Problem during synthesization

As you said I defined such an array type in package whose dimensions were generic integers and used this array type in port decleration. In that case, I got errors again because I was not allowed to use generics, I had to use constants instead. This makes my control on my codes very complicated

I did the previous synthesis in Quartus 8.1 and as I said before it gave me such an error.

I think Quartus 9.1 is able to solve this case.

I didn't get such errors when I synthesized my code with Q9.1

I think Altera solved this "left bound of range must be a constant" issue in Q9.1 even we defined a long std_logic_Vectors with generic intergers.
