ID:10802 VHDL Unconstrained Array error at <location>: formal "<name>" must be constrained

CAUSE: Your design declared the specified formal on an entity, component, or subprogram with an unconstrained array type. Later on, you instantiated the entity or component or called the subprogram without providing the formal with an index constraint. In VHDL, an unconstrained formal associated with an actual as a whole will inherit the constraint of the actual. If the unconstrained formal has partial associations, the index constraints for the unconstrained dimensions will be the maximum and minimum values of their index expressions across all partial associations.

ACTION: Provide a constraint for the formal by associating it with an actual, or declare it with a constrained array type.
