Problem with ALTPLL_RECONFIG in Cyclone III

Device: Cyclone III (EP3C16Q240C8)

I created ALTPLL_RECONFIG with ports to write to the scan chain from external ROM during run time, created ALTPLL with optional inputs for dynamic reconfiguration, generated configuration file (MIF). I done module assembly and begun simulation.

All step's I done like write in ug_altpll_reconfig.pdf ("Implementing Multiple-MIF PLL Reconfiguration Using an External ROM")

After simulation I have this message:

"PLL Reprograming cpmpleted with the following values..."

I take generated MIF file in ALTPLL for my parameters and creat write for rom in wafeform and creat reconfig signal i wafefrom. But after scanchain gone I have no frequencies and lock in low!!!!

On site have no Annex and examples on reconfiguartion Cyclone III in comparison with another devices! :(

Why is not work? :confused:
