ID:13842 VHDL information at <location>: object "<name>" is never used

CAUSE: In a VHDL Design File (.vhd) at the specified location, you specified an object that is either a variable in a process or an item in an array. However, the design never uses the object on the right-hand side (RHS) of an expression. If the object is not used at a later stage in the design process (for example, when stitching different parts of the design together), and if the object is not eliminated during synthesis, the object becomes a floating net.

ACTION: Make sure the object is used at a later stage in the design process, or is eliminated during synthesis. If necessary to prevent the object from becoming a floating net, remove the object.
