Trying to make ALTPLL block working for me.

Two days already not much progress.

I got some observations however:

1. At the end I found out that changes in the MegaWizard for the ALTPLL core doesn't change the behavior at all.

This design is pretty old and originally is done with Quartus II 11.0. Now I am using Quartus II 14.0.

Do you think this may be the problem?

2. In this design two ALTPLL cores are instantiated.

In the Hierarchy view I see those as two separate "magic stick" items but if I double click I get same parameters for both items.

(Adjusting the parameters for the first instance goes to the second automatically )

For the test I have disabled the second ALTPLL instance and i I saw the PLL count in the final compilation report decreasing with one,

so definitely those two instances represents two independent hardware blocks.

Why Megawizard looks at them as a single hardware block?

I am getting very confused
