Constraint Manager – Same Net Spacing Domain
Same Net Spacing rules are managed entirely within the Same Net Spacing domain in
Constraint Manager. An equivalent Same Net DRC represents each Spacing DRC. The
Same Net domain is structured similarly to the Spacing domain, in terms of constraint
inheritance and overrides. Constraint objects unsupported in the domain are Net Class-Class
and Region Class-Class, as they are used exclusively for net-net rules.
For more information, see Domains, Workbooks, Worksheets, and Cells in the
Constraint Manager User Guide.

Same Net Constraint Set
The Same Net system supports a Same Net CSet, abbreviated SNSC, which can be applied
to net or hierarchical elements. The CSet enables the Same Net DRC on a layer basis.
For more information, see the Objects – Create – Same Net Spacing CSet command in
the Constraint Manager Reference.
