidths] [-metalspaces metalspaces] [-ongrid ongrid_layers] [-insts inst]
DESCRIPTION
The add_sroute_connect command is employed for connecting pins located
outside of a specific power domain to the power ring, especially in cases where
multiple power domains are present. During sroute, multi-cut vias will be added
for new connections. The use of fixed vias from the technology file should be
specified for the connection using the add_sroute_connect command. The use
of max_rows and max_columns defines the row and column limit for the via stack.
Example:
add_sroute_connect -net "VIN" -outerNet "VDD" -layers {met1 met4} -cut_pitch {200 200} -fixed_vias {M3M4_PR_M} -metalwidths {1000 1000} -metalspaces {800} -ongrid {met3 met4} -insts "temp_analog_1.a_header_0"
OPTIONS
-net: The inner net where the power ring exists.
-outerNet: The outer net where instances/pins that need to get connected exist.
-layers: The metal layers for vertical stripes within inner power ring.
-cut_pitch: Distance between via cuts when the two layers are parallel, e.g., overlapping stdcell rails. (Default:200 200)
-fixed_vias: List of fixed vias to be used to form the via stack.
-max_rows: Maximum number of rows when adding arrays of vias. (Default:10)
-max_columns: Maximum number of columns when adding arrays of vias. (Default:10)
-metalwidths: Width for each metal layer.
-metalspaces: Spacing of each metal layer.
-ongrid: List of intermediate layers in a via stack to snap onto a routing grid.
-insts: List of all the instances that contain the pin that needs to get connected with power ring. (Default:nothing)
