split_net

split_net
{-all | net {s_netName…} | -set d_setObj} 
-width f_userunit

Description

Splits a routed wide width net into individual segments of the given width. This is useful when the routed wire width is greater than the maximum width for the design or when strand routing can give a better result for current load and spacing requirements. The net is split to maximize the number of strands within the wide wire bounds.

Arguments

-all

Splits all nets in the design with wire widths greater than the given width (-width).

-net {s_netName…}

Splits all nets in the list with wire widths greater than the given width (-width).

-set d_setObj

Splits all nets in the set with wire widths greater than the given width (-width).

-width f_userunit

Splits nets with wire widths greater than this value into multiple strands of this width.

Examples

The following command splits nets wider than 0.3 microns into stranded routes with wires of width 0.3 microns.

split_net -all -width 0.3
