ID:10475 VHDL error at <location>: resolution function "<name>" is used but not declared

CAUSE: In Subtype Declaration or Signal Declaration at the specified location in a VHDL Design File (.vhd), you used the specified resolution function. However, you did not declare the resolution function in a Subprogram Declaration. You must declare a resolution function before you can use it.

ACTION: Replace the resolution function with a previously defined resolution function, or define the resolution function in a Subprogram Declaration. However, do not define a resolution function with the name you used in the Subtype Declaration or Signal Declaration if you already used the name for a different construct.
