) ;spacings

spacingTables(
( minSameNetSpacing tx_layer
 (( "width" nil nil )
  [f_default]
 )
 (g_table)
)

) ;spacingTables

Specifies the minimum spacing between shapes on the same net (electrically equivalent geometries) on a layer. The spacing between the shapes can be dependent on the width of the shapes.

This constraint is required if same-net spacing is less than the different-net spacing specified by the minSpacing (One layer) constraint.

Values

tx_layer	The layer on which the constraint is applied. Type: String (layer and purpose names) or Integer (layer number)
f_spacing	The spacing between same-net shapes on a layer must be greater than or equal to this value.
"width" nil nil
	This identifies the index for table.
g_table	The format of a table row is as follows: (f_width f_spacing) where, f_width is the width of the geometry and f_spacing is the minimum spacing required between shapes with width greater than or equal to f_width. Type: A 1-D table specifying floating-point width and spacing values

Parameters

f_default

The spacing value to be used when no table entry applies.

Example

The same-net spacing on Poly1 must be at least 1.0 and the same-net spacing on Metal2 must be at least equal to the value of the technology parameter minsamenetspace1.
