ID:16228 One or more registers failed to be packed into a DSP bank due to VCC inputs

CAUSE: VCC inputs to a DSP block prevented some registers from being packed inside the DSP block. Packing these registers will cause different behavior at startup and/or after reset.

ACTION: Please refer to "Fixed Point DSP Register Packing Details" table in the Fitter Report to determine which DSP blocks were affected. Remove VCC inputs to the DSP block or add an explicit register with the synthesis preserve attribute to indicate the altered behavior is acceptable.
