Quartus

Constant or parameter <text> is used but not defined -- interpreted constant or parameter as quoted string


CAUSE: In a Text Design File (.tdf), you used, but did not define, the specified text as a constant or parameter. Because you did not specify a value for the constant or parameter, the Compiler interpreted the text as a quoted string.
ACTION: If the text is a constant, define it explicitly as a constant prior to using it. If the text is a parameter, its value is a string, and you want to avoid receiving this message in the future, use quotation marks (") around the parameter. If the text is a parameter and its value is not a string, specify a value for the parameter.
NOTE: The Compiler searches for parameter values as described in Parameter Value Search Order.
