horizontalPitch (One layer)

routingGrids(
( horizontalPitch [tx_layer]
 ['firstLastPitch f_firstLastPitch]
 f_pitch
)

) ;routingGrids

Specifies the horizontal pitch (distance) between the routing tracks on the specified layer. If layer is not specified, the constraint sets the default pitch for all layers for which a horizontal pitch is not explicitly assigned.

Values

tx_layer	The layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_pitch	The distance between the vertical routing tracks on the specified layer. If 'firstLastPitch is specified, this distance applies only to the tracks between the first and last routing tracks.

Parameters

'firstLastPitch f_firstLastPitch
	The distance of the first and the last routing track from the cell row boundary.

Example

The horizontal pitch is 0.14 for the first and last routing tracks and 0.1 for intermediate tracks. This applies to all layers for which horizontal pitch is not explicitly assigned.
