Pin for sdram external connection interface in NEEK

Hello, 

 

I'm trying to add an DDR controller to my design in the Cyclone 3 Nios2 Embedded Evaluation Kit. I have checked some examples and all examples export the interfaces "external connection" and "memory" from the controller. In the NEEK documentation I found the PINs to assign to the "memory" interface with the pin planner but I cannot find where I must connect the "external connection". 

 

These are the pins that I don't know where I must to assign them: 

 

external_connection_local_init_done 

external_connection_local_refresh_ack 

external_connection_reset_phy_clk_n
