Sharing PLL - using SOPC Builder

Hello folks,

I have instantiated 3 DDR3 Memory controllers into the Nios II CPU and each memory controller uses its own PLL (3 PLL's used). As all the memory controllers operate on the same clock frequency, I want to share the PLL resources.

In the manual from Altera - emi_tut_ddr.pdf, they mention to 'select' the option - use clocks from another controller in the Controller Settings tab of the MegaFunction Wizard ALTMEMPHY for the DDR3 SDRAM. I have selected this option for 2 of my memory controllers.

However, after generating the SOPC, I still end up using 3 PLL's for the 3 memory controllers :confused:. What is it that I am doing wrong? Is there any way to share the PLL resources as I just want to use 1 PLL if possible.

Any help would be great!
