In an Instance Declaration or in-line logic function reference in a Text Design File (.tdf), you instantiated a parameterized megafunction or macrofunction, but you did not specify a value for the specified parameter. The Compiler tried to use an inherited or default value for the parameter, but cannot find one. Therefore, in order to use the parameterized megafunction or macrofunction, you must specify a parameter value.

The Compiler searches for parameter values as described in Parameter Value Search Order. A default value that you specify in a Parameters Statement in a TDF applies only to that TDF; the default value does not apply to the TDF's subdesigns.

Perform one of the following actions:

• Specify a value for the Altera-provided or custom logic function parameter in the logic function's Instance Declaration or in-line logic function reference.

• Specify a default value for the parameter in the Quartus II software.

• Specify a default value for the parameter in the Parameters Statement for the logic function.
