ALT_PLL SIMULATION with Cyclone V, cannot get activity on outputs in Modlesim

Hello, I am using Quartus II version 15 and have started with very simple code that only implements the ALT_PLL function and nothing more. The PLL is very basic, 70MHz in, 3 out... 1 at 70MHz 0degree...

ah_zhi02 has brought up a valid point. As I know, ALTPLL instances are supported in IV series ie Stratix IV and older devices. Starting from V series devices ie Cyclone V, we should use Altera PLL to instantiate the PLL.
