U_SET lets you group cells regardless of hierarchy or where they appear in the design. All cells with the same set_name are members of the same RPM set.

Design elements tagged with a U_SET constraint can be primitive or non-primitive symbols.

When attached to non-primitive symbols, the U_SET constraint propagates downward through the hierarchy to all the primitive symbols below it that are assigned RLOC constraints.
