ID:20013 Ignored <count> assignments for entity "<name>" -- entity does not exist in design

CAUSE: The design has one or more assignments for an entity that does not exist in the design. This error can also occur if the entity does not have the same case for case-sensitive languages (for example, Verilog HDL), or if the entity was not actually used in the design.

ACTION: Make sure the assignments for the entity have the correct entity name, make sure the entity exists in the design, or remove the assignment.
