DDR 3 controller clocks usage

Hi 

 

I'm trying to use the DDR 3 controller on the Arria II eval board. 

when I instantiate it in the SOPC builder it creates several clocks. 

 

what clock should I use to drive other parts of the design in order to stay synchronous with the DDR III? 

 

thanks in advance

I assume that you are going to use the avalon-mm interface in the controller to connect with other modules, so in this case you may find the afi_clk or afi_half_clk is useful.
