Value Types

minSameNetSpacing constraints have the following value types:

• Value
  Specifies the minimum spacing, edge-to-edge, between shapes on the specified layer and on the same net.
  

  Format	Example
  Tcl	set_layer_constraint -constraint minSameNetSpacing \ -layer s_layer -Value f_space

• OneDTblValue
  Specifies the minimum spacing based on width.
  

  Format	Example
  Tcl	set_layer_constraint -constraint minSameNetSpacing \ -layer s_layer -row_name width \ -OneDTblValue {{f_width f_space}…}

• TwoDTblValue (custom, derived)
  See minSpacing for examples.

Parameters

• widthLengthTableType (IntValue) specifies the table type when minSameNetSpacing is a TwoDTblValue table. The values are given in Table 16-1.
• distanceMeasureType (IntValue, optional) specifies the spacing measurement method as Euclidean (0, default) or Manhattan (1). For information on this parameter, see Euclidean and Manhattan Spacing Constraints.
• eolAddSpace (OneDTblValue, optional) specifies additional spacing required based on the wire width.
• eolRadialCheck (BoolValue, optional) enables radial checking from the wire corners.
• oaSpacingDirection (StringAsIntValue, optional) specifies the measurement direction. anyDirection 0 Horizontally and vertically (default) horizontalDirection 1 Horizontally only verticalDirection 2 Vertically only

Examples

• Fixed Value
  This example sets the minimum same net spacing on poly1 to 1.0.
  

  Format	Example
  Tcl	set_layer_constraint -constraint minSameNetSpacing \ -layer poly1 -Value 1.0
  Virtuoso	spacings( ( minSameNetSpacing poly1 1.0 ) )
