ID:10153 Verilog HDL Function Call or Function Declaration error at <location>: identifier "<name>" is not a function

CAUSE: In a Verilog Design File (.v) at the specified location, either you used a Function Call using a name that is already declared as another nonfunction object, or, in a Function Declaration, you used a name that is already declared in the design as some other type of object.

ACTION: Make sure the Function Call name is spelled correctly, or change the name of the function so that it does not conflict with other identifiers.
