# 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)
