ID:12070 Ignored assignment(s) for "<name>"[<number>][<number>] because "<name>" is not a 2-D bus or array

CAUSE: You made an assignment to the specified 2-D indexed name. However, you did not declare the prefix as a 2-D bus or array in your design. As a result, the Quartus Prime software ignored the assignment.

ACTION: Make the assignment to the full name, or declare the name as a 2-D array in your design.
