snapPatternDefOffset

spacings(
( snapPatternDefOffset
 {'horizontal | 'vertical | 'snapPatternDef t_name}
 f_offset
)
) ;spacings

(Virtuoso Advanced Node for Layout Only) Specifies the snapPatternDef offset. The offset can be specified either for all snapPatternDefs in a particular direction or for a particular snapPatternDef.

The constraint applies to both snapPatternDefs and widthSpacingSnapPatternDefs.

For widthSpacingSnapPatternDefs, this constraint overrides the offset of the widthSpacingSnapPatternDef, not the offset of the widthSpacingPattern. In other words, it shifts the period grid, not the tracks within the period.

Values

f_offset

The offset value.

Parameters

'horizontal | 'vertical

  

The direction in which the offset is measured.

'snapPatternDef t_name

The snapPatternDef name to which the offset requirement applies.

Example

The offset required for M2_globalGrid snapPatternDef is 0.1.

spacings(
    ( snapPatternDefOffset 
     'snapPatternDef "M2_globalGrid"
0.1
)
) ;spacings
