XDC File Scoping Properties - XDC File Scoping Properties - 2026.1 English - UG903

Activate constraint scoping by setting these properties on the XDC files:

SCOPED_TO_REF

Apply constraints to all instances of the specified module or entity.

SCOPED_TO_CELLS

Apply constraints to each hierarchical cell in the specified list.

SCOPED_TO_REF + SCOPED_TO_CELLS

Apply constraints to each listed cell located inside the specified module or entity.

1. Locate the XDC file for your constraints.
2. Choose whether to scope by module name, cell list, or both.
3. Set SCOPED_TO_REF, SCOPED_TO_CELLS, or both in the XDC file.
4. Save and verify the constraints apply only to the intended design elements.

Vivado automatically sets these properties for IP cores you add to an RTL project through the IP catalog.
