Modelsim and CycloneV PLL : flat output

Sooooo... I finally managed to make this pll work.

I originally used a first pll to provide its clock input, starting up after a short while. I used its "locked" signal as a reset so that my problematic pll didn't try to sync without input (cf printscreen from the first post). I switched for an independent clock source, starting up without delay, and suddenly it works.

So my conclusion is : never let a pll without input clock, even if it's in reset (at least in modelsim).
