ID:13708 VHDL error at <location>: can't determine type of object at or near bit string literal "<text>" -- found <number> possible types

CAUSE: In a VHDL Design File (.vhd) at the specified location, you used an object at or near the specified bit string literal. Quartus Prime Integrated Synthesis cannot determine the type of the object because it found the specified number of different possible types for the object, or it found no possible object type. This error may occur because you are using the IEEE Std 1076-1987 version of VHDL in the VHDL Design File.

ACTION: Make sure the design clearly specifies the type of the object. For example, you can explicitly specify a type for an object using a qualified expression, or you can make sure an Architecture Body for an entity uses a declared entity.
