ID:10581 VHDL Association List error at <location>: formal <name> of mode IN cannot be a Type Conversion or Function Call in named Association List

CAUSE: In an Association List at the specified location in a VHDL Design File (.vhd), you used a Type Conversion or Function Call as a formal. However, the mode of the formal is IN and/or the corresponding actual is the OPEN keyword. To use a Type Conversion or Function Call as a formal, the mode of the formal must be OUT, INOUT, BUFFER, or LINKAGE and the actual cannot be the OPEN keyword.

ACTION: Make sure you use a Type Conversion or Function Call as a formal only when the mode of the formal is OUT, INOUT, BUFFER, or LINKAGE and the corresponding actual is not the OPEN keyword.
