set_routing_grid 
{[ -x f_grid ] [ -y f_grid ] [ -x_offset f_offset ] [ -y_offset f_offset ]} 
[ -layer {s_layerName …} | -rs s_routeSpec ]

Sets r outing grid parameters for one or more layers, a route spec, or the entry layer in the active window.

Grid and offset values must be multiples of the manufacturing grid.

`-layer` {s_layerName …}
	Specifies the layer names. If not specified, all layers are set.
`-rs` s_routeSpec	Specifies the name of the route spec.
`-x` f_grid	Specifies where route segments can begin and end, and where vias can be placed on the x-axis.
`-x_offset` f_offset
	Specifies the offset from 0 on the x-axis for the router to use for this layer.
`-y` f_grid	Specifies where route segments can begin and end, and where vias can be placed on the y-axis.
`-y_offset` f_offset
	Specifies the offset from 0 on the y-axis for the router to use for this layer.

The following example sets the x- and y-axis routing grid values for met1 and met2.

set_routing_grid -layer {met1 met2} -x 2.0 -y 2.0
