VHDL Architecture Body warning at <location>: secondary unit already exists -- overwriting existing secondary unit with new secondary unit

CAUSE: In an Architecture Body at the specified location in a VHDL Design File (.vhd), you declared a secondary unit for a design entity. However, you already declared the secondary unit in the same file, or in a different file for the same design entity. As a result, Integrated Synthesis replaced the existing secondary unit with the new secondary unit.
ACTION: If you do not want Integrated Synthesis to overwrite the existing secondary unit, or to avoid receiving this message in the future, change the new secondary unit so it has a unique name.
